摘　　要：通过选用清洁、低成本的原材料,创新催化剂制备理念和方法,构建了加氢裂化催化剂清洁生产和低成本制备的技术平台。该技术平台集成清洁法胶溶剂、较高pH、低黏度金属盐溶液和高耐酸性改性分子筛等制备技术,催化剂制备过程中不使用含氮化合物,实现了氨氮和NOx污染物的"零"排放;通过加氢金属活性相物种优选与引入方式的优化研究,使催化剂金属总量和堆密度大幅度降低,比常规方法制备的参比剂分别降低了20.0%和6.5%,单位体积(m3)催化剂原材料成本降低了约3.9万元人民币,降幅约为28%,催化剂制备成本明显降低。催化剂性能评价和稳定性考察实验结果表明,新催化剂和常规催化剂的活性基本相当,产品性质基本一致,新催化剂具有很好的稳定性。A clean process was realized by utilizing low cost,clean raw materials and new idea for hydrocracking catalyst production.This technology platform integrated clean peptizing agent,higher pH,low viscosity metal salt solution and modified molecular sieve resistant to acid.No nitrogen compounds were used during the catalyst preparation,resulting in zero emission of NOxand ammonia nitrogen.By optimizing hydrogenation metal species and the way of introduction,the total amount of metals and the bulk density are reduced by 20.0% and 6.5%,respectively,compared with the reference catalyst.The cost of raw materials is reduced by about$3.9×104/m3 catalyst,a drop of about 28%.The results of catalytic performance evaluation and stability test show that the new catalysts achieve the similar levels to those prepared by conventional methods and have good stability.
