PURPOSE: To improve a dehydrogenation performance of hydrocarbon by depositing a platinum group metal and zinc being a catalyst component on a carrier consisting of a silicalite structure whose basic structural unit is silicon and oxygen or silicon, zinc and oxygen. CONSTITUTION: The dehydrogenation catalyst is produced by depositing the platinum group metal and zinc being the catalyst component on the carrier being the silicalite structure whose basic structural unit is the silicon and oxygen or silicon, zinc and oxygen. In the platinum group metal being the catalyst component, there is Pt, Ru, Ir, Rh and Pd, and Pt is suitable, and a deposited amount on the carrier is less than 5 wt.% expressed in terms of metal, and 0.01-2 wt.% is more suitable. The deposited amount of Zn being the catalyst component is 0.05-20 wt.% appropriately. An alkene product is obtained by allowing 2C-10C paraffin to contact with the dehydrogenation catalyst. |
