Abstract
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 °C. 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.
