In this work several CuO–ZnO/Al₂O₃ co-impregnated catalysts were tested for methanol steam reforming (MSR) in order to statistically optimize the Cu and Zn content. All catalysts showed initial deactivation, due to Cu sintering, which was detected by the BET area and transmission and scanning electronic microscopy analyses, performed before and after the reactions. The products obtained in the reactions were only H₂ and CO₂, and the formation of CO or coke was not verified. It was possible to adjust a second order equation to the methanol conversion (after 3 h in reaction) as a function of the Cu and Zn content, using the RStudio free program. The optimum composition obtained by the surface response methodology (RSM) was 20.7% Cu and 13.4% Zn, and the catalyst synthesized with this content (19.4% Cu–15.5% Zn) had the highest Cu area and dispersion and thus presented the highest methanol conversion, corroborating the statistical analysis.

在这项工作中，对几种 CuO-ZnO/Al ₂ O ₃共浸渍催化剂进行了甲醇蒸汽重整 (MSR) 测试，以在统计上优化 Cu 和 Zn 含量。由于铜烧结，所有催化剂都显示出初始失活，这通过反应前后进行的 BET 区域和透射和扫描电子显微镜分析检测到。反应得到的产物只有H ₂和CO ₂，并且未验证 CO 或焦炭的形成。可以使用 RStudio 免费程序将二阶方程调整为甲醇转化率（反应 3 小时后）作为 Cu 和 Zn 含量的函数。通过表面响应法 (RSM) 获得的最佳组成为 20.7% Cu 和 13.4% Zn，以该含量 (19.4% Cu–15.5% Zn) 合成的催化剂具有最高的 Cu 面积和分散度，因此呈现出最高的甲醇转换，证实了统计分析。
