Embodiment 1
[0024] The catalytic cracking heavy oil is mixed with hydrogen, and then reacted with hydrogenation protection agent, hydrogenation deasphaltenation agent and hydrofinishing agent successively. See Table 3 for the process conditions of catalytic cracking heavy oil hydrogenation and the properties of the produced oil. See Table 4 for the process conditions, product distribution and gasoline properties of the catalytic cracking unit. It can be seen from Table 3 and Table 4 that after catalytic cracking heavy oil is hydrotreated, the resulting oil ΔH (increased hydrogen content) is 1.50%, and the naphthene content is 45.0% by weight. The gasoline yield is 6.25%, the gasoline yield is 57.90%, and the gasoline octane number (RON) is 93.6.
