介绍了LY-C2-02碳二后加氢催化剂在中国石油兰州石化公司24万t/a乙烯装置和中国石油辽阳石化公司20万t/a乙烯装置上的应用情况。结果表明,在兰州石化公司装置,一、二、三段反应器除炔量分别为0.63%,0.47%,0.17%;温升分别为31.8,28.9,15.9℃;3段反应器催化剂寿命均超过3年。在辽阳石化公司装置,当一段反应器入口物料中乙炔的体积分数为1.9%～2.5%时,平均总选择性为43%;一、二段反应器平均除炔量分别为1.85%,0.35%;温升分别为76.4,23.1℃;预计2段反应器催化剂寿命可超过3年。
The application of LY-C2-02 carbon two post-hydrogenation catalyst to 240,000 t / a ethylene unit of PetroChina Lanzhou Petrochemical Company and 200,000 t / a ethylene unit of PetroChina Liaoyang Petrochemical Company was introduced. The results showed that the acetylene removal rates of the first, second and third reactors of Lanzhou Petrochemical Company were 0.63%, 0.47% and 0.17% respectively; the temperature rise was 31.8, 28.9 and 15.9 ℃ respectively; 3 years. In the Liaoyang Petrochemical Company plant, when the volume fraction of acetylene in the inlet of a reactor reaches 1.9% ~ 2.5%, the average total selectivity is 43%. The average removal rates of acetylene in the first and second reactor are respectively 1.85%, 0.35% ; The temperature rise is respectively 76.4,23.1 ℃; It is estimated that the catalyst life of the second-stage reactor can exceed 3 years.
