Abstract
CO2 methanation by using distributor type membrane reactor was investigated to control the reaction rate by distributed reactant feeding through membrane. Accurate evaluation of the thermal conductivity of the porous Al2O3 membrane, considering its fine physical and chemical structures, was achieved by measurements using Laser Flash Analysis. In the solid part of the 1TC sample, the thermal conductivity was found to be 36.4 % lower than that of non-porous alumina. A catalytic membrane with a silica separation layer, having an H₂ permeance of 1.4 × 10⁻⁶ mol m−2 s−1 Pa−1 and an H₂/CO₂ selectivity of 35.9, was used in the distributor type membrane reactor test, and a CO2 conversion of 92.3 % was obtained at 350 ℃. Based on these results, simulation was performed using Ansys Fluent to investigate the influence of membrane thermal conductivity and permselectivity. The CO2 permeance of the membrane was set equal to 3.91 × 10−8 mol m−2 s−1 Pa−1 for all conditions. It was shown that the CO2 permselective membrane (H2/CO2 selectivity = 35.9) produced about 1.4 times CH4 than the H2 permselective membrane (H2/CO2 selectivity = 0.10), and that higher thermal conductivity of the membrane suppressed the temperature rise in the reactor.
