چکیده انگلیسی
Equilibrium shifting is considered to be effective for promoting H2 production by methane (CH4) steam reforming. In this study, a packed bed reactor with a mixture of reforming catalyst and CO2 absorbent was used. Pellets of lithium silicate (Li4SiO4), which Toshiba has developed, were applied as the absorbent. This is a report on the relationship between CO2 absorption by Li4SiO4 pellets and the equilibrium-shift effect for overall reactions. Experiments showed that there was a strong influence of temperature on the equilibrium-shift effect. The effect was obvious, which resulted in keeping not only the concentration of H2 above 93 vol% but also that of CO below 0.2 vol% at 550 °C.
