The present studies have been investigated to suppress the carbon deposition by various promoters (Mg, Zr, Ce, Fe) over Ni-based catalysts in steam-CO2 reforming of methane(CSCRM) to produce synthesis gas(H2/CO = 2) for gas to liquid(GTL). The study investigates the optimal promoter content (3wt%, 5wt%, 7wt%) by co-impregnation method and sequential-impregnation method respectively. The catalytic reactions were tested at 900°C and 20 bar in the composition CH4:CO2:H2O:Ar = 1:0.7:15:1 and GHSV = 25200 h-1. XRD, BET, TGA and SEM have been used for catalyst characterization. Further study on long-term catalyst stability should be mad |
