The invention relates to an apparatus for simultaneously injecting fluids into a plurality of samples of porous media, comprising: a plurality of holders for the samples of porous media, each holder comprising a sleeve and first and second platens, the first platen having an inlet for an injection fluid and the second platen having an outlet for a produced fluid, and the samples of porous media being arranged, in use, in each of the holders such that the first platen and second platen of each holder contact a first and second end of the sample of porous medium respectively, the inlet of each first platen being in fluid communication with an injection line for injecting fluid into the sample of porous medium arranged in the holder, the outlet of each second platen being in fluid communication with a dedicated effluent line for removing fluid produced from the sample of porous medium arranged in the holder, on-line and/or off-line analytical means for analyzing the fluids injected into each of the samples of porous media, on-line and/or off-line means for analyzing the fluids removed from each of the samples of porous media. A method of simultaneously injecting injection fluid into the samples of porous media is also provided.

Apparatus and method for testing multiple samples

Process for the carbonylation of dimethyl ether with carbon monoxide in the presence of a catalyst to produce methyl acetate reaction product. The carbonylation process is conducted in the presence of hydrogen at a molar ratio of hydrogen to carbon monoxide of greater than 1 and the catalyst is a mordenite zeolite prepared from a synthesis mixture comprising at least one organic structure directing agent.

Carbonylation process

Process for the production of methyl acetate by carbonylating dimethyl ether with carbon monoxide in the presence of hydrogen and a zeolite catalyst. The process is carried out with a molar ratio of hydrogen to carbon monoxide of at least 1 and the catalyst has been calcined at a temperature of from about 375&#xb0; C. to about 475&#xb0; C.

Process for preparing methyl acetate by the carbonylation of dimethyl ether with carbon monoxide in the presence of hydrogen and a zeolite catalyst. In a first step, the carbonylation is conducted with a carbon monoxide to hydrogen molar ratio of at least 1 and, in a second and subsequent step, the carbonylation is conducted with a hydrogen to carbon monoxide molar ratio of greater than 1.

Process for the carbonylation of dimethyl ether

A process for the production of acetic acid and/or methyl acetate by the carbonylation of methanol, methyl acetate and/or dimethyl ether with carbon monoxide in the presence of a desilicated mordenite catalyst.

Process for the production of at least one carbonylation product selected from acetic acid and methyl acetate, by carbonylating at least one carbonylatable reactant selected from methanol and reactive derivatives thereof with carbon monoxide in the presence of a catalyst. The catalyst is a mordenite which has been treated with an aqueous ammonium hydroxide solution and has a silica:alumina molar ratio of at least 10:1, and the reactive derivatives are selected from methyl acetate and dimethyl ether.

A process for the production of acetic acid and/or methyl acetate by carbonylating methanol and/or reactive derivatives thereof with carbon monoxide in the presence of a catalyst which is a mordenite which has been treated with an aqueous basic solution containing at least one of aluminate ions and gallate ions and has a silica:XOmolar ratio (wherein X is A1 and/or Ga) of at least 12:1.
