Abstract

Recently, ceramic-carbonate membrane reactors have been proposed to selectively separate CO2 at elevated temperatures and to valorize this pollutant gas by coupling a catalyzed reaction. This work explores using a membrane reactor to perform the oxidative reforming of propane by taking advantage of the CO2- and O2-permeating properties of a LiAlO2/Ag-carbonate membrane. The fabricated membrane showed excellent permeation properties, such as CO2/N2 and O2/N2 selectivity, when operating in the 725-850 °C temperature range. The membrane exhibited remarkable stability during the long-term permeation test under operating conditions, exhibiting minor microstructural and permeation changes. Then, by packing a Ni/CeO2 catalyst, the membrane reactor arrangement showed efficient syngas production, especially at temperatures above 800 °C. A hydrogen-rich syngas mixture was obtained by the contributions of the oxidative reforming and cracking reactions. Specific issues observed regarding the membrane reactor's performance are attributed to the catalyst that was used, which experienced significant poisoning by carbon deposition during the reaction, affecting syngas production during the long-term test. Thermodynamic calculations were performed to support the experimental results.

使用二氧化碳和氧气渗透膜对丙烷进行氧化转化生产合成气。
最近,有人提出利用碳酸陶瓷膜反应器在高温下选择性分离二氧化碳,并通过耦合催化反应使这种污染气体价值化。本研究利用 LiAlO2/Ag-carbonate 膜的二氧化碳和氧气渗透特性,探索使用膜反应器对丙烷进行氧化重整。所制造的膜在 725-850 ℃ 的温度范围内运行时显示出优异的渗透特性,如 CO2/N2 和 O2/N2 选择性。在运行条件下进行的长期渗透测试中,该膜表现出卓越的稳定性,微观结构和渗透性变化轻微。然后,通过填装 Ni/CeO2 催化剂,膜反应器装置显示出高效的合成气生产,尤其是在温度高于 800 ℃ 时。通过氧化重整和裂解反应的作用,获得了富氢合成气混合物。在膜反应器性能方面观察到的具体问题可归因于所使用的催化剂,该催化剂在反应过程中因碳沉积而严重中毒,影响了长期试验期间的合成气生产。为支持实验结果,进行了热力学计算。
