Kinetics of glycerol conversion to hydrocarbon fuels over Pd/H-ZSM-5 catalyst

What is it about?

The utilization of glycerol, primary byproduct of biodiesel production, is important to enhance process economics. Inour 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 hydrocarbonfuels was obtained. In the present work, based on experimental data over Pd/H-ZSM-5 catalyst, a lumped reaction net-work and kinetic model are developed. Using differential kinetic experiments over the temperature range 300–4508C,the rate constants, reaction orders, and activation energies are obtained for each reaction step. The predicted valuesmatch well with experimental data for glycerol conversion up to 90%
