K-CoMoS催化剂上合成气制低碳醇的宏观动力学OA北大核心CSTPCD
Apparent kinetics of syngas to higher alcohols catalyzed by K-CoMoS catalyst
针对K促进的掺杂Co的MoS2 催化剂(K-CoMoS),设计合成气(H2+CO)制低碳醇的动力学实验,利用固定床反应器测定反应数据,建立 CO 消耗和低碳醇生成的宏观动力学模型.模型参数回归结果表明,CO 消耗活化能为105.16 kJ·mol-1,低碳醇链增长活化能为 56.9 kJ·mol-1,链终止活化能为 55.2 kJ·mol-1,链增长的反应速率低于链终止的反应速率,是速率控制的关键步骤.通过动力学模型预测,提高CO分压有利于提高低…查看全部>>
A kinetic experiment was designed for the synthesis of higher alcohols from syngas using the K promoted MoS2 catalyst incorporated with Co(K-CoMoS),and the reaction results in a fixed bed reactor were obtained and the corresponding apparent kinetic models of CO consumption and higher alcohols formation were established.The regression results of model parameters show that the activation energy of CO consumption is 105.16 kJ·mol-1,and the energies of higher al…查看全部>>
