An Introduction to Bioenergy & Biofuels
United States
Registrace 7. 07. 2015
Biomass is all around us and understanding where it fits in our energy and chemicals paradigm is an important part of using it effectively and sustainable.
This channel will host a series of videos that serve as an introduction to bioenergy core concepts and technologies, technical background, and the economic, environmental and socio-cultural sustainability of bioenergy. These short videos have been designed to communicate the bioenergy basics needed for people from diverse backgrounds to understand what bioenergy is and where it fits in their region. The objective is to enable dialogue and learning so that bioenergy discussions become more commonplace.
Written slide notes and support materials for each lecture can be found at the Bioenergy Education Initiative site (agsci.oregonstate.edu/bioenergy-education) at Oregon State University. An associated online E-campus course, BRR 350 Introduction to Regional Bioenergy is also available. This was made possible by USDA AFRI

Lecture 13 Pyrolysis & Liquefaction
Thermal conversion does not make things, it really just breaks them down. This means if you want to make large sized chemicals or chemicals that don’t look like small pieces of lignin and cellulose, thermal conversion cannot be the only conversion utilized or shouldn’t be the conversion of choice. This is especially relevant with pyrolysis as the products look very much like small pieces of cellulose and lignin.
Pyrolysis Oil is often called bio-oil. This is a silly naming convention because pyrolysis oils look nothing like oils. They have an entirely different set of organic chemistries almost entirely the opposite of what oils like petroleum and vegetable oil have. The name bio-oil was coined because it was a thick, dark product that looked like oil, not because it actually was oil. Based on that kind of logic molasses and liquid chocolate should also be call oils. At this point we are stuck with the misleading name bio-oil, but it is important to remember it is only called oil because of how it looks sometimes, not because it has anything in common with real oils.

Lecture 18 Photosynthetic Organisms and Animals
zhlédnutí 2,4KPřed 8 lety
Photosynthetic organisms like algae and plants do not need to be fed sugar or kept in a low O2 environment like fermentation microbes. They produce their own sugars using photosynthesis and they do not really need O2 as much as they need CO2. Photosynthetic organisms can be high tech like algae used for fuels/oil or low tech like canola and peanut plants that are used to produce vegetable oils....
Lecture 17 Fermentations
zhlédnutí 3,9KPřed 8 lety
Biomass biological conversions are like having an aquarium. It is technically an ecosystem, so you have to consider all the angles and how things will get along. You have to keep everything alive by feeding it and making sure the conditions are correct, and most importantly you have to keep it wet. Living things don’t do dry well, so biological conversions range from wet to completely submerged...
Lecture 14 Biomass to Parts
zhlédnutí 2,2KPřed 8 lety
There are a lot of biomass chemical conversion products. They range from cell wall polymers like cellulose and lignin to much smaller things like sugars and chemicals like furfural. It is important to appreciate the wide range of commodity, specialty, and fine chemicals that can be produced from biomass using chemical conversion processes. From a conversion perspective, chemical conversions are...
Lecture 15 Biomass Parts to Products
zhlédnutí 10KPřed 8 lety
We are all using biomass chemical conversions right now and we have recently done a biomass mechanical conversion. Every time you cut your food to eat it and every time you chew it before swallowing you are doing a mechanical conversion. You reduced to size to get it into the reactor (your mouth). Then you chewed it so that it could be broken down easier in your stomach, so technically you had ...
Lecture 21 USA Fuel Paradigm
zhlédnutí 562Před 8 lety
Most of us already know the US pretty much stands alone in terms of how cheap our gasoline is and how much we use. This is an unusual relationship because usually when demand is high, price gets higher and we definitely have the demand, but not the price to match. It doesn’t completely abide by the normal fuel supply and demand economics of the rest of the world because the US has done some uni...
Lecture 19 Integrated Biorefineries
zhlédnutí 7KPřed 8 lety
Most bioenergy ideas and businesses use combinations of different conversion processes and then come up with a cool name for it that get attention (marketable). When someone tells you about a bioenergy conversion process you need to be able to identify the basic parts. There are generally only 4 basic possibilities; Thermal Conversions, Chemical Conversions, Biological Conversions, and Mechanic...
Lecture 20 Biorefining in North America
zhlédnutí 984Před 8 lety
Fossil fuels as a carbon source are consolidated compared to biomass which is distributed. This needs to be considered in more detail because it directly relates to petroleum refining. Oil is concentrated in select places in huge underground reservoirs and its pump-able. As a result, the United States and North America are covered in biomass, not oil. The vast majority of the oil is only found ...
Lecture 16 Oil Conversions & Syngas Conversions
zhlédnutí 1,6KPřed 8 lety
Breaking biomass into its parts and breaking those parts into chemicals and fuels is very focused on the biomass cell wall. However, biomass isn’t all cell wall and it can be squeezed to produce oils in some cases. These oils get turned into fuels using their own class of chemical conversions. Biodiesel is produced by chemical reaction called trans-esterification that actually adds more oxygen ...
Lecture 12 Combustion & Gasification
zhlédnutí 15KPřed 8 lety
There are many different type of thermal conversion products. Thermal conversions can be used to produce solid, liquid, and gaseous products and a wide variety of each type depending on reaction conditions. Unfortunately it can also be a very confusing field because a lot of the same products have different names that would lead you to believe they are not even related. As you learn more about ...
Lecture 11 Mechanical Conversions Drying & Densification
zhlédnutí 2,1KPřed 8 lety
Biomass is almost always wet and often at least some of this water has to be removed before it can be used/processed. Drying is a very expensive and often overlooked step in using biomass. Biomass drying requires a considerable source of energy because removing water from biomass is harder than getting it to boil out of a pot and wood dryers are not all that efficient because it’s hard to heat ...
Lecture 23 Basic Energy Economics
zhlédnutí 3,9KPřed 8 lety
Futures trading is very common. The speculative commodities trading community flocked to the energy market after 2000. Crude oil futures and gasoline futures are traded at New York Mercantile Exchange (NYMEX) and Tokyo Commodity Exchange (TOCOM). Ethanol futures are traded at Chicago Board of Trade (CBOT). Speculation did some interesting things to the price of oil around the time of the recess...
Lecture 25 Emissions and Sustainability Considerations
zhlédnutí 826Před 8 lety
The word sustainability is derived from the word Sustain which can mean to “maintain", "support", or "endure”. For quite some time now sustainability has been used more in the sense of human sustainability on planet Earth with a very commonly quoted definition being “sustainable development is development that meets the needs of the present without compromising the ability of future generations...
Lecture 24 Process Analysis with LCA and TEA
zhlédnutí 879Před 8 lety
The Triple bottom line incorporates the notion of sustainability into business decisions. It is an accounting framework with three dimensions: social, environmental and financial. The dimensions are also commonly called the three Ps: people, planet and profit and are referred to as the "three pillars of sustainability". Interest in triple bottom line accounting has been growing in both for-prof...
Lecture 22 Renewable Energy and Fuel Policy
zhlédnutí 536Před 8 lety
Despite the challenges, blending of ethanol in gasoline continues to be practiced in the U.S. and will likely continue to become a larger part of our fuels infrastructure. There is a lot of rationale behind this approach, which is why it is a part of our biofuel policy and our strategic development in the domestic energy industry. The government has mandates on bioenergy production and use, tax...

It was absolutely a strong primer, those 25 micro-lectures. I have 10 ECTS points on biofuel next semester, and it was just insightful and useful lectures. Thank you❤
Why emission are less after pelletizatio of same saw dust with only mechanical conversion by pressure and shape
Excellent
why no updates？
Amazing work!
Ver interedting. Following. Done pyrolysis used in 1984
Thus formed flame is golden
Forced air into combustion zone by steam jet produces more hydrogen
Thanks very good
With liquefaction what by products can be created from the biocrude
Very clear explanation 😃
thanks for the video! It is very informative and covers many things I can't find on youtube!
Thank You Very Much. All the liquids produced by pyrolysis are called Bio Oils.... Which is completely wrong and i fully agree with this. It is time to name them as Water Soluble and Non Water Soluble Liquids ( At ATM ) - just for simple understanding. The water Solubles are Known As Wood Vinegar which has far more use and the value of Wood Vinegar Justifies The Real Value of the Biomass Pyrolysis...
Sir what is the difference between torrefaction and combustion
great
thank you!
amazing best luck ,, thanks a lot www.fb.com/biodieseljordan
still around?
still around?
WOW
Please any help, I fabricated a downdraft gasifier but as flame it, it doesn't support glowing
I got confused around min. 6:45 with the comparison of fast and slow pyrolysis, you say Fast pyrolysis yields the most bio-oil but with lower quality, slow pyrolysis produces better product but poor yields per pound of biomass, however in the graphic of 3:46 and in 5:16 you explain the arrows of the yields and qualities of bio-oil, so which one is which one???
Great work
very informative. Thank you for the video
It looks like Methanol is the winner here. I'm gonna have to procure some catalyst materials, burn some feedstocks to see which ones have the least contaminants, and go from there.
perfect
thx alot
Thanks!
This is an amazing work. Am presently working on a similar work and will be happy to apply this knowledge on getting there. Thanks for uploading.
Greetings from Mexico! i'm actually researching and reading biorefineries topics because i want to make a master in that area, :D in fact, i made a bioprocess for chitin extraction via bacterial degradation in my last semester of college, that went fantastic! Congratulation for your videos! hoping you may upload more of them in the future :)
good
good
Wow...great lecture!!
good lecture
Are these subsidies/tax breaks cumulative or periodical? Are the numbers representative of the total amount of subsidies within say, the last 100 years?
Hey, in all the videos so far where you ask us to visit "the attached link"; there have not been any attached links.
Thank you for the comment. The channel is a little rough around the edges because the lectures were designed for a class, not CZcams. However, each CZcams video will eventually be linked to the education resources available at hardwoodbiofuels.org/ and agsci.oregonstate.edu/bioenergy-education. Here you will be able to find the links and associated support material for each lecture

Nice!
Thank you for this information and veru usefull to me.
I'm wondering who is managing this channel. Would you be able to send me a note so that we can connect? nora.haider@wsu.edu Thanks! Nora
