Abstract
A process () to produce olefinic products suitable for use as or conversion to oilfield hydrocarbons includes separating () an olefins-containing Fischer-Tropsch condensate () into a light fraction (), an intermediate fraction () and a heavy fraction (), oligomerizing () at least a portion of the light fraction () to produce a first olefinic product () which includes branched internal olefins, and carrying out either one or both of the steps of (i) dehydrogenating () at least a portion of the intermediate fraction () to produce an intermediate product () which includes internal olefins and alpha-olefins, and synthesizing () higher olefins from the intermediate product which includes internal olefins and alpha-olefins to produce a second olefinic product (), and (ii) dimerizing () at least a portion of the intermediate fraction to produce a second olefinic product (). At least a portion of the heavy fraction () is dehydrogenated () to produce a third olefinic product () which includes internal olefins. Also provided is a process () to produce paraffinic products suitable for use as or conversion to oilfield hydrocarbons which includes separating () a Fischer-Tropsch wax () into at least a lighter fraction () and a heavier fraction (), hydrocracking () the heavier fraction () to provide a cracked intermediate (), and separating () the cracked intermediate () into at least a naphtha fraction (), a heavier than naphtha paraffinic distillate fraction () suitable for use as or conversion to oilfield hydrocarbons, and a bottoms fraction () which is heavier than the paraffinic distillate fraction ().
