The methane conversion rate and hydrogen yield in methane steam reforming(MSR)were calculated based on Chemkin's honeycomb monolithic reactor.This aims to obtain the effect of different operating parameters(the reactor temperature,the molar ratio of steam to carbon,i.e.,the ratio of water to carbon,and pressure)on the methane conversion rate and hydrogen yield.Different operating parameters were optimized by the response surface methodology and Box-Behnken-Design model,so to establish a response model with hydrogen yield as the response target.The results show that the ratio of steam to carbon and the reactor temperature have the most significant effect on hydrogen yield.When the temperature is 1079.65 K,the ratio of steam to carbon is 3.94,the pressure is 0.11 MPa,and the average hydrogen yield after simulated operation for three times is 80.58％.The method of combining the simulation of chemical reaction with numerical result prediction is adopted,thus significantly reducing the simulation time and improving the calculation efficiency and accuracy.
