Synthesis of Surfactant Used in Heavy Oil Catalytic Cracking

The surfactant which was applied to catalytic cracking of heavy oil was synthesized.The effects of reaction temperature,reaction time,the mixture ratio of raw material,as well as the input amount of catalyst on acid value and saponifying value of this product were studied.The optimal reaction conditions were determined: Reaction temperature is 135 ℃;time is 3 h;the ratio of raw material is 1∶1.2;w(catalyst) is 0.4%.Intensified FCC shows that the surfactant improves distribution of the product,increased yield of light oil,decreased productivity of coke and dry gas.
