Catalytic NO–H2–CO–O2 reaction was studied over Pt-supported Ln-incorporated FSM-16 (Ln = La, Ce and Pr). Pr-FSM-16 exhibited the highest activity for NOx reduction at ≤200 °C. Pr has an effect of increasing the basicity to promote the oxidative adsorption of NO, which is a key for efficient de-NOx.
The results of research of the Pt-, Ru- and Pt–Ru/2% Ce/(θ + α)-Al2O3 catalysts with various ratio of Pt to Ru for selective catalytic oxidations of CH4 into synthesis-gas at short contact times are presented. Optimum conditions for preparation of catalysts were found. It was established that the CH4 conversion at 1,173 K changes from 96 to 100%, selectivity by H2—100%, and CO—95–100% at contact times...
