在周期性双固定床反应器上，研究了CaO吸附剂与Ni重整催化剂的混合物对乙醇吸附强化重整反应的影响。根据热力学数据计算了SER工艺的最佳参数。实验在循环模式下进行，变温吸附和变压吸附（PSA）模式用于定期吸附剂再生。结果表明，吸附-催化乙醇重整反应的连续产氢量和氢气纯度保持在恒定水平，分别为50 L/min和97-99 vol. %分别双固定床SER反应器在2个月的运行和250多个循环期间工作良好。吸附剂和催化剂在实验过程中都保持了足够的活性。研究结果表明，吸附强化重整制氢技术是一种有前景的燃料电池热电联产制氢技术。
The sorption enhanced reforming (SER) of ethanol over an admixture of CaO sorbent and Ni reforming catalyst has been experimentally studied in a periodically operated dual fixed bed reactor. The optimal parameters for SER process were calculated from thermodynamic data. The experiment was carried out in cyclic mode; temperature swing adsorption and pressure swing adsorption (PSA) modes were used for periodic sorbent regeneration. It was shown that the continuous hydrogen production and the purity of hydrogen during the sorption-catalytic ethanol reforming maintained at the constant level and were 50 L/min and 97–99 vol.% respectively. The dual fixed bed SER reactor worked fine during 2 months on stream and more than 250 cycles. Both the sorbent and the catalyst maintained the sufficient activity during experiment. The obtained results suggest that sorption enhanced reforming may be a perspective approach for hydrogen production in fuel cell powered cogeneration systems.
