LOW-TONNAGE METHANOL PRODUCTION

摘要

A method is examined for the synthesis of methanol in a three-phase system: a copper-zinc catalyst, a gaseous mixture of hydrogen and carbon oxides, and an inert hydrocarbon liquid. In the system, the liquid phase ensures isothermic synthesis, while a moving catalyst bed creates more complete contact between it and the gaseous mixture. Instead of the existing 4-4.5%, the output of methanol with one-time contact between the gaseous mixture and catalyst is increased to 15-20%. This allows for a reduction in power consumption, and simplification of the process required for the production of methanol, as well development of a small-scale portable plant.
