Abstract

Compact fuel processors based on steam reforming process using natural gas, liquefied petroleum gas (LPG) and biogas have been developed for over a decade in order to offer the fuel gas (hydrogen) into the combined heat and power (CHP) fuel cell systems for cogeneration of electricity and heat. Numerical modelling of a steam reforming reactor described by fully coupled mass, energy and flow equations was developed in this paper by using the Finite Element Method (FEM) based Comsol Multiphysics software version 5.2. Here, a steam reformer tube model formed by a catalytic bed, heating gas tubes and an insulating jacket was considered. In this paper, we propose to establish the influence of heating tube diameter and insulating jacket thickness on the heat transferred through catalytic bed and on the mass fractions of propane and hydrogen consumed and produced, respectively, during the endothermic reaction.
