FF-46加氢裂化预处理催化剂的开发与应用

摘要

In order to meet the requirement of processing high nitrogen and sulfur feedstocks, a new generation of hydrocracking pretreatment catalyst,FF-46,was developed by Fushun Research Institute of Petroleum and Petrochemicals. FF-46 catalyst having Mo-Ni active metal components was prepared by complexation technology and the acidity of its support was well adjusted. Lab evaluation results showed that the catalytic activity of FF-46 catalyst was significantly better than those of other catalysts including an industrial reference catalyst. FF-46 catalyst was applied in several hydrocracking units successfully. The industrial application results showed that FF-46 catalyst exhibited high HDN and HDS activities, it can meet the requirement of long-term operation.%为了满足加氢裂化装置加工硫、氮等杂质含量高的原料的需要,中国石化抚顺石油化工研究院采用Mo、Ni为活性金属组分,通过合适的助剂降低载体表面的强酸量,使用络合技术负载活性金属,研制出新一代具有高加氢脱氮活性的加氢裂化预处理催化剂FF-46,并在中国石化镇海炼化分公司等单位的加氢裂化装置上实现工业应用.实验室小型装置评价结果表明,FF-46催化剂的活性明显优于其它技术制备的催化剂,同时也优于工业参比剂；工业应用结果表明,FF-46催化剂的脱硫、脱氮活性高,能够满足装置长周期运转的要求.
