| titleOfInvention | A kind of steam cracking method |
| abstract | A kind of steam cracking method, the method comprises: mixed with water vapour by liquid cracking stock, then be heated in convection zone cross-over temperature, enter radiation section afterwards and carry out scission reaction, then the cleavage reaction product obtained is injected quenching apparatus and carry out refrigerated separation, wherein, described method also comprises at least one in following two processes: (1) by heating after cracking stock mixture be added to radiation section before, by heating after cracking stock mixture and olefin; (2) before cleavage reaction product is injected quenching apparatus, cleavage reaction product and olefins contact are reacted.According to described method provided by the invention, by introducing alkene in the exit of radiation section and/or ingress, can not cause producing coking in the convection zone of pyrolyzer and quenching apparatus, and effective utilization of the heat to the high-temperature split product from radiation section can be realized, and improve butadiene yield. |
