Abstract: 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.
