Abstract: A process and system for the conversion of a feedstock comprising C3-C5 light alkanes to a C5+ hydrocarbon product, for example, a BTX-rich hydrocarbon product, by performing the alkane activation (first-stage) and the oligomerization/aromatization (second-stage) in separate stages, which allows each conversion process to occur at optimal reaction conditions thus increasing the overall hydrocarbon product yield. The alkane activation or first-stage is operated at a higher temperature than the second-stage since light alkanes are much less reactive than light olefins. Since aromatization of olefins is more efficient at higher pressure, the second-stage is maintained at a higher pressure than the first-stage. Further, fixed-bed catalysts are used in each of the first-stage and the second-stage.

Abstract: The present disclosure relates generally processes and systems for converting a mixture of light hydrocarbons to liquid transportation fuels by first cracking the light hydrocarbons to an intermediate comprising olefins, which is converted by contacting with a catalyst comprising at least one zeolite in two separate conversion stages with an intervening recovery of liquid product. The first stage conversion favors oligomerization of larger olefins to form diesel range products that are collected prior to directing unconverted smaller olefins to be oligomerized in a second stage conversion conducted at a higher temperature and lower pressure.

Abstract: The present disclosure relates generally processes and systems for converting a C2-C7 light alkanes feed to liquid transportation fuels or value-added chemicals. The feed is contacted with an aromatization catalyst at a temperature and pressure that selectively converts C4 and larger alkanes to an intermediate product comprising monocyclic aromatics and olefins. Following separation of the aromatics and C5+ hydrocarbons from the intermediate product, unconverted C2-C3 alkanes are thermally-cracked to produce olefins that are subsequently oligomerized to produce a liquid transportation fuel blend stock or value-added chemicals.
