摘要
MGD，a FCC technology that can maximize both the LPG and LCO production,has been developed,The effects of reaction temperature and catalyst to oil ration on naphtha re-craking and the resulted naphtha ompositions were investigated ,The commercial performances show that relative to conventional FCC,the LPG and LCO yields increased by 1.3%-5.0m% and 3%-5m%,respectively. Olefins content in naplhtha decreased by 9%-13v% ,RON and MON of naphtha increased by 0.4-0.7 and 0.4-0.9 units ,respectively.
