摘要
中国石油大港石化公司300 kt／a催化重整装置使用进口的DN-200加氢处理催化剂,在反应压力2.20 MPa、反应温度290℃条件下,对掺有质量分数为18％的重油催化裂化汽油与直馏汽油的混合油进行预加氢精制,使混合原料油中的硫含量由50-70 μg／g、氮含量由8-1 μg／g,均降低到小于0.5 μg／g,满足了工艺要求,为扩大催化重整装置的原料来源提供了有用的信息。其中操作的关键在于将混合原料的终馏点控制在172℃以下(90%的馏出点控制在148 ℃左右)。
The imported DN-200 hydrotreating catalyst has been applied in the 300kt/a reformer of Dagang Petrochemical Company for processing straight-run gasoline blended with 18 wt% heavy oil FCC naphtha. Under the operating conditions of a reaction pressure of 2. 20MPa and a reaction temperature of 290℃, the sulfur and nitrogen contents in the mixed feedstock reduced from 50-70 μg/g and 8-16μg/g to both less than 0. 5 μg/g respectively after pre-hydrotreating, which met the process requirement. The key factor of operation was controlling the end point of the feedstock lower than 172℃ with a 90% point around 148℃.
