摘　　要：为解决某炼化企业劣质催化柴油大量过剩的问题,计划对装置进行改造,适当降低装置加工量,以满足加工催化柴油的需求。为确认方案的可行性,在加氢中试装置进行了可行性试验。结果表明,对低压加氢装置进行改造后,可以满足处理催化柴油的要求;在反应压力4.0 MPa、平均反应温度350℃、体积空速0.55 h^(-1)、氢油体积比300的条件下,精制柴油硫含量可以满足国Ⅵ标准柴油调和组分的要求。In order to solve the problem of excess of inferior catalytic diesel in a refinery enterprise,it is planned to transform the unit and appropriately reduce the processing volume of the unit to meet the needs of catalytic diesel processing.In order to confirm the feasibility of this scheme,conducted a feasibility test study in a hydrogenation pilot plant.The experimental results show that the modified low pressure hydrogenation unit can meet the requirements of catalytic diesel.Under the conditions of reaction pressure 4.0 MPa,average reaction temperature 350℃,volume space velocity 0.55 h^(-1)and hydrogen-to-oil volume ratio 300,the sulfur content of refined diesel can meet the requirements of national standard VI diesel blending components.
