<p>PURPOSE:To form monoolefins with high activity and selectivity by depositing palladium (1) and >=1 kind of metal (2) selected from ruthenium, rhodium, cobalt, rhenium, or their oxides on a carrier. CONSTITUTION:A soln. of metallic compds. as catalyst components of palladium and >=1 kind selected from ruthenium, rhodium, cobalt, and rhenium in water, hydrochloric acid, nitric acid, or aliphatic carboxylic acid is prepared. After a carrier is immersed in said catalyst component soln., the solvent is evaporated by heating, or removed by decantation, etc. Consequently, the catalyst components are adsorbed by the carrier, and the carrier deposited with catalyst components is dried at 100-300 deg.C for 1-24hr to obtain the titled catalyst. 0.05- 2wt% palladium metal is preferably deposited on the carrier, and 0.05-1wt% promoter metal is preferably deposited.</p> |
