Either your grow an oilseed, extract the oil and make biodiesel from the oil. Or you do some form of pyrolysis, to get liquid fuel. Or you do pyrolysis to make syngas and you make diesel similarly to how the Germans did in WWII. All the techniques and machinery are pretty easy to find on the web depending on which you want to do. On a small scale, the oil and use and alcohol with a catalyst to make biodiesel is likely the easiest. The Dakota Gasification plant cost 4.5 billion dollars when it was constructed back in Jimmy Carter's time. It uses coal to make either natural gas or syngas which is used to make anhydrous ammonia. A plant to use ag products would be similar. Marv
