CATALYST FOR PRODUCTION OF HIGH CALORIE GAS AND ITS PRODUCTION

摘要

PURPOSE: To produce a catalyst having superior mechanical strength, excellent in resistance to poisoning by sulfur and the deposition of carbon, hardly reducing its activity over a long time and capable of efficiently producing high calorie gas. CONSTITUTION: Carrier stock contg. aluminum hydroxide (a), at least one kind of metal oxide (b) selected from among oxides of groups II and III metals and lanthanoids and a combustible high molecular compd. (c) is molded into a carrier substrate and fired to form an activated alumina composite carrier. The amt. of the metal oxide (b) is 5-30wt.% of the amt. of the resultant catalyst. Ruthenium is then deposited on the carrier and reduced to produce the objective catalyst.
