摘要
对 Ｓ Ｏ２－４ ／ Ｚｒ Ｏ２ 超强酸体系作为重油催化裂化助剂进行了研究。结果表明，加入适量的 Ｓ Ｏ２－４ ／ Ｚｒ Ｏ２ 可提高轻质油收率，并能降低催化剂生焦；在工业催化裂化高温水蒸汽流化的条件下， Ｓ Ｏ２－４ ／ Ｚｒ Ｏ２ 超强酸体系中的 Ｂ 酸对重油催化裂化起着至关重要的作用。
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.
