Systems and methods are provided for conversion of methanol to gasoline in an integrated system that can also upgrade light paraffins generated by the methanol conversion process to aromatics. In some aspects, the integrated configuration can include integration of the stage for upgrading of light paraffins to aromatics into the product separation sequence for processing of the methanol conversion effluent. In other aspects, the integrated configuration can further include sharing a common catalyst between the methanol conversion stage and the stage for upgrading light paraffins to aromatics.

Systems and methods are provided for conversion of oxygenate-containing feeds to a hydrocarbon effluent that includes a naphtha boiling range portion with an increased research octane number and/or increased octane rating. The conditions for converting the oxygenate-containing feed can correspond to conversion conditions for fluidized bed operation and/or moving bed operation, with a low acidity catalyst that also includes phosphorus to improve the hydrogen transfer rate relative to the expected hydrogen transfer rate for a low acidity catalyst. In addition to providing a naphtha fraction with an improved research octane number and/or octane rating, the amount of durene in the naphtha fraction can be reduced or minimized.

A method for thermal processing and catalytic cracking of a biomass to effect distillate oil recovery can include, particle size reduction. slurrying the biomass with a carrier fluid to create a reaction mixture, slurrying a catalyst with a carrier fluid to create a catalyst slurry, heating the reaction mixture and/or the catalyst slurry, and depolymerizing the reaction mixture with the catalyst. The reaction mixture can undergo distillation and fractionation to produce distillate fractions that include naphtha, kerosene, and diesel. In some embodiments, thermal processing and catalytic cracking includes vaporization of the biomass followed by distillation and fractionation. In some embodiments, a resulting distillate can be used as a carrier fluid. In some embodiments, the method can include desulfurization, dehydration, and/or decontamination.
