A carbonylation process in the presence of a pretreated zeolite catalyst which comprises the sequential steps (i) pretreating the catalyst and (ii) carbonylating dimethyl ether with a carbon monoxide-containing gas to produce methyl acetate in which the catalyst pretreatment step (i) comprises a step (a) contacting the catalyst with a first treatment mixture comprising water vapour; and a step (b) contacting the treated catalyst of step (a) with a second treatment mixture comprising an inert gas and at least one of dimethyl ether and methanol.

Carbonylation process using a pretreated zeolite catalyst

Crystalline zeolites having a FER framework type wherein the crystallites have a dimension in the c-axis of about 500 nanometers (nm) or less, a method for their preparation and a process for the co-production of acetic acid and dimethyl ether comprising the step of contacting methyl acetate and methanol in the presence of catalysts comprising the crystalline zeolites.

Dehydration-hydrolysis processes and catalysts therefor

Process for the co-production of acetic acid and dimethyl ether by contacting methyl acetate and methanol in the presence of a catalyst containing a crystalline zeolite having a FER framework type. The zeolite has crystallites having a dimension of about 500 nm or less in the c-axis.

Process for treating an alcohol composition containing nitrogen-containing contaminants by contacting the alcohol composition with an adsorbent in an adsorption zone. The adsorbent is a transition metal-loaded solid porous material selected from aluminosilicates, silica-aluminas, silicates and aluminas, and the alcohol composition is contacted with the adsorbent either alone or in the presence of an inert carrier gas.

Treatment of alcohols

Process for the carbonylation of dimethyl ether with carbon monoxide in the presence of a catalyst to produce methyl acetate reaction product.
