CHEMICAL PROCESS AND CATALYST

摘要

PURPOSE: To improve a dehydrogenation performance and stability of hydrocarbon by forming the catalyst by depositing a platinum group metal and tin on a silicalite supporting body excluding substantially alkali and alkaline earth metal. CONSTITUTION: The silicalite supporting body excluding substantially the alkali and alkaline earth metal is impregnated with an impregnating liq. in which a soluble and heat decomposable platinum group metal compd. and a soluble and heat decomposable tin compd. are dissolved. Then the dehydrogenation catalyst is formed by depositing the platinum group metal and tin on the supporting body by drying and burning. A deposited amount of the platinum group metal on the supporting body is 0.01-2 wt.% appropriately, and the deposited amount of the tin is 0.1-15 wt.% appropriately. An alkene product is obtained by allowing 2C-10C paraffin to contact with the dehydrogenation catalyst under dehydrogenation condition.
