Numerical Simulation and Calculation of Carbon Catalytic CH4-CO2 Reforming Reactor

CH 4 -CO 2 reforming to synthesis gas (syngas) (H 2 + CO), as well as the production of methanol, F-T synthesis, ammonia and other chemical products, has been extensively investigated.Conventional catalytic reforming methods use Ni-or noblemetal-based catalysts 1,2 .Noble metal-based catalysts have high activity and selectivity, but they are expensive.Nickel-based catalysts have higher activity and selectivity, but are easily deactivated by carbon deposition.Therefore, the development of new, low-cost catalysts resistant to carbon deposition is imperative.Our group has previously proposed the doublegas multi-generation technology (973 items) of a pyrocarbon system under coke oven gas and gasification gas.Using coke oven gas (27 % CH 4 ) and gasification gas (20 % CO 2 ), CH 4 -CO 2 is reformed to syngas at a high temperature with carbon catalyst further integrating the synthetic alcohol-ether fuels 3 .Based on this small-scale experimental study 4 , a pilot carbon catalytic CH 4 -CO 2 reforming reactor was developed and a numerical simulation was carried out in the current work.A simulation study for coke oven gas and mixed-intake gasification gas was performed.Partial oxidation of oxygen was achieved with a carbon catalyst for temperature field, flow field and component distribution in the reforming reactor to verify the performance of the designed pilot-reforming reactor.Based on simulation result predictions, an actual carbon catalytic CH 4 -CO 2 reforming reactor was developed.
