Hydrogen production from dry reforming of methane over LaNixCe1-xO3 (x=1, 0.75, 0.5, 0.25, 0) Perovskite type Catalysts

Abstract

Methane Dry Reforming is one of the encouraging methods for synthesis of syngas (mixture of CO & H2) and simultaneous utilization of Greenhouse gases like methane (CH4) and carbon dioxide (CO2). In this paper, a sequence of bulk catalysts of different ratios of Nickel/Cerium in Perovskite type catalyst LaNixCe1-xO3 (x=1, 0.75, 0.5, 0.25, 0) were prepared via sol-gel method and prepared catalysts were used in experimental observation of dry reforming to obtain conversion, selectivity and yield. The dry reforming reaction of methane (DRM) was investigated by using gas mixtures of CH4, CO2, and N2 (carrier gas) in the 1:1:2 ratio and with the total flow rate of 100ml/min. The reaction was performed at 800OC temperature and 1 atm pressure. Among different compositions of catalysts LaNixCe1-xO3, LaNi0.75Ce0.25O3 catalyst that gives conversion of CO2 and CH4 production as highest as 94.84% and 86.15% respectively was found be most active. Also yield of H2 and CO production were highest at 64.56% and 88.78% respectively for LaNi0.75Ce0.25O3.
