  • Process for the manufacture of methanol in combination with steam reforming of light hydrocarbons
    Patent number: 4894394
    Abstract: Process for the manufacture of methanol by the reaction of a carbon monoxide and hydrogen mixture obtained by steam reforming of light hydrocarbons in the liquid phase in the presence of the catalyst system obtainable by combination of at least:(a) the salt containing a cation of a metal of group VIII of the Periodic Table of the Elements,(b) an alcoholate from an alkaline metal or alkaline earth metal, in a single pass through reactor, by conversion of the hydrogen-carbon monoxide gas mixture, which has been treated after steam treatment of natural gas by scrubbing carbon dioxide from the obtained gas mixture, and which has a hydrogen-carbon monoxide molar ratio in the range of from 2.8-4.5, and using the off-gas from the reaction after recovery of methanol as fuel to the reformer furnace.
