Abstract Dry reforming of propane (DRP) with CO2 was examined over iron–ceria spinel (FeCe2O4) that was synthesized on mesoporous alumina foam by the sol–gel method. The FeCe2O4/Al-F catalyst exhibited significant catalytic activity for the DRP with propane and CO2 conversions of 93% and 76%, respectively. Moreover, the redox behavior of the spinel was found to greatly reduce the deposition of carbon, which could be attributed to the oxidation of surface carbon to CO via the interaction with FeCe2O4 lattice oxygen. The FeCe2O4/Al-F catalyst with good catalytic activity, long-term stability and coke resistance may be a promising candidate for the DRP.

铁-氧化铈尖晶石 (FeCe 2 O 4 ) 催化剂，用于丙烷干重整以抑制碳形成

摘要 通过溶胶-凝胶法在介孔氧化铝泡沫上合成的铁-氧化铈尖晶石 (FeCe2O4) 上研究了用 CO2 干法重整丙烷 (DRP)。FeCe2O4/Al-F 催化剂对 DRP 表现出显着的催化活性，丙烷和 CO2 的转化率分别为 93% 和 76%。此外，发现尖晶石的氧化还原行为大大减少了碳的沉积，这可能是由于表面碳通过与 FeCe2O4 晶格氧的相互作用氧化为 CO。具有良好催化活性、长期稳定性和抗焦性的 FeCe2O4/Al-F 催化剂可能是 DRP 的一个有希望的候选者。
