The invention relates to a catalyst system and process for preparing dimethyl ether from synthesis gas as well as the use of the catalyst system in this process.

Catalyst system and process for preparing dimethyl ether

The invention relates to a catalyst and catalyst layer and process for preparing dimethyl ether from synthesis gas or methanol as well as the use of the catalyst or catalyst layer in this process.

Catalyst and process for preparing dimethyl ether

Process for the in-situ regeneration of a zeolite catalyst in a carbonylation process for the production of at least one of methyl acetate and acetic acid. The process is carried out by (a) contacting a carbonylatable reactant selected from methanol, dimethyl ether and dimethyl carbonate and carbon monoxide in a reactor with a zeolite catalyst and recovering a product stream containing at least one of methyl acetate and acetic acid from the reactor, (b) ceasing contact of the catalyst with the carbonylatable reactant, (c) regenerating the catalyst with a regenerating gas selected from hydrogen or a mixture of hydrogen and carbon monoxide at a temperature in the range 250 to 600 C, and (d) terminating the hydrogen regenerating step and resuming contact of the catalyst with the carbonylatable reactant and carbon monoxide.

Regeneration of zeolite carbonylation catalysts

Process for preparing an aliphatic carboxylic acid having (n+1) carbon atoms, where n is an integer up to 6, and/or the ester derivative thereof by contacting an aliphatic alcohol having n carbon atoms and/or a reactive derivative thereof selected from dialkyl ether, ester of the alcohol and an alkyl halide with carbon monoxide in the presence of a catalyst. The catalyst consists of mordenite which has been ion- exchanged or otherwise loaded with silver.
