Claim:
1. A method for producing a hydrocarbon material from a C 5 raffinate which is obtained as an extracted residual oil after separating at least part of isoprene by extraction distillation from a C 5 fraction which is produced as a byproduct when thermally cracking naphtha to produce ethylene and has C 5 organic compounds as main ingredients comprising, a gas-phase thermal cracking step of gasifying said C a desulfurization step, after said gas-phase thermal cracking step, of removing at least part of the sulfur-containing ingredients which are contained in the gasified C a hydrogen addition step, after said desulfurization step, of hydrogenating at least part of the carbon-carbon double bonds of at least one selected from diolefins and olefins which are contained in the gasified C wherein said desulfurization step is performed in a reducing atmosphere under conditions of a pressure of 0.3 MPa or less and a temperature of 180 to 400° C.
