摘要：在常压下,1000～1500℃温度范围内,测定了大同等地的3种煤焦的孔构造和煤焦与二氧化碳的气化反应速率;研究了反应过程中,煤焦的孔结构和内表面积的变化及它们与气化速率间的关系。结果表明,高温下煤焦气化反应在细孔内表面上进行,细孔对气化反应速率起主要作用。
The pore structure of Datong, Newlands (NL), and Blair Athol (BA) coal chars, and the rate of gasification of these chars with CO2 were measured at 1000-1500℃ and under normal pressure. The relationship of the change of pore structure and inner surface area during gasification with gasification rate was studied. Char gasification was shown to be carried out on the inner surface area of microporosity at high temperature, so the microporosity plays an important role in gasification.
