Abstract：The alkali metal has a positive catalytic effect on coke gasification reaction. And coke gasification characteristics affect the energy utilization of blast furnace. The effect of CaO, which was added to coal before carbonization under laboratory conditions, on the strength, gasification temperature, average reaction rate of coke and its activation energy was researched. According to the quantificational research results shown when add 4% CaO component into coke, which strength decrease as much as 7%, gasification temperature decrease 80℃ at most, average gasification rate increase maximum and activation energy 30% smallest than that of coke with no addition.
