摘要
On October 15,2020,the new-generation olefin catalytic cracking(OCC)technology developed by the SINOPEC Shanghai Research Institute of Petrochemical Technology(SRIPT)has been successfully applied in the 90 kt/a OCC unit owned by the Lianhong New Materials Science Co.,Ltd.At present,the OCC unit has been running smoothly,while the reactor operates at a load of 108%,with the yields of ethylene and propylene exceeding the contract specified targets.The OCC technology is a new process that can convert the C4/C5 olefins into ethylene and propylene to carve out an important route for increasing the ethylene and propylene production.In addition to its application in the coal chemicals field,the OCC technology can be adopted in the chemical-type petroleum refinery to provide solutions for increasing the olefin yield from the steam cracking unit,which would have a broad application prospect.
