shrimp shell catalyst

[Raven]

here's a news tidbit for making quick diesel fuel

all biofuel uses a catayst to get the oil mix to turn to biofuel
-------------------------------------------------------------------------------
The researchers at Hua Zhong Agriculture University in Wuhan, China, and their colleagues first heated shrimp shells for hours, transforming it into a highly porous framework material. They next loaded its extensive surface area with potassium fluoride, making it catalytic. In lab tests, the cheap, biodegradable shrimp shell catalyst converted canola oil to biodiesel faster and more efficiently than some conventional catalysts, demonstrating 89 percent conversion in three hours.
The new catalyst also can be reused and the manufacturing process led to less pollution and waste, the scientists note.

pretty cool considering shrimp shells were just a waste product
