摘要
本研究的目的是通过将催化剂浸泡在改性聚合物前驱体溶液中,使其在金属表面原位生长,从而在铁铬铝单片上沉积镍-拉-锆催化剂。通过 X 射线衍射、原子力显微镜和扫描电子显微镜对制备的整体石进行了表征,并在模拟沼气(CH4/CO2 = 3)的三重转化反应中进行了合成气生产测试。在 50 小时的测试中,整体催化剂比粉末催化剂具有更好的稳定性。相比之下,粉末状催化剂的失活更为明显,这与较高的碳沉积有关。这项研究提供了一种在铁铬铝整体石上沉积镍基催化剂的简单方法,用于沼气三重转化反应,为沼气提纯提供了有价值的信息。
Facile deposition of a Ni–La–Zr catalyst on a FeCrAl monolith using the polymerized complex method: application to syngas production by tri-reforming of biogas
The aim of this study was to deposit a Ni–La–Zr catalyst on a FeCrAl monolith by in situ growth of the catalyst on a metallic surface through immersion in a modified polymeric precursor solution. The prepared monolith was characterized by X-ray diffraction, atomic force microscopy, and scanning electron microscopy and was tested in a tri-reforming reaction of simulated biogas (CH4/CO2 = 3) for synthesis gas production. The monolithic catalyst presented better stability than the powdered catalyst under the 50-h test. In contrast, the powdered catalyst showed more pronounced deactivation, which was associated with higher carbon deposition. This study provides valuable information on a simple deposition method for Ni-based catalysts on FeCrAl monoliths for biogas tri-reforming reactions, which could have implications for biogas upgrading.
