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.
Claims18
A composition comprising paraffins falling in the C12-C24 range, wherein:
- at least 75 wt % of the composition comprises even carbon number paraffins;
- the paraffins and the even carbon number paraffins are produced from a renewable biological feedstock by a process comprising hydrogenation and hydrogenolysis in a slurry bubble column reactor followed by in a fixed-bed reactor;
- the even carbon number paraffins comprise n-dodecane and n-tetradecane;
- and the composition is undistilled.
A composition comprising paraffins falling in the C12-C24 range, wherein:
- at least 80 wt % of the composition comprises even carbon number paraffins;
- the paraffins and the even carbon number paraffins are produced from a renewable biological feedstock by a process comprising hydrogenation and hydrogenolysis over a bimetallic catalyst in a slurry bubble column reactor followed by in a fixed-bed reactor;
- the even carbon number paraffins comprise n-hexadecane and n-octadecane;
- and the composition is undistilled.
