Membrane Reactor for Methanol Synthesis Using Si-Rich LTA Zeolite Membrane
We successfully demonstrated the effect of a membrane reactor for methanol synthesis to improve one-pass CO(2) conversion. An Si-rich LTA membrane for dehydration from a methanol synthesis reaction field was synthesized by the seed-assisted hydrothermal synthesis method. The H(2)O permselective perf...

description | We successfully demonstrated the effect of a membrane reactor for methanol synthesis to improve one-pass CO(2) conversion. An Si-rich LTA membrane for dehydration from a methanol synthesis reaction field was synthesized by the seed-assisted hydrothermal synthesis method. The H(2)O permselective performance of the membrane showed 1.5 × 10(−6) mol m(−2) s(−1) Pa(−1) as H(2)O permeance and around 2000 as selectivity of H(2)O/MeOH at 473 K. From the results of membrane reactor tests, the CO(2) conversion of the membrane reactor was higher than that of the conventional packed-bed reactor under the all of experimental conditions. Especially, at 4 MPa of reaction pressure, the conversion using the membrane reactor was around 60%. In the case of using a packed-bed reactor, the conversion was 20% under the same conditions. In addition, the calculated and experimental conversion were in good agreement in both the case of the membrane reactor and packed-bed reactor. |
