1. An integrated process to make high value linear alcohols, branched alcohols and linear olefins from synthesis gas wherein:
a) separating a Fischer-Tropsch synthesis product into HFTL and LFTL fractions;
b) contacting the LFTL fraction with a dehydration catalyst to produce a dehydrated LFTL fraction comprising olefins and paraffins;
c) separating the dehydrated LFTL fraction into at least C5–C9 and C10–C13 olefin/paraffin fractions; and
d) contacting the C5–C9 and C10–C13 olefin/paraffin fractions with synthesis gas to form C5–C9 and C10–C13 aldehyde/paraffin fractions.
