A two-dimensional transient model has been developed to describe the catalytic methane reforming (MSR) coupled with simultaneous CO 2 removal by different absorbents under non-isothermal, non-isobaric and non-adiabatic operating conditions. The influences of temperature, pressure and steam/carbon (S/C) on enhancement were taken into account. The results showed that the hydrogen mole fraction (dry basis) higher than 94% could be achieved using Li 4 SiO 4 , CaO, and HTC as CO 2 acceptors at the operating conditions of 550°C and 0.1 MPa. When the reaction temperature varied from 500°C to 600°C, the initial CO 2 capture rates were HTC>CaO>Li 4 SiO 4 >Li 2 ZrO 3 , and the saturation rates HTC>CaO>Li 4 SiO 4 >Li 2 ZrO 3 . Increasing the reaction temperature would improve the CO 2 capture rate and available CO 2 capacity. For Li 4 SiO 4 , although the adsorbing rate increased as the operating temperature increased, the capacity almost did not change. At 550°C, increasing the working pressure could promote the enhancing factors of Li 4 SiO 4 ,Li 2 ZrO 3 and HTC. There was an optimal steam/carbon ratio between 2-4.5 such that all CaO, Li 4 SiO 4 , HTC and Li 2 ZrO 3 would obtain the biggest enhancement for H 2 production at the pre-breakthrough stage.hydrogen production, steam reforming, sorption-enhanced reaction, CO 2 adsorbent Citation:Chen Y M, Zhao Y C, Zhang J Y, et al.
