The manufacture method of the alkene of the present invention and monocyclic aromatic hydrocarbon has：Bicyclopentadiene removes treatment process, in this operation, remove the bicyclopentadiene class with bicyclopentadiene skeleton from raw oil, above-mentioned raw materials oil is the thermal cracking mink cell focus obtaining with ethylene manufacture device, and distill 90 capacity % recovered (distilled) temperatures of character and be less than 390 DEG C；And cracking reforming reaction operation, in this operation, make by with bicyclopentadiene removal step process above-mentioned raw materials oil part or all thus the raw oil that bicyclopentadiene class is adjusted to below 10 weight % is contacted with catalyst, reacts, thus obtain comprising alkene, the product of monocyclic aromatic hydrocarbon. |
