Integrated process for the production of methyl acetate and methanol. The process is carried out by carbonylating dimethyl ether with synthesis gas and recovering methanol and unreacted synthesis gas. The recovered synthesis gas is utilized as the sole fresh synthesis gas for methanol synthesis.

Integrated process for the production of methyl acetate and methanol from synthesis gas and dimethylether

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.
