PRODUCTION OF CARBON MONOXIDE

摘要

PURPOSE: To efficiently obtain carbon monoxide when carbon monoxide is produced by bringing carbon dioxide and hydrogen into contact with a catalyst by using a metallic multiple oxide containing iron oxide prepared by spray decomposition method as the catalyst. CONSTITUTION: An iron compd. such as iron nitrate and iron sulfate, a chromium compd. such as chromium nitrate and chromium sulfate, an aluminum compd. such as aluminum nitrate and aluminum sulfate are dissolved in a solvent such as water and alcohol to prepare the source soln. Then the source soln. is sprayed into a carrier gas flow to produce liq. drops. The produced liq. drops are carried by the carrier gas and introduced into a heating furnace where the drops are decomposed and calcined to obtain a catalyst having high activity comprising a metallic multiple oxide containing iron oxide, chromium oxide and aluminum oxide. Then carbon dioxide and hydrogen are brought into contact with the obtd. catalyst to produce carbon monoxide. This catalyst has a high conversion rate even at high temp. and does not decrease in the activity but maintains its high activity. Thus, carbon monoxide can be efficiently produced.
