Metal-Loaded Zeolite Catalysts for the Halogen-Free Conversion of Dimethyl Ether to Methyl Acetate

A catalyst for the carbonylation of dimethyl ether to methyl acetate. The catalyst comprises a zeolite, such as a mordenite zeolite, at least one Group IB metal, such as copper, and/or at least one Group VIII metal, such as iron, and at least one Group IIB metal, such as zinc. Such a catalyst with combined metals provides enhanced catalytic activity, improved stability, and improved selectivity to methyl acetate, and does not require a halogen promoter, as compared to a metal-free or copper only zeolite.

Ethanol Production via Dimethylether Recycle

This invention relates to a process for producing ethanol comprises supplying a feed comprising carbon monoxide, hydrogen and dimethyl ether to a reaction zone operated under conditions such that (i) part of the carbon monoxide in the feed reacts with part of the hydrogen in the feed to produce methanol; (ii) part of the carbon monoxide in the feed reacts with at least part of the dimethyl ether in the feed to produce methyl acetate; and (iii) part of the hydrogen in the feed reacts with at least part of the methyl acetate produced in (ii) to produce an effluent comprising methanol and ethanol. At least part of the ethanol is recovered from the effluent and at least part of the methanol is dehydrated to produce dimethyl ether, which is recycled to the reaction zone.

CATALYST COMPOSITION FOR ISOMERIZATION OF PARAFFINS

A catalyst composition for isomerization of paraffins includes at least one metal, at least one heteropoly acid and a support material. Further provided are a process for preparation of the catalyst composition and a process for isomerization of paraffins using the catalytic composition.

Syngas conversion catalysts are H-MOR catalysts including iron and zinc. The catalysts can be made using a solid-state ion exchange process. The catalysts can be used in DSTO processes.

CATALYTIC CONVERSION OF SYNGAS TO LIGHT PARAFFINS

There is provided a catalyst for the conversion of syngas to light paraffins. The catalyst includes a first catalytic component comprising carbon and/or at least one oxide of at least one element selected from the group consisting of copper, zinc, and aluminum, and a second catalytic component comprising at least one zeolite selected from the group consisting of ferrierite, mordenite, theta-1, ZSM-5, H-beta, H-Y and ZSM 23. The first catalytic component and the second catalytic component are present in a weight ratio of from 90:10 to 50:50 respectively.
