The catalyst slurry was composed of CuO/ZnO/Al2O3/V2O3 powder dispersed in 2-propanol and was sprayed on a curved stainless steel surface. The coating was found to exhibit good adhesion to the metal surface and to provide a considerable increase in surface area relative to the geometrical area of the metal support surface (up to a factor of 11000). The effects of key method parameters, namely, the size of the catalyst particles in the suspension and the coating thickness, on the efficiency of coating and the morphology and durability of the coating were briefly investigated. The intrinsic kinetics of carbon dioxide and carbon monoxide hydrogenation, as well as the WGS reaction, on the prepared plate catalyst were evaluated and compared to literature data. The reactions were carried out in a continuous stirred-tank reactor (CSTR) system appropriately assembled with a curved plate catalyst in the absence of mass-transfer limitations.
