(544fm) A Comparative Study of Nickel Impregnated Zrtialox Catalysts for Hydrogen Gas Production Via Reforming of Methane
The catalytic performance tests for the steam and dry reforming of methane were conducted at 600â and atmospheric pressure with GHSV = 25,000 h-1 in a fixed bed reactor. The prepared catalysts before and after the reaction were studied by several characterization techniques such as N2 physisorption, XRD, CO2-TPD, DR-TPSR with MS, TGA, TPH and TPR. It was observed that the nickel based catalyst supported on the Ti modified ZrO2-Al2O3 showed higher catalytic stability rather than Ni/ZrO2-Al2O3 catalyst. These result can interpreted that the Ti supported on ZrO2-Al2O3 plays important role in the reduced the big ensemble, and suppress the coke formation at lower temperature.
