摘要：通过临氢微型反应器中催化剂评价实验,对钯巴含量分别为0.1％、0.2％、0.3％、0.4％、0.5％的Pd/SAPO-11催化剂进行了评价,其裂解率分别为:0.14％、0.25％、0.25％、0.09％、0.03％,说明该系列催化剂对裂解有抑制作用;在考察的范围内,催化剂的活性、选择性、异构化率均随着钯含量的增加而上升;钯含量在0.25％～0.50％时,催化剂稳定性良好,钯含量过低催化剂较易失活。说明在考察的范围内,钯含量为0.5％时具有较好的催化性能:活性64.2％,选择性7.1％,C_5异构化率67.0％,C_6异构化率62.3％。
After tests of isomerization catalysts in the hydro - microreactor, five catalysts of different Pd contents as 0.1%, 0.2%, 0.3%, 0.4%, 0.5% were studied in this paper. The hydrocracking ratios of Pd/SAPO - 11 are0.14%, 0.25%, 0.25%, 0.09%, 0.03%, which indicate that the catalysts can decrease hydrocracking ratios. The conversion ratios, selectivities and isomerization ratios will increase with increasing of Pd contents. The stabilities are good during 0.25 % -0.5% of Pd contents, and the activities soon lose when Pd contents are low. Pd/SAPO -11 of 0.5 % Pd content has the best performances in the five catalysts, whose conversion ratio, selectivity, C5 isomerization ratio and C6 isomerization ratio are 64. 2 % , 7.1%, 67.0%, 62.3% respectively.
