Study on the HDM Catalysts for Ni Removal of Ni-TPP; Preparation, Characterization of LaNi1-xCuxO3 Photocatalyst and its Photocatalytic Activity for Water
原油重质化的逐渐加剧产生了两方面的影响。一是渣油产量增加，使得渣油加氢处理技术越来越受到关注；二是渣油中的金属镍和钒杂质含量随之提升，这对于整个加氢处理过程有很多不利的影响。因此，研究镍、钒的脱除机理和方法包括相关催化剂对渣油深加工意义重大。 本文主要研究内容和获得的重要结果如下。 （1）开发一种制备加氢脱金属催化剂的方法，即以氯化铝、碱式碳酸镍和钼酸铵为原料，尿素和碳酸铵为添加剂，通过一步控制组分析出法制备MoNi-Al2O3HDM催化剂。此方法由于无需过滤和洗涤，缩短了制备时间和降低过程成本。研究表明，制备的催化剂具有较好的孔隙率，且Ni、Mo等活性组分分散均匀。 以溶解在液体石...With the vast deposits of heavy crude oils in several parts of the world, it will have a significant impact on two aspects. One is the increasing amount of residua, which makes the hydrotreating process receive more and more attentions; the other is the abundant and undesirable metal Ni and V, which will produce much adverse influences on the hydrotreating process. These trends have emphasized the...学位：工学博士院系专业：化学化工学院_工业催化学号：2062010015362
