Abstract
A process for the preparation of methanol having the process a carbon oxides per-pass conversion equal to or higher than 65%, and a selectivity to methanol formation equal to or higher than 75% by submitting carbon dioxide, carbon monoxide or a mixture of carbon monoxide and carbon dioxide to a hydrogenation reaction using a specific metal compound and specific reaction conditions of temperature, pressure, space velocity and a specific range of molar ratio of hydrogen to carbon dioxide, of hydrogen to carbon monoxide, or of hydrogen to the mixture of carbon monoxide and carbon dioxide. It further relates to a process for converting the methanol obtained into dimethyl ether or into a mixture of (C2-C8)alkene and (C1-C8)alkane.
