Carbon monoxide-chromium

Catalysts which have been heated for one hour at 250°C. with carbon monoxide at 100 mm., cooled to 35°C., and pumped to remove physically adsorbed gas have far greater activities than untreated catalysts at all chromium concentrations (7). At low pressures, CO treatment increases the activity by at least an order of magnitude. As described in a previous publication, on the basis of infrared evidence, it is believed that the CO-treated catalyst is characterized by the presence of a carbon monoxide-chromium complex.
