  • Abstract It is a long-term research objective for this laboratory to design a membrane reactor for methanol steam reforming that produces pure hydrogen in a compact size without external heat source. The objective of this study, which is a beginning step of the long-term project, is to develop a mathematical model for a single-jacked membrane reactor for methanol steam reforming with kinetic data of catalyst and permeability of Pd membrane obtained experimentally in this laboratory.
    The kinetic data over Pt-promoted CuO/ZnO/Cr2O3/CeO2/Al2O3 catalyst obtained in this laboratory were regressed to two models of rate equations. The average errors for model predictions of conversions are 0.06349 for Model 1 which has six parameters and 0.05036 for Model 2 which has eight parameters.
       A mathematical model for a single-jacked membrane reactor has been developed. Sievert’s law is used for hydrogen permeation and modified Soave-Redlish-Kwang equation of state is adopted to calculate the fugacity coefficients for methanol and water to account for the non-ideality at high pressure. A Fortran program has been established for the simulation of the single-jacked membrane reactor with all the parameters measured in the experiment. The simulation results can help us to understand the effects of design variables, such as load to surface ratio, WHSV, catalyst weight and permeability, on the hydrogen production yield or hydrogen flux.
