【摘要】 以蒽为稠油多环芳烃模型化合物,在反应温度400℃、CO初压2 MPa、CO/H₂O（物质的量比）为1∶2.5条件下,用高压反应釜考察了不同反应时间下反应体系中环烷酸盐对蒽富存CO水热变换新生氢的影响,并对环烷酸镍和环烷酸铁复配盐在反应过程中的作用进行了分析。结果表明:环烷酸铁和环烷酸镍对CO水热变换和蒽加氢反应均有催化作用,但环烷酸镍更有利于促进CO水热变换反应,而环烷酸铁对蒽加氢反应的催化作用更强;环烷酸盐单独作用时,当加入环烷酸盐中镍质量分数为0.08%、铁质量分数为0.05%时,各自对蒽加氢反应的催化效果最好;环烷酸铁与环烷酸镍复配对CO水热变换和蒽加氢反应可起到协同催化作用,能够促进CO水热变换反应和蒽加氢反应。研究表明,CO水热变换与蒽加氢反应之间存在正协同效应,二者相互促进。更多还原

【Abstract】 The effect of nickel and iron naphthenate on anthracene hydrogenation by using in situ hydrogen generated through the water gas shift reaction was investigated in an autoclave.The factors of the concentration of nickel and iron naphthenate each,the mixed system of iron and nickel naphthenate were tested.The reaction conditions are follows:400 ℃,2.0 MPa CO,and CO/H₂O molar ratio of 1∶2.5.The reaction samples were took out at different reaction time and analyzed.The results showed that iron and nickel naphthenate are catalytic active for both anthracene hydrogenation and water gas shift reaction.Nickel naphthenate is more conducive to the water gas shift reaction,while the catalytic effect of iron naphthenate on anthracene hydrogenation is more effective.The conversion of anthracene hydrogenation is the highest when the mass fraction of Ni in nickel naphthenate is 0.08% and Fe in iron naphthenate is 0.05% .There is a synergistic effect of iron and nickel naphthenate,which can effectively promote the reactions of the water gas shift and anthracene hydrogenation.Addition,the results indicated that there is a positive synergy between these two reactions.更多还原
