进行了柴油加氢装置掺炼沸腾床渣油加氢装置生产的柴油馏分(简称沸腾床加氢柴油),生产满足GB19147—2016车用柴油(Ⅴ)标准(国Ⅴ车用柴油标准)柴油的可行性研究。结果表明,常规柴油加氢装置掺炼一定比例的沸腾床加氢柴油馏分,可以生产出国Ⅴ车用柴油调合组分;直馏柴油掺炼30%沸腾床加氢柴油,在反应压力6.5MPa、体积空速1.5h~(-1)、反应温度360℃、氢油体积比500的条件下,精制柴油满足国Ⅴ车用柴油标准;混合柴油(直馏柴油、焦化柴油和催化裂化柴油的质量比为62∶25∶13)掺炼30%沸腾床加氢柴油,在反应压力7.3 MPa、体积空速1.0h~(-1)、反应温度355℃、氢油体积比500的条件下,可以生产出硫含量满足国Ⅴ标准的车用柴油调合组分。本研究结果可为沸腾床加氢柴油馏分的加工路线提供理论依据。

FEASIBILITY STUDY OF PRODUCING NATIONAL V DIESEL BY BLENGDING EBULLATED-BED RESIDUE HYDROCRACKING DIESEL DISTILLATE IN DIESEL HYDROTREATING UNIT

The feasibility of producing China V diesel (GB 19147-2016) by processing feed blending ebullated-bed residue hydrocracking diesel distillate was studied. The experimental results showed that the phase V diesel component can be obtained by blending a certain proportion of hydrocracking diesel distillate from ebullated-bed process. When SR diesel blending 30% ebullated-bed hydrocracking diesel is used as feed, the refined diesel oil can meet the national standard V at conditions of 360℃, 6.5 MPa, Sv = 1.5h-1, H2/oil of 500(v); when hybrid diesel blending 30% ebullated-bed hydrocracking diesel fraction as feed, at conditions of 355℃, 7.3 MPa, Sv = 1.0h-1, and H2/oil of 500, the national standard V diesel component can be obtained. The research results provide a theoretical basis for the processing of the ebullated-bed hydrocracking diesel.
