Validation of Consecutive Coke and SiC Formation on Ni Core-Shell Microspheres During Methane Decomposition

Abstract

Nickel based MCM-41(Ni/MCM-41) and silica microsphere (Ni/SiO2) were synthesized and tested against consecutive coke deposition and SiC formation in a model methane decomposition reaction. Results indicated coke deposition on both (Ni/MCM-41 and Ni/SiO2) catalysts and exclusive SiC formation due to utilization of coke deposited on Ni/SiO2 catalyst. [GRAPHICS] .
