01.03.20121. Introduction. Dense-phase pneumatic conveying using various gasses has been applied in entrained-flow gasification of pulverized coal. When CO 2 was employed as carrier gas, it could react with coke to form CO. In comparison to N 2 as carrier gas, the concentration of (CO + H 2) in gaseous products increased and the percentage of N 2 showed a significant
