Research on function mechanism of coal in coke gasification reaction processing;

The kinetics of gasification reaction of coal char,with CO_2 serving as the gasifying agent,has been studied in a fixed bed test rig and the effect of alkali metal content,as well as that of temperature,on the reaction investigated.

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.

Several thermoanalytical methods such as the Freeman-Carroll differentiation method and the Coats-Redfern integration method were adopted to calculate the kinetic parameters of two kinds of anthracite gasification with CO_2.

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 main cause of coke broken in BF is the consumption of chemical reaction,Temperature,oxygen potential,reactivity of coke and alkali metal have important influences on coke gasification.

According to the relation formula between reactivity of coke and rate of gaseous reaction,the main factors influencing the high temperature properties of coke are as follows:alkalis,temperature,pressure,ash,microscopic composition and the reaction of H2O on coke,in this paper the influence of above factors on high temperature properties of coke have been analyzed.
