Novel reactor-membrane permeator methane-steam reforming process for enhanced recovery of H{sub 2} and CO{sub 2}
- ZiVaTech, Los Angeles, CA (United States)
A novel reactor-permselective membrane permeator process is described and mathematically modelled in terms of its inherent process variables. The process is suitable for methane-steam reforming and water gas-shift applications. It was developed to enhance the H{sub 2} and CO{sub 2} reaction product recovery and utilization by operating a membrane permeator between two methane-steam reforming reactors. Polyimide membranes in permeator highly selective to both H{sub 2} and CO{sub 2} versus CH{sub 4} and CO were tested in various simulation cases. It is shown that the reactor-permeator process can be indeed more effective (offers higher CH{sub 4} conversions and H{sub 2}, CO{sub 2} yields) than conventional equilibrium operated reactor-separator methane-steam reforming processes currently in practice. The study reveals that highly permeable and selective polyimides, such as the reportedly measured 6FDA-3,3{prime},5,5{prime}-TMB can be successfully applied to increase the process efficacy. 13 refs., 6 figs.
