title = "Modeling of sorption enhanced steam methane reforming in an adiabatic packed bed reactor using various CO2 sorbents",
abstract = "A 1-D heterogeneous model of sorption-enhanced steam methane reforming (SE-SMR) process in a packed bed reactor consisting of nickel catalyst well mixed with CO 2 sorbent particles is investigated for three types of common sorbents. The performance of SE-SMR process is studied under low medium pressure conditions (3 – 11 bar) to find the optimum operating conditions. Optimal CaO sorption corresponding to 82% CH 4 conversion and 85% H 2 purity is found at 900 K, 3 bar, 3.5 kgm −2s −1 and S/C of 3.0. In contrast, lithium zirconate (LZC) and hydrotalcite (HTC) sorbents exhibited best sorptions under the operating conditions of 773 K, 5 bar and S/C of 3 with CH 4 conversion of 91.3% and 55.2%, and H 2 purity of 94.1% and 77.8% respectively. In these conditions, the CH 4 conversion increased by 114%, 111% and 67% compared to the conventional SMR for the processes enhanced by HTC, LZC and CaO sorption respectively. ",
