钌催化剂上苯加氢制环己烯的影响因素

Influential factors for selective hydrogenation of benzene to cyclohexene over ruthenium catalysts

综述了钌催化剂上苯选择性加氢的反应机理、催化剂制备过程中前躯体、制备方法、载体、添加剂(水,有机添加剂,无机添加剂)对催化剂催化性能的影响和反应过程中温度、压力、搅拌速率、催化剂用量及反应时间等对苯转化率、环己烯选择性和环己烯收率的影响。

Influential factors for selective hydrogenation of benzene to cyclohexene over ruthenium catalysts and preparation of the catalysts were reviewed, including influence of precursor, preparation methods, carriers and additives (water, organic additives, inorganic additives) on catalytic properties of the ruthenium catalysts, and influence of temperature, pressure, stirring velocity, catalyst loadings and reaction time on benzene conversion, selectivity to and yield of cyclohexene.
