【Abstract】 On the basis of FCC techniques, a series of new technologies and special catalysts for the production of light olefins from heavy oils were researched and developed. The technological test results and differences of the DCC-I, MGG, ARGG, DCC-Ⅱ, MIO as well as CPP processes were presented. It is proposed that, according to the properties of feedstocks and the market requirements, the maximum yield of end products can be obtained by using whichever above-mentioned process and the corresponding catalyst with appropriate revamping the existing FCCU.更多还原
