Embodiment Construction
[0016] The raw material used in the present invention is full cut FCC gasoline, wherein the olefin content and sulfur content are≯50v%,≯1000μg / g. The olefin content of the produced oil is less than 20(v)%, the sulfur content is less than 200 μg / g, and the antiknock index (R+M) / 2 loss is less than 1.0 unit.
[0017] The raw materials used are listed in Table 1. The first reaction zone uses the commercial hydrorefining catalyst FH-98 produced by Wenzhou Huahua Group Company. The second reaction zone uses a selective hydrodesulfurization catalyst. The third reaction zone uses a gasoline upgrading catalyst.
