Abstract:
Vegetable oils have been investigated as a way to provide a renewable source for diesel fuel. A successful approach to using

vegetable oils in diesel engines has been transesterification of the oils with simple alcohols to produce mono-alkyl esters, or

biodiesel. A recent development in the area of alternative diesel fuels is a fuel produced from vegetable oils and animal fats using

specially modified hydrogenation processes in a conventional petroleum processing facility. This fuel is usually called renewable

diesel. This project has focused on developing an understanding of the processes involved with renewable diesel production from

a variety of bio-based feedstocks. The project has determined that Raney nickel is an effective catalyst for hydrogenation and

deoxygenation of fatty acids, which is a key step in the production of renewable diesel. We have also determined that

deoxygenation can take place in a hydrogen-lean environment so that fatty acids can be deoxygenated without having to be

completely hydrogenated. This is an important observation because hydrogenation affects the fuel’s cold flow properties by

increasing its melting point. We are continuing to explore decarboxylation without full hydrogenation as a way to provide

renewable diesel with superior low temperature properties.
