Abstract
A reformed hydrocarbon and hydrogen are produced by: subjecting a raw hydrocarbon material to thermal catalytic cracking under hydrogen for dehydrogenation to produce a reformed hydrocarbon having a degree of unsaturation higher than that of the raw hydrocarbon material and hydrogen; introducing the reformed hydrocarbon, hydrogen and an unreacted hydrocarbon into a pressure-reducing-rising device; and reducing and then raising a pressure to facilitate further cracking of the unreacted hydrocarbon and promote liquid-gas separation in a post-step. Hydrogen can be efficiently produced, and a reformed hydrocarbon of good quality (e.g., high octane number) can be produced with suppressing generation of carbon.
