A novel membrane reactor concept for CO2-hydrogenation to methanol application was proposed, and simulation results showed that the fine distribution of CO2 can improve the selectivity of methanol production by 6% within the studied operating conditions.
We present a novel membrane reactor (MR) concept for CO2-hydrogenation to methanol application, in which CO2 is supplied from a CO2 -rich gas stream via a membrane and is distributed along the catalytic packed bed, where it reacts with hydrogen over a CuO - ZnO/Al2O3 catalyst to produce methanol. The performance of the reactor was investigated using a set of two-fluid model simulations. The simulation results showed that the fine distribution of CO2 improved the selectivity of methanol production by a value of 6 % for the studied range of the operating conditions.
