Coal influenced to microstructure during reaction of coke gasification

With coke and the mixtures of coal and coke in the fixed bed gasifier for gasification reaction with CO_(2) and with HY-4 automatic micro photometer to measure the pore structure and optical textures of the coke, the paper discussed the influence of anthracite coal to the microstructure during the gasification reaction of coke. The results showed that with the anthracite coal added, the pore structure of the coke would be protected during the gasification. Under the high temperature, long gasification period and high reaction, the protection results would be obvious. The anthracite coal would be obviously to have the protection function of the isotropy structure for the coke. The more large of the anisotropy element is and the smaller of the protection function is.
