Title:
UNSATURATED HYDROCARBON PRODUCTION METHOD AND CONJUGATED DIENE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/159570
Kind Code:
A1
Abstract:
A conjugated diene production method according to one aspect of the present invention includes a step for obtaining a generated gas containing at least one type of unsaturated hydrocarbon selected from the group consisting of olefins and conjugated dienes by bringing an alkane-containing feedstock gas into contact with a dehydrogenation catalyst. In this production method, the dehydrogenation catalyst comprises a supported metal containing Pt and a Group 14 metal element supported by a carrier containing Al and a Group 2 metal element. The dehydrogenation catalyst has pores (a) having a pore diameter of 7 nm to 32 nm. The proportional pore volume of the pores (a) is at least 65% of the total pore volume of the dehydrogenation catalyst.
