Why is an acid esterification or pre-treatment step required for processing a tallow feedstock into biodiesel and not required when processing a soybean feedstock?

Because tallow contains more complex sugars that require an additional step before they can be further processed. :)

What is the plural of feedstock?
The plural of feedstock is feedstocks. As in "the feedstocks are there".
What materials is plastic made from?
petrochemicals, from crude oil feedstock
Does bio diesel smell?
Yes! it does! Even with the engine warmed the smell is still very noticeable. It is related to the feedstock used, if oil-based feedstock is used then it will smell like "french fries". If the feedstock is animal-based fat then it will smell like "pork" or "beef". At least on my 1.9 TDi with catalytic converter.
Biodiesel: Quite Possibly the World’s Best Fuel?
As automakers embrace hybrid or electric technology and futurists dream of a hydrogen highway, another alternative fuel source quietly powers thousands of cars and trucks throughout the world. Biodiesel, which is a diesel fuel made of natural sources, offers significant environmental benefits as well as being able to be produced without the use of imported petroleum. Biodiesel is made by mixing some sort of oil from biological sources with an alcohol to form a fuel made of long-chain alykl esters. The first diesel engine, designed by Rudolph Diesel in 1893, actually ran on peanut oil based biodiesel. In fact, biodiesel was used as a fuel in a number of countries from the 1920’s through World War II. Biodiesel can be made of just about any oil product. Although the preferred refinery feedstock is vegetable oil with rapeseed and soybean being the most popular, it can also be made from waste vegetable oil from fryers, animal fats, algae, or even coffee grounds. In fact, the waste fat from one Tyson chicken producing plant can generate enough biodiesel to run 8000 cars going 15,000 miles per year at 40 miles per gallon, which is the EPA highway rating for a Volkswagen Jetta TDI. Using waste products as a feedstock for biodiesel refineries has three unique benefits--it reduces the amount of these products being dumped in landfills, it allows for recycling of the products which is always positive, and it eliminates the shifting of resources from food to fuel production which has marked the ethanol industry. Not only is biodiesel efficient to produce, but it is also a uniquely efficient version of a uniquely efficient fuel. Diesel engines tend to have 20-40% better performance than gasoline coupled with over 10% reductions in greenhouse gasses. Biodiesel-powered engines have an over 50% reduction in greenhouse gasses over regular diesel engines. In addition, biodiesel is naturally sulfur free, making it a cleaner fuel than diesel. It is higher in cetane, which is the “active ingredient” in petrodiesel, and it also has lubricating properties that can extend the life of the engine using it. In fact, it is frequently blended with modern ULSD (ultra-low sulfur diesel) as an enhancement.
What limits the amount of synthetic ethanol produced?
the amount of feedstock avalialble
What is a cellulosic feedstock?
"Cellulosic" means that the material contains cellulose. Cellulose is found in wood, paper, grass and other plant matter. If it is used as a starting point for producing something, such as ethanol, that would make it a feedstock.
Are there any sodium chloride products?
Sodium chloride is an important feedstock for the chemical industry.
Why are hydrocarbons important to humans?
Hydrocarbons are used as fuels, solvents feedstock in organic chemistry.
Why is methane an important gas?
Methane is a very common fuel and feedstock for chemical industry.
Pros and cons of using biodiesel?
Biodiesel has been controversial. I've include 4 links that explain the issues with biodiesel and biofuels in general. First, the pros 1. It works. A mix of diesel and biodiesel may be necessary on some cars. It can be used in buses and trains. Use of biodiesel has been increasing. 2. We have a limited supply of fossil fuels. The ability to "grow our energy" extends the lifetime of our natural resources. 3. Biodiesel burns cleaner than regular diesel, based on particulates from tail-pipe emissions (see wikipedia link on environmental problems). 4. We must import oil, and this creates a dependence on other countries. It would be devastating to our economy if any country cut us off from this supply. So, biodiesel adds to our energy security. 5. Adding to the supply of fuels should help moderate prices of these fuels by making them less scarce commodities. 6. Biodiesel is good for farmers around the world. It is an additional crop they can grow. Now, the cons, 1. Converting crops into biofuels will mean that less of there will be less available produce to feed people. This drives up the price of food. One crop in particular is soybeans, which is used as animal feedstock. So as soybeans become more valuable to make fuels, meat prices will increase. 2. Biodiesel (or more generally biofuels) means that there will be extensive deforestation in tropical areas such as the Amazon rainforest to grow sugar cane and soybeans for biofuels. This will have a large impact on environment and CO2 emissions. CO2 pollution is linked to global warming. Thus some environmentalists are calling biodiesel a worse alternative than natural diesel. 3. The increase in palm oil farms in Asia has lead to use of pesticides and contamination of drinking water supplies. (see wikipedia link) 4. Biodiesel is not a cleaner fuel to burn. It produces 10% more nitrogen oxide tail pipe emissions than diesel. (see Wikipedia link on environmental issues). 5. Promoters of biofuels have created a false impression of an easy solution to energy needs. Due to all the problems they cause, these fuels can not satisfy our needs. I suggest that you read through the links provided. Perhaps there are more pros and cons. Certainly, the question of whether biodiesel burns cleaner is a difficult one. Good luck! :) Biodiesel is less pollutive. It is safer to handle :( It is more expensive at the moment Not approved by all auto dealers
What is cyanide used for in industry?
Applications of cyanides:- gold extraction- feedstock for chemical industry- poison
What treatment does synthetic ethanol feedstock needs?
