A process for the production of jet and other heavy fuels, the process including: contacting at least one C3 to C5 isoalkanol with a first catalyst to convert at least a portion of the isoalkanol to isoalkene, isoalkene dimers, and water; contacting at least a portion of the isoalkene dimers with a second catalyst to convert at least a portion of the isoalkene dimers to isoalkene trimers; hydrotreating the isoalkene trimers to form isoalkanes useful as a jet fuel, kerosene, or other heavy fuels.

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.
