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.

Dual stage light alkane conversion to fuels

A catalyst comprising NiO, a metal mixture comprising at least one of MoOor WO, a mixture comprising at least one of SiOand AlO, and PO. In this embodiment the metal sites on the catalyst are sulfided and the catalyst is capable of removing tar from a synthesis gas while performing methanation and water gas shift reactions at a temperature range from 300&#xb0; C. to 600&#xb0; C.

Low temperature sulfur tolerant tar removal with concomitant synthesis gas conditioning

A catalyst comprising of NiO; AlO; and ZnO. The catalyst is capable of greater than 5% sulfur removal from a synthesis gas at a temperature range from 300&#xb0; C. to 600&#xb0; C.

Low temperature sulfur tolerant tar and sulfur removal with concomitant synthesis gas conditioning

Biomass derived gas oil is blended with petroleum derived gas oil and upgrading into more salable and more valuable products by co-processing the blended material in a gas oil hydrocracking system comprising two reactors where the blended material is first hydrotreated and then hydrocracked.

Upgrading sugar-alcohol derived gas oil in a gas oil hydrocracker

A catalyst comprising NiO, a metal mixture comprising at least one of MoO3 or WO3, a mixture comprising at least one of SiOand AlO, and PO. In this embodiment the metal sites on the catalyst are sulfided and the catalyst is capable of removing tar from a synthesis gas while performing methanation and water gas shift reactions at a temperature range from 300&#xb0; C. to 600&#xb0; C.

Oxygenate feedstocks derived from biomass are converted to a variety of fuels including gas, jet, and diesel fuel range hydrocarbons. General methods are provided including hydrolysis, dehydration, hydrogenation, condensation, oligomerization, and/or a polishing hydrotreating.
