摘要:
采用Benson基团贡献法计算了苯、甲苯和乙苯的标准摩尔生成焓和绝对熵;并计算了不同反应温度和压力条件下,环己烷、甲基环己烷和乙基环己烷脱氢反应的标准摩尔反应焓变、标准摩尔吉布斯自由能变和平衡常数。结果表明:环己烷、甲基环己烷和乙基环己烷脱氢反应均为吸热反应;3个脱氢反应的标准摩尔反应焓变、标准摩尔吉布斯自由能变和平衡常数,随反应压力和温度变化趋势相近;在300~1 000 K和0.5~30.0 MPa的条件下,升高反应温度有利于脱氢反应进行,升高反应压力不利于脱氢反应进行。
Abstract:
Standard molar enthalpy of formation and standard molar entropy of benzene, toluene and ethylbenzene were calculated by Benson group contribution method. The changes in enthalpy, Gibbs free energy and equilibrium constants of the dehydrogenation of cyclohexane, methyl cyclohexane and ethyl cyclohexane at different temperatures and pressures were calculated. The results showed that the dehydrogenation of cyclohexane, methyl cyclohexane and ethyl cyclohexane were all endothermic reactions, and the dehydrogenation reactions had similar trends with pressure and temperature. In the range of 300-1 000 K and 0.5-30.0 MPa, the increase of reaction temperature was beneficial to the dehydrogenation, but the increase of reaction pressure was not beneficial to the dehydrogenation.
