The utilization of glycerol, primary byproduct of biodiesel production, is important to enhance process economics. In our recent prior work, it was shown that glycerol can be converted to hydrocarbon fuels over bifunctional catalysts, containing a noble metal supported on H-ZSM-5. Over Pd/H-ZSM-5 catalyst, an optimal ∼60% yield of hydrocarbon fuels was obtained. In the present work, based on experimental data over Pd/H-ZSM-5 catalyst, a lumped reaction network and kinetic model are developed. Using differential kinetic experiments over the temperature range 300–450°C, the rate constants, reaction orders, and activation energies are obtained for each reaction step. The predicted values match well with experimental data for glycerol conversion up to ∼90%. © 2017 American Institute of Chemical Engineers AIChE J, 2017

在Pd / H-ZSM-5催化剂上甘油转化为烃类燃料的动力学

甘油（生物柴油生产的主要副产品）的利用对于提高工艺经济性很重要。在我们最近的先前工作中，研究表明，甘油可以通过双官能催化剂转化为烃类燃料，该双官能催化剂含有负载在H-ZSM-5上的贵金属。在Pd / H-ZSM-5催化剂上，获得了约60％的最佳碳氢燃料收率。在目前的工作中，基于在Pd / H-ZSM-5催化剂上的实验数据，建立了集总反应网络和动力学模型。在300–450°C的温度范围内使用微分动力学实验，可以获得每个反应步骤的速率常数，反应阶数和活化能。预测值与甘油转化率高达90％的实验数据非常吻合。©2017美国化学工程师学会AIChE J，2017
