Abstract

Gasification of coke and mixture of coke and anthracite with CO_2,and the coke microstructure before and after gasification were analyzed in order to study the behavior of anthracite in coke gasification.The results show that anthracite has a function to protect coke in gasification,and due to the priority of anthracite in gasification and caused change in CO_2 concentration.The isotropic structure of coke is protected prominently from gasification by anthracite,and the protection is less for the coke with strong anisotropic structure.
