Medium‐temperature shift (MTS) reaction was investigated in a microchannel reactor using the electrophoretic deposition (EPD) method to coat porous layers of Ni‐K/CeO₂ catalyst on stainless‐steel plates. The electrolyte suspensions of the catalyst were prepared in isopropanol, ethanol, methanol, and acetone as solvents. All EPD experiments were carried out under similar conditions (i.e., for a contact time of 3 min, at a voltage of 140 V, and in the presence of 0.3 wt % polyethylenimine as the dispersant). The effect of the different solvents on the coated catalytic layers was studied using Fourier transform infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, and 2D and 3D optical imaging. The experimental results proved that the best performance for the MTS reaction in the plate microreactor was achieved with isopropanol as the solvent.

微通道镍基催化涂层反应器中的水煤气变换反应：溶剂的影响

在微通道反应器中使用电泳沉积（EPD）方法研究中温转变（MTS）反应以涂覆Ni-K / CeO ₂多孔层不锈钢板上的催化剂。在异丙醇，乙醇，甲醇和丙酮作为溶剂中制备催化剂的电解质悬浮液。所有EPD实验均在相似的条件下进行（即，在140 V的电压下，在0.3 wt％的聚乙烯亚胺作为分散剂的情况下，接触时间为3 min）。使用傅立叶变换红外光谱，X射线衍射，扫描电子显微镜以及2D和3D光学成像研究了不同溶剂对涂层催化层的影响。实验结果证明，以异丙醇为溶剂，可实现平板微反应器中MTS反应的最佳性能。
