在高压液相进料型催化微型反应器-色谱联合装置中,于温度340℃、350℃、360℃、370℃;临氢化压3MPa;催化剂装填量0.1—0.2克:颗粒40—60目;接触时间6—20g·h·mol~(-1);氢烃摩尔比为32:1、29:1、26:1等条件下,得到ZA-2型丝光沸石催化剂上,甲苯歧化反应本征动力学方程为r_J=K·P_J~(0.5),K=3.077×10~6exp(103 320/RT)。反应机理符合L-H的双位吸附机理,表面反应为控制步骤,机理模型为r_J=K_2[K_J P_J/(1+K_J P_J)]~2(式中r_J为甲苯的消耗速率,速度常数K_2=9.196×10~(12)exp(-7460 666/RT)(mol·g~(-1)·h~(-1));吸收常数K_J=1.347×10~(12)exp(623267/RT)(Pa~(-1));P_J为甲苯分压,Pa。
In the high-pressure liquid feed catalytic microreactor - chromatography unit, at a temperature of 340 ° C, 350 ° C, 360 ° C, 370 ° C; Prohydrogenation pressure 3MPa; catalyst loading 0.1-0.2 g: particles 40-60 mesh; The contact time of 6-20g · h · mol -1 and the mole ratio of hydrogen to hydrocarbon of 32: 1, 29: 1, 26: 1, the ZA-2 mordenite catalyst, toluene disproportionation reaction The kinetic equation is r_J = K · P_J ~ (0.5), K = 3.077 × 10 ~ 6exp (103 320 / RT). The reaction mechanism accords with the double-position adsorption mechanism of LH and the surface reaction is the control step. The mechanism model is r_J = K_2 [K_J P_J / (1 + K_J P_J)] ~ 2 (where r_J is the consumption rate of toluene, the rate constant K_2 is 9.196 × 10-12 exp (-7460 666 / RT) (mol · g -1 -1 · h -1); absorption constant K_J = 1.347 × 10-12 exp (623267 / RT) ( Pa ~ (-1)); P_J toluene partial pressure, Pa.
