摘　　要：以加氢柴油为原料,选取催化裂化加工过程中常用的重油催化剂和多产丙烯催化剂,考察了加氢柴油在这两种类型催化剂上催化裂化时产物分布和产品性质的差异。实验结果表明,加氢柴油在重油催化剂有着更高的转化率和目的产物收率;但在多产丙烯催化剂上,产物选择性更优,并且氢转移反应得到减弱,液化气及汽油产品中烯烃含量升高;此外,相比于多产丙烯催化剂,重油催化剂上获得的汽油产品有着更高的芳烃含量,并且在未转化柴油组分中,饱和烃及单环芳烃含量显著降低,体现出重油催化剂对烃类较高的裂化性能。Catalysts for heavy oil cracking and maximizing propylene production were selected, and the distribution and property differences of products from hydrotreated light cycle oil（HLCO） catalytic cracking over these two kinds of catalysts were investigated. The results showed that, using the heavy oil cracking catalyst, HLCO conversion and target products yield were improved. However, the catalyst of maximizing propylene production had superior product selectivity, and the hydrogen transfer reaction during HLCO catalytic cracking was suppressed. As a result, the olefins contents in liquefied petroleum gas（LPG） and gasoline increased. In addition, compared with the catalyst of maximizing propylene production, the gasoline product obtained by using the heavy oil cracking catalyst possessed higher aromatics content, and saturated hydrocarbon and mononuclear aromatics content in unconverted light cycle oil decreased, which indicated the strong catalytic cracking ability of the heavy oil cracking catalyst for hydrocarbons.
