A method for the production of carbon monoxide by Reverse or retroconversion adapted with a Catalyst

摘要

A method for the production of carbon monoxide by Reverse or retroconversion in gaseous phaseCarbon Dioxide Gas and hidrogenogaseoso with minimization of methane ProductionWhere the Reaction is performed at a temperature of 300 to 520 * C and under a pressure of 10 to 40 bars the presence of a catalyst based on zinc oxide and Chromium oxide, which contains no iron.This procedure is preferably continuous and comprendepreferentemente stages that consist of: a) preparing a gaseous mixture rich in carbon dioxide and Hydrogen has a TemperTemperatures from 300 to 520 * C; b) reacting the gaseous mixture, with formation of carbon monoxide and water vapourThrough the passage of the mezclagaseosa information through a catalytic Bed of a catalyst based on zinc oxide and Chromium oxide and kept under a pressure of 10 to 40 bars; (c) CoolsR The gas Flow leaving the catalytic bed so d e cause condensation of Part or all of the water vapor formed; (d) separating the Condensed water flow; and (e) llThe Case comes back to process at least once gas Flow resulting previously carried a temperature of 300 to 520 * C, Making the steps (b) to (d) above,So as to increase the proportion of carbon monoxide in the gaseous Flow, and preferably every stage (b) in a different catalytic bed.
