Effect of SiO2 on loss of catalysis of inherent metallic species in CO2 gasification of coke from lignite
Inherent metallic species retained by coal char or coke, such as Na and Ca, behave as catalysts in gasification. The char/coke normally contains inherent SiO2, which can react with the inherent catalysts to form silicates, resulting in catalyst deactivation over the range of pyrolysis, carbonization...
