An experimental program on membrane assisted WGSR and a membrane reactor (MR) modeling aimed at finding a sensitivity envelope of the key parameters controlling MR performance was carried out using bitumen and coke-coal gasification streams at 450 ¡ãC. It was determined that a Langmuir-Hinshelwood (LH) model of the kinetics fit adequately the conventional reactor (CR) experimental data. To simulate the MR performance the LH kinetic parameters were applied to MR data that showed a 7 % enhancement of CO conversion over the CR. The model predicted that by adjusting the MR operating parameters within reasonable limits, the CO conversions in the range of 98 % could be reached, at least 15 % over the thermodynamic equilibrium conversion of a conventional system.
