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 olefins 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.

Abstract: Disclosed is a process for converting C2-5 alkanes to higher-value C5-24+ hydrocarbon fuels and fuel blendstocks including reacting the C2-5 alkanes in a thermal olefination reactor operating at a temperature, pressure and space velocity to convent the alkanes to olefins and in the absence of both a dehydrogenation catalyst and steam. At least a portion of the product olefin stream is oligomerized using a zeolite catalyst to crack, oligomerize and cyclize the product olefins to form the fuel products, which are then recovered. The process is useful in removing sulfur and nitrogen-based compounds in a single step process, while reducing total costs of processing and eliminating the need for additives used in the field.
