Embodiment 1-4 and comparative example 1
[0028] See the flowchart of Examples 1 to 4 figure 1 , The comparative example is that the coking whole distillate raw material directly enters the hydrorefining reaction zone without fractionation. The hydrorefining catalyst is filled with a hydrogenation protective agent, and its filling volume is 20% of the volume of the hydrorefining catalyst. The subsequent process is the same figure 1 .
[0029] The hydrorefining catalyst used in the examples and comparative examples is FH-98 (FH-98 is the catalyst grade) produced by the Wenzhou Catalyst Plant developed by Fushun Petrochemical Research Institute, and the hydrocracking pretreatment catalyst is Fushun Petrochemical Research Institute Developed 3996 (3996 is the catalyst grade) produced by Fushun Petrochemical Company Catalyst Plant. The hydrogenation protective agent is FZC-102 (FZC-102 is the catalyst grade) produced by the pilot base of Fushun Petrochemical Research Institute. The hydrogenation protective agent is filled i...
