Abstract: A process for converting C2-5 alkanes to higher value C5-24 hydrocarbon fuels and blendstocks. The C2-5 alkanes are converted to olefins by thermal olefination, without the use of a dehydrogenation catalyst and without the use of steam. The product olefins are fed to an oligomerization reactor containing a zeolite catalyst to crack, oligomerize and cyclize the olens to the fuel products which are then recovered. Optionally, hydrogen and methane are removed from the product olefin stream prior to oligomerization. Further optionally, C2-5 alkanes are removed from the product olefin stream prior to oligomerization.
