The dehydrogenation of 1-methylcyclohexene (MCHe) and 1-methyl-1,4-cyclohexadiene (MCHde) was studied over an in-house 1.0 wt% Pt/γ-Al₂O₃ catalyst. For the comparison purpose, the dehydrogenation of methylcyclohexane (MCH) was also studied. The experiments were performed in a fixed bed reactor and within a temperature range of 220 °C to 380 °C. The reactor pressure was maintained at 1.013 and 5 bar, and the H₂-to-HC molar ratio was set between 0 and 8.4. Under the conditions of experimentation, both the dehydrogenation and the hydrogenation reactions were found to take place with MCHe and MCHde. The presence of hydrogen in the feed was observed to facilitate the dehydrogenation reaction. For equimolar H₂/HC ratio, 320 °C reactor temperature, 1.013 bar, and W/F_HC0 equals to ~ 6.0 × 10⁴ s·g-cat/mol-HC, the yield of toluene obtained was 62.3, 82.9, and 99.6 mol/mol % for the reactants MCH, MCHe, and MCHde, respectively. Equilibrium constant expression for the dehydrogenation–hydrogenation reaction of MCHe was also worked out.

在室内1.0 wt％Pt / γ- Al ₂ O ₃催化剂上研究了1-甲基环己烯（MCHe）和1-甲基-1,4-环己二烯（MCHde）的脱氢反应。为了比较，还研究了甲基环己烷（MCH）的脱氢。实验在固定床反应器中，温度范围为220°C至380°C。反应器压力维持在1.013和5巴，并且H ₂ -HC的摩尔比设定在0和8.4之间。在实验条件下，发现MCHe和MCHde均发生了脱氢和氢化反应。观察到进料中氢的存在促进了脱氢反应。对于等摩尔H ₂/ HC比，320°C反应器温度，1.013 bar和W / F _{HC 0}等于〜6.0×10 ⁴  s·g-cat / mol-HC，得到的甲苯收率为62.3、82.9和99.6 mol /分别为反应物MCH，MCHe和MCHde的摩尔％。还计算了MCHe的脱氢-加氢反应的平衡常数表达。
