根据在小型同轴催化裂化装置上的试验结果,得出由于加入酸性助剂引起催化剂中B酸活性与L酸活性的比例发生变化,可以提高轻质油收率,同时证明,在催化裂化反应过程中B酸起主导作用. According to the test results on a small coaxial catalytic cracking unit, it is concluded that the ratio of the B acid activity to the L acid activity in the catalyst is changed due to the addition of an acid aid, thereby improving the yield of light oil. At the same time, it was proved that in the catalytic cracking reaction B acid plays a leading role in the process.
