WIPO Patent Application WO/2018/193668
Kind Code:
A1
Abstract:
This unsaturated hydrocarbon production method includes: a dehydrogenation step of obtaining a gas comprising at least one type of unsaturated hydrocarbon selected from the group consisting of an olefin and a conjugated diene that is generated by bringing a raw material gas containing at least one type of hydrocarbon, selected from the group consisting of an alkane and an olefin, into contact with a dehydrogenation catalyst, containing a group 14 metal element and Pt; and a regeneration step of bringing the dehydrogenation catalyst that was used in the dehydrogenation step into contact with a regenerating gas containing molecular oxygen, under a temperature condition of 310 to 450°C.
