Hi Doug,
The biodiesel plant is a project to convert used veggie oil and newly pressed canola oils in to biodiesel.
I realize the Changfa's can run on waste veggie oil, but my studies show that waste oils contain many things which engines don't like. For example, fatty acids and glycerines which coke up the valves and rings.
I think the Lister(oids) can handle used oils much better.
In any case, I want ASTM certified Biodiesel. I am building a used oil processing system which removes moisture, particles, and acids from the oil prior to processing. This stage utilizes a centrifuge spinning at 6000 rpm. The the oil then goes through a 4 stage process of chemical cracking, polishing, filtration, and final filtering before use.
I have designed and built the pre-processor and I am now building the Reactor for the chemical cracking process.
The process removes glycerines and impurities, and the chemical process adds carbon molecules creating a diesel fuel.
