Abstract
Paraffin compositions including mainly even carbon number paraffins, and a method for manufacturing the same, is disclosed herein. In one embodiment, the method involves contacting naturally occurring fatty acid/glycerides with hydrogen in a slurry bubble column reactor containing bimetallic catalysts with equivalent particle diameters from about 10 to about 400 micron. The even carbon number compositions are particularly useful as phase change material.
Claims21
A process for producing hydrocarbons from biomass, comprising the steps of:
- (a) providing a biological feedstock containing free fatty acids, fatty acid esters, or combinations thereof;
- and
- (b) subjecting the biological feedstock to heat in the presence of hydrogen with a catalyst slurry having an equivalent particle diameter of about 10 microns to about 400 microns to produce hydrocarbons which are predominantly even carbon number paraffins.
