【摘要】 常压下,在265～295℃温度范围内,用内循环无梯度反应器对甲基叔丁基醚(MTBE)在CRN型活性炭催化剂上裂解制异丁烯的反应动力学进行了研究。研究结果表明,裂解反应由吸附的MTBE生成非吸附产物的不可逆表面反应所控制,其本征动力学方程为 (-r_A)=κP_A/(1+κ_AP_A)式中κ=2.6167×10~9 exp(-1.4730×10~2/RT) κ_A=8.6829×10~6 exp(-1.1661×10~2/RT)更多还原

【Abstract】 Under normal pressure and 265～295℃, the kinetics of cracking methyl tert-butyl ether (MTBE) into isobutene on activated Carbon catalyst was studied. Results show that the reaction is controlled by irreversible surface reaction which implies the adsorbed MTBE cracked into unadsorbed product. The kinetic equation is:(-r_A)=κP_A/(1+κ_AP_A)where κ=2.6167×10~9exp(-1.473×10~2/RT)κ_A=8.6829×10~6exp(-1.1661×10~2/RT)更多还原
