Abstract: Disclosed herein are processes for the production of hydrocarbon fuel products from C2-5 alkanes. Methane is converted to ethylene in a methane thermal olefination reactor operating at a temperature of at least 900° C. and a pressure of at least 150 psig, and without a dehydrogenation catalyst or steam. C2-5 alkanes are converted to olefins in a C2-5 thermal olefination reactor operating at a temperature, pressure and space velocity to convert at least 80% of the alkanes to C2-5 olefins. The ethylene and C2-5 olefins are passed through an oligomerization reactor containing a zeolite catalyst and operating at a temperature, pressure and space velocity to crack, oligomerize and cyclize the olefins. In one aspect, methane in the effluent of the oligomerization reactor is recycled through the C2-5 thermal olefination reactor. Methods for the thermal olefination of methane are also disclosed.

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.

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.
