Device for reducing carbon monoxide in a reformate stream

摘要

A methanation reactor to reduce carbon monoxide concentration in a reformate stream. The reactor includes a noble metal catalyst supported by a ceramic support such that the reactor preferentially converts of carbon monoxide via methanation over that of carbon dioxide. In one embodiment, the ceramic support is alumina with a coating of silica deposited on the alumina to increase the support surface acidity and consequent carbon monoxide conversion. The purpose of the abstract is to enable the United States Patent and Trademark Office and the public generally to determine from a cursory inspection the nature and gist of the technical disclosure, and is not to be used for interpreting the scope of the claims.
