Syngas production in DRM by use Ni,Pd,Pt/CaO catalyst with ZrO2 as promoter

Abstract

Through adopting the co-precipitation method using K2CO3Nickel, palladium and platinum catalysts (every 1 wt.%) On CaO and ZrO2 to develop Pt,Pd and Ni /Ca1-xZrxO (where x = 0, 0.03, 0, 07 and 0.15) were manufactured. As a precipitate, X-ray diffraction (XRD), X-ray photoelectric spectroscopy (XPS), Brunauer-Emmett-Teller (BET), Transmission Electron Microscope (TEM), Programmed H2 (H2-TPR) and thermo-thermal analysis (TGA). Pt,Pd,Ni/Ca0.85Zr0.15O reported best methane dry reform (DRM) activity at 98.02% and 85.94% for Carbon dioxide and methane conversions and 1.14 for H2/CO- ratio at 900°C and 1:1 of CH4:CO2 ratio. Various effects were observed when ZrO2 was used as a catalyst promoter. First, the cubic CaO stage has stabilized. Second, there was an increase thermal stability and basic support. In the end, carbon deposits and Ni2+, Pd2+ and Pt2+ ions have shrunk
