摘要
采用分步浸渍法制备了一系列NiMoP/γ-Al_2O_3催化剂,并用电感耦合等离子体光谱、N_2吸附脱附、透射电镜、H_2程序升温还原等技术对NiMoP/γ-Al_2O_3催化剂进行了表征。在固定床反应器中,进行了模型化合物的加氢实验,确定了催化剂活性组分Ni的最佳含量(4%,质量分数),将最佳Ni含量的催化剂用于实际的煤焦油加氢研究,并对比分析了酚油的切除对加氢效果的影响,结果表明,酚油的切除可以促进S、N原子的脱除以及芳烃的饱和。
The NiMoP/γ-Al2O3 catalyst was prepared through a multi-step impregnation method and characterized by inductively coupled plasma mass spectrometry ( ICP-MS ) , N2 adsorption-desorption, transmission electron microscope ( TEM ) and H2 temperature programmed reduction ( H2-TPR ) . The catalyst with 4% Ni is determined to be the best one with optimum component proportion by the tests with model compounds in a fixed-bed reactor. The coal tar hydrogenation was conducted over the optimum catalyst. The results reveal that the removal of carbolic oil can promote the removal of S and N and the saturation of aromatics.
