Four methods were adopted to prepare samples 20%NiO/Al2O3 with calcination fixed at 500 °C, which were then reduced into 20%Ni/Al2O3 and used as catalysts for reaction of selective methanation of CO in H2-rich gas (CO-SMET). XRD and TPR measurements indicate that nickel aluminates were formed in the calcined samples and their formation was influenced by preparation methods. Higher temperatures were...
In order to find out the influence factors of SO2 removal efficiency with activated carbons, five kinds of powder activated carbons which have different physicochemical characteristics were choosed. As desulfurizer, every kind of them was used to remove SO2 from flue gas in a fluidized bed reactor. Their physicochemical characteristics were determined by N2 adsorption isotherm at 77 K, elemental analysis...
