عنوان مقاله [English]
The performance of M/ZnLaAlO4 and M/γ–Al2O3 catalysts (M=Cu,Cu–Ni) in methanol reforming process in the temperature range of 200-350 oC, methanol feed GHSV of 11500 h-1, and atmospheric pressure in a fixed bed quartz reactor has been investigated in this work. Surface area, morphology, and crystal structure of the synthetic catalysts were studied using BET, FESEM, FIR, XRD, and TPR analyses for better assessment of the catalysts. The results have shown that the spinel based M/ZnLaAlO4 catalyst possesses high yield, very high catalytic activity, low reduction temperature, and large pore sizes, giving a higher percentage of loading and better distribution of the active metal. The new support catalyst selectivity is less carbon monoxide. Finally, the bimetallic catalyst, nickel leads to better dispersion of copper particles and increases the activity but also high selectivity to the carbon monoxide.
