CARBON MONOXIDE CONVERSION PROCESS AND REACTOR

摘要

Process and reaction unit for isothermal shaft conversion of a carbon monoxide containing feed gas, the process com- prising the steps of introducing the feed gas in a reaction unit into reactor tubes with a fixed bed of a shift conversion catalyst in a reaction zone; contacting the feed gas with the catalyst at conditions be- ing effective in carbon monoxide shift conversion reaction with steam reactant to hydrogen and cooling the reaction by indirect heat exchange with a cooling agent by passing the cooling agent in a falling film along shell side of the re- actor tubes and removing heated coating agent from the fal- ling film; passing hydrogen when it is formed by the shift conversion reaction through a hydrogen selective membrane to a perme- ate zone withdrawing hydrogen from the permeate zone arid carbon mon- oxide depleted feed gas from the reaction zone.
