PROCESS FOR PYROLYSIS OF HYDROCARBON |
摘要 |
The present invention relates to a process for pyrolysis of hydrocarbons for olefin preparation, and particularly to a process for pyrolysis of hydrocarbons comprising pyrolyzing paraffin hydrocarbons in the presence of steam to prepare olefins, where the pyrolysis is conducted in a pyrolysis reaction tube in which a porous inorganic substance with a pore diameter of 1 µm SIMILAR 5 mm, a porosity of 10 SIMILAR 80%, and a maximum specific surface area of 0.1 m<2>/g is inserted or filled. According to the present invention, in the hydrocarbon pyrolysis process, the porous inorganic substance is inserted or filled into the pyrolysis reaction tube, and thus the olefin yield can be improved compared to the conventional pyrolysis processes, a continuous operation period can be prolonged, and a life cycle of the pyrolysis reaction tube can be prolonged
