Contribution of Oxide Supports in Nickel-Based Catalytic Elimination of Greenhouse Gases and Generation of Syngas

Carbon dioxide and/or dry methane reforming serves as an effective pathway to mitigate these greenhouse gases. This work evaluates different oxide supports including alumina, Y-zeolite and H-ZSM-5 zeolite for the catalysis of with Nickel (Ni). The composite catalysts were prepared by impregnating Ni (5%) followed calcination. supported exhibited more reducibility basicity compared alumina catalysts, this was assessed temperature programmed reduction using hydrogen desorption carbon dioxide. catalytic activity, in terms CH4 conversion, indicated that 5 wt% on higher conversion (80.5%) than when (71.8%) or (78.5%). In contrast, catalyst led CO2 (87.3%) (68.4%) (83.9%) catalysts. stability tests 9 h time-on-stream showed had less deactivation (just 2%) due deposition. characterization spent oxidation (O2-TPO), X-ray diffraction (XRD) thermo-gravimetric analysis (TGA) revealed deposition a main cause it occurred lowest degree catalyst.
