| Abstract: | To improve the heavy oil emulsification of fluid catalytic cracking(FCC)feedstock and decrease the carbon deposition and the yield of dry gas,the oil was emulsified.The factors influencing the emulsification including selection and composition of the emulsifiers and the process conditions were studied.The results showed that S_1(Span-40)and S_1-O_3(OP-10)binary and S_1-O_3-T_2(Tween- 60)ternary emulsifiers could meet the requirements with the stability time of more than 9 days.The proper emulsification conditions were found as follows,emulsifying temperature 70-80℃,10% wa- ter content,0.75%-1.0% emulsifier and emulsification time 40 min. |
| Keywords: | fluid catalytic cracking feedstock heavy oil emulsifier emulsifying conditions |
