Abstract: Catalyst systems are provided, along with corresponding methods, for single stage conversion of synthesis gas to fuel boiling range products with increased selectivity for either naphtha production (C5-C9) or distillate production (C10-C20). The increased selectivity for naphtha production or distillate production is provided in conjunction with a reduced selectivity for higher boiling range components (C21+).

Abstract: Systems and methods are provided for integrated conversion of biomass to ultimately form naphtha and/or diesel boiling range products. The integrated conversion can include an initial conversion of biomass to alcohols, such as by fermentation, followed by conversion of alcohols to olefins and then olefins to naphtha, jet, and diesel boiling range compounds, with high selectivity for formation of diesel boiling range compounds. The integrated conversion process can be facilitated by using a common catalyst for both the conversion of alcohols to olefins and the conversion of olefins to naphtha and/or diesel boiling range compounds. For example, ZSM-48 (an MRE zeotype framework structure catalyst) can be used as the catalyst for both conversion of alcohols to olefins and for oligomerization of olefins with increased selectivity for formation of diesel boiling range products.

Abstract: Processes for the catalytic conversion of alcohols and/or ethers to olefins over zeolite catalysts are described. Self-bound ZSM-5 and metal containing variants, such as Zn ZSM-5, produce high yields of olefins, particularly C3+ olefins, between 250 and 450° C.
