Kinetics analyses of methanol synthesis with cornstalk syngas

摘要

The reaction kinetics of methanol synthesis for the cornstalk syngas has been studied in a tubular-flow integral and isothermal reactor. A domestic Cu-based catalyst C301 (Particle size: 0.175 mm×0.147 mm) was used. The temperature varied from 210°C to 270°C. The pressure was 5 MPa intrinsic kinetic model was used. The improved Gauss-Newton method was used to confirm the parameters of the kinetic model. The statistic test and residual error distribution proved that the Langmuir-Hinshelwood type intrinsic kinetic model could be well employed to simulate the reaction kinetics, which can be further used to design the methanol synthesis reactor and the industrial test of methanol production from biomass (cornstalk) gas.
