摘要
在等温积分反应器中进行了氨和苯的浓度阶跃瞬态响应实验。根据瞬态响应结果,认为苯以气相苯形式与催化剂上吸附态氧进行反应,并判明该催化氧化反应有中间产物生成的机理。
Systematic study on heterogeneous catalytic oxidation reaction of benzene to malcic anhydride over V_2O_5 catalyst by transient response method was made. In an isothermal integral reactor, through the combined step-up and step-down transient response experiment of benzene specifically designed, conclusion was reached that benzene in gaseous state takes part in the reaction, oxygen is adsorbed on the surface of the catalyst and some inter mediates are formed during the reaction.
