Abstract
Reforming systems are thermodynamically limited by equilibria and require high temperatures to achieve a high yield. Membrane reactors can separate H2 into pure streams using a H2 selective membrane, thereby shifting the equilibria towards the product side. During this study the performance of a bi-reforming system model with and without a membrane was studied using Aspen Plus V1 and Aspen Plus Simulation Workbook Excel 2016. The performance was characterised with the H2 and CO yield, the CH4 and CO2 conversion, and the reactor duty. The modelling was done using Gibbs energy reactors. The influence of operating conditions of the temperature, pressure, CH4/CO2 ratio, and the steam to carbon ratio were studied. The simulations showed that the base system without a membrane achieved a higher performance, as the membrane has a maximum operating temperature of 600°C, while the base system was not limited by the temperature. Therefore, the base system could be run at much higher temperatures.
