| Abstract: | The catalytic cracking of heavy oil was studied using a SO 2- 4/ZrO 2 superacid system as catalyst promoter in a fixed fluidized bed reactor. It was shown that the suitable amount of SO 2- 4/ZrO 2 could increase the yield of light oil and reduce coke formation. In the presence of steam, the Bronsted acid of the SO 2- 4/ZrO 2 superacid system plays an important role on the catalytic cracking of heavy oil. |
