本文介绍了在375℃和450℃,气体中H_2S含量很低的情况下,采用大空速及小粒度催化剂,以消除内、外扩散的影响,于触媒催化活性稳定期中,改变空速和原料气的组成,以直流法微分反应器测得常压下J_(p-2)催化剂的正反应动力学方程式为; [克分子/克催化剂·时]其中并于400℃条件下,在离平衡不太远的情况和积分反应器中验证了方程的适用性,同时测得了正反应表观活化能:E=27070(卡/克分子)。 This article describes the use of large space velocity and small particle size catalysts at 375 ° C and 450 ° C with low H2S content to eliminate the effects of internal and external diffusion and to change the space velocity and feed gas The reaction kinetics equation of J_ (p-2) catalyst under atmospheric pressure was measured by direct current microreactor under the condition of [mol / g catalyst · h] Too far the situation and the integral reactor to verify the applicability of the equation, while measuring the apparent activation energy of positive reaction: E = 27070 (cal / mol).
