Embodiment 1
[0038] Datang low-temperature coal tar is used as raw material, and the cut point is 500°C. The specific properties are shown in Table 1. The hydrogenation protection catalyst FZC-103 and the hydrofinishing catalyst 3936 are filled in the hydrotreatment reaction zone, and the filling volume ratio of the hydrogenation protection catalyst FZC-103 and the hydrofinishing catalyst 3936 is 1:4. The hydrogenation upgrading reaction zone is filled with FTX catalyst and FC-28 catalyst, and the loading volume ratio is 1:1. The hydrogenation supplementary refining reaction zone is filled with hydrofining catalyst FV-10. The process conditions and product properties of the hydrogenation process are shown in Table 2 .
