A catalyst for converting dimethyl ether into light olefins, including ethylene and propylene. The catalyst comprises a mixture of two zeolites, ZSM-5 and ZSM-35, intimately mixed and kept in close proximity in a porous extruded binder system. The resulting combination of zeolites demonstrates a synergistic effect with respect to the conversion of the dimethyl ether and has improved resistance to deactivation due to carbon and coke formation than the individual zeolites alone when operating in this reaction. The catalyst is used to produce ethylene and propylene from a feed mixture containing methanol, dimethyl ether and water.

Hybrid extruded mixed zeolite catalysts for synthesis of light olefins

A process for producing acrylic acid from carbonaceous materials such as biomass. The carbonaceous material, such as biomass, is gasified to produce synthesis gas. The synthesis gas then is subjected to a plurality of reactions to produce acrylic acid.

Production of acrylic acid and ethanol from carbonaceous materials

A process for producing ethanol from synthesis gas by reacting the hydrogen and carbon monoxide of the synthesis gas to provide methanol, which then is subjected to dehydration to produce at least one ether, such as dimethyl ether. The ether, such as dimethyl ether, then is subjected to carbonylation with unreacted carbon monoxide from the synthesis gas to provide at least one acetate, such as methyl acetate. The acetate then is subjected to hydrogenolysis to produce ethanol.

Production of ethanol from synthesis gas

A process for producing alcohols from carbonaceous materials such as biomass. The carbonaceous material, such as biomass, is gasified to produce synthesis gas. The synthesis gas then is subjected to a plurality of reactions to produce alcohols having at least four carbon atoms such as butanol and isobutanol.

Production of alcohols having at least four carbon atoms from carbonaceous materials

A process for producing alcohols having three carbon atoms from carbonaceous materials such as biomass. The carbonaceous material, such as biomass, is gasified to produce synthesis gas. The synthesis gas then is subjected to a plurality of reactions to produce alcohols such as n-propanol and isopropanol.

Production of alcohols having three carbon atoms from carbonaceous materials

A method of producing at least one oxygenated compound, such as methyl acetate, dimethyl ether, and formaldehyde, by reacting dimethyl carbonate and carbon monoxide in the presence of a faujasite zeolite, zeolite Beta, Linde Type L (LTL) zeolite, or MCM-41 zeolite.
