    • The methanol vapor is mixed with a gas mixture which consists mainly of carbon dioxide and hydrogen and a high-methanol mixed feedstock is thus obtained. The mixed feedstock is fed to a first catalytic breakdown zone at an entrance temperature from 300.degree. to 400.degree. C., which contains a zinc-containing catalyst, which is indirectly heated. An intermediate having a methanol content not in excess of 1% by volume is withdrawn at a temperature in the range from 350.degree. to 600.degree. C. from the first breakdown zone and is cooled. Condensed water is removed at least in part from the intermediate, which is subsequently heated to a temperature in the range from 320.degree. to 420.degree. C. At least one-half of the heated intermediate product is supplied to a second catalytic breakdown zone, which also contains a zinc-containing catalyst, which is indirectly heated. A precursor product is withdrawn from the second breakdown zone at temperature from 350.degree. to 600.degree. C. and is cooled and aqueous condensate is withdrawn from the precursor. The product, which is subsequently supplied at an entrance temperature from 20.degree. to 80.degree. to and is passed through a separating zone, which contains a multiplicity of selectively permeable membranes. First and second gas streams are withdrawn from the separating zones. The first gas stream contains at least 90% by volume CO.sub.2 and H.sub.2. The second gas stream contains at least 30% by volume CO. The first gas stream is enriched with CO.sub.2 to provide a gas mixture, which is mixed with the methanol vapor.

The reactor includes a substantially cylindrical outer shell which is provided at opposite end faces with a gas inlet and a gas outlet. An inner vessel contains part of the catalyst volume for the reactor which is impermeable to gas adjacent to the gas inlet. The inner vessel has a substantially cylindrical shell which defines a flow passage with the inner surface of the outer shell of the reactor and has openings for the radially inward passage of the gas mixture to be reacted. A perforated central gas-collecting tube containing no catalyst is positioned in the inner vessel and one or preferably two additional catalyst beds are positioned between the inner vessel and the gas outlet.
