Abstract
The possibility of applying a catalytic membrane reactor (CMR) to SO3 decomposition in a low–temperature range with the purpose of producing CO2–free hydrogen in Iodine–Sulfur thermochemical cycle was reviewed. A membrane reactor simulation, which is a one-dimensional, isothermal and plug–flow model, was introduced to clarify the strategy for the fabrication of membranes (O2 permeance, selectivity (O2/SO2, O2/SO3)) for the H2SO4 decomposition in IS thermochemical processes. The O2/SO2 permeation properties through organosilica membranes were introduced.
