| titleOfInvention | A kind of method being prepared divinyl by chain hydrocarbon |
| abstract | The present invention relates to a kind of preparation method of divinyl, the method comprises: (1) is under the existence of cyclization catalyst, raw material containing chain hydrocarbon is carried out cyclization, and obtain the hydrocarbon mixture containing hexa-atomic cyclic hydrocarbon, described chain hydrocarbon is at least one in the alkene of C1-C35 paraffinic hydrocarbons and C2-C35; (2) under the existence of hydrogenation catalyst, the described hydrocarbon mixture containing hexa-atomic cyclic hydrocarbon is carried out hydrogenation reaction, obtains the hydrocarbon mixture containing hexanaphthene and/or alkyl cyclohexane; (3) the described hydrocarbon mixture containing hexanaphthene and/or alkyl cyclohexane is carried out steam cracking reaction as at least part of cracking stock.The preparation method of divinyl according to the present invention can obtain higher butadiene yield, and the yield of methane is lower, and the ice chest energy consumption in splitting gas sepn process is reduced. |
