Vegatable oil into gasoline?

Post by ChuckBaker » Fri May 02, 2008 5:37 pm

If we can take regular petroleum oil and turn it into diesel fuel and gasoline.

And vegetable oil in to bio diesel why can't we take vegetable oil and turn it into bio gasoline?

Is there any one working on this?

During the refining process, heavy crude is distilled into lighter fractions, including lube oil, diesel, kerosene, and many other lighter hydrocarbons. Gasoline is a mixture of these light hydrocarbons. Vegetable oil is already a refined light oil. It does not contain the other compounds. Vegtable oil can be used as a fuel without any further processing. The only drawback to straight veggy oil is it has to be heated to flow at the same viscosity as diesel. Converting it to biodiesel does away with the need to preheat. Biodiesel is only a good alternative IF made from waste oil or waste products contaning oil. If you have to grow new source oil, it takes more energy to produce than you get back, just like the other bad alternative, ethanol.

Do you have info to back this?
There are two tractor producers that make bi fuel tractors ie diesel or crude veggy oil. The process to make veggy oil is simple, no chemicals and the byproduct is a high value livestock feed.

But you still have to plant, grow, harvest and then process, all steps using energy of some kind. If you pick a crop that is easier and simpler to grow and harvest then there may be some gain. Something like industrial hemp might prove out to be OK. And, as we are learning now from the U.S. model for ethanol, food prices go up. Corn prices are climbing due to there use in US ethanol production. I'm no expert but some research into does show this to be true.

When it comes to crude veggy oil it is easily energy ahead. The byproduct from pressing the seed is worth more then the seed itself. The oil is a bonus. To others the meal is the bonus.
Soybean only has 12-18% but quit a few grow is because theres more meal per ton of seed processed and has about a 43% proteen content and is worth well over 100$ a US ton.
A side note, not all oil seed make the grade for human consumption.
Here's a list of % of oil in the seed.

Cotton 30-35%
Soybean 12-18% 335
Linseed (Flax) 35-40%
Mustard Seed 35-40%
Sesame 35-40%
Safflower 38-45%
Sunflowers 40-45%
Camelina Sativa 40-45%
Peanuts 40-45%
Rapeseed 38-45%
Canola 40-45%

There's alot of misinformation. The corn used for ethanol is field corn not corn for humans. If the process is done rite the byproduct from making ethanol can be used for livestock feed as well whats done in Brazil.
As for the cost of corn and other foods going up just at the cost of oil. According to the USDA there hasn't been any cutbacks in con for human consumption.

Canada dropped the ball when it comes to hemp for fiber. As for oil i need to see research to it's viability.
