| Abstract: |
| The performance of Cu-Ni/LaZnAlO4 and Cu-Ni/-Al2O3 catalysts in methanol reforming process in a Monolith reactor in the temperature range of 200-350°C, feed flow rate of WHSV=20.8h-1 and atmospheric pressure has been investigated. In order to perform a more thorough investigation, surface area, morphology and crystalline structure of the synthetic catalysts have been studied using TPR and XRD analyses. The results have shown that Cu-Ni/LaZnAlO4 catalyst synthesized by combustion reaction method under ultrasound irradiation has a very high efficiency and catalytic activity, low reduction temperature, high mechanical resistance and large pore sizes. The latter, causing a higher percentage of active metal impregnation and better distribution on the support, greater resistance against sintering and maintaining catalyst inertness at temperatures of over 1000oC, in comparison with conventional catalysts such as Cu-Ni/-Al2O3, which make its substitution for currently used catalysts affordable. |
