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.

Methods for making higher-octane fuel components from a feed stream of C8+ paraffins, including catalytically cracking the C8+ paraffins using a Zeolite catalyst to produce a reaction product of mid-chain paraffins and olefins and short-chain paraffins and olefins. The reaction product comprises liquid phase paraffins having an increased Octane Value over the feed stream paraffins. The reaction product further comprises a gas phase of short-chain paraffins which are separated from the liquid phase. In embodiments, the short chain olefins are hydrogenated to form mid-chain paraffins and a gas phase containing short-chain paraffins.

The present disclosure provides for a separations system for separating ethylene, 2-methylbutane and at least one unsubstituted (C6-C12) hydrocarbon in a multi-component condensate mixture. The separations system includes a feed conduit in fluid communication with a source of the multi-component condensate mixture, a stripper column in fluid communication with the feed conduit, where the stripper column separates the multi-component condensate mixture into a heavies component mixture with at least one unsubstituted (C6-C12) hydrocarbon, and a top mixture having a medium component (s) that include at least the 2-methylbutane and a light component (s) that include at least the ethylene. The separations system further includes a flash drum that separates the top mixture into the medium component (s) and the light component (s). The separations system does not include a distillation column disposed between the source of the multi-component condensate mixture and the flash drum.

A method of making fuel including adding alcohol to a reactor with a zinc dihalide salt and heating the reactor to reflux, thereby forming a mixture. Water is removed from the mixture using azeotropic distillation. The mixture is distilled, thereby forming oligo(alkenes).sub.n and residual alcohol. The oligo(alkenes).sub.n are distilled using fractionation, thereby forming a first, a second, a third fraction, and removing the residual alcohol. The first fraction includes oligo(alkenes).sub.n with n ranging from 2 to 4, the second fraction includes oligo(alkenes).sub.n with n ranging from 4 to 8, and the third fraction includes oligo(alkenes).sub.n with n ranging from 8 to 12. The first, second, and third fractions are hydrogenated, thereby forming oligo(alkanes).sub.n. The first fraction includes oligo(alkanes).sub.n with n ranging from 2 to 4, the second fraction includes oligo(alkanes).sub.n with n ranging from 4 to 8, and the third fraction includes oligo(alkanes).sub.n with n ranging from 8 to 12.
