The sorption characteristics of the single-component gas(CH4,N2,CO2) and the binary gas with different proportion(80% CH4+20% CO2,50% CH4+50% CO2,20% CH4+80% CO2,80% CH4+20% N2,50% CH4+50% N2,20% CH4+80% N2) on long-flame coal,coking coal and anthracite were studied by means of isotherm adsorption experiment in laboratory.
通过长焰煤、焦煤和无烟煤对CH4,N2,CO2单组分和6种不同配比浓度(80%CH4+20%CO2,50%CH4+50%CO2,20%CH4+80%CO2,80%CH4+20%N2,50%CH4+50%N2和20%CH4+80%N2)二元混合气的等温吸附实验研究,探讨了3种不同煤级煤对单组分气体和不同配比二元混合气体的吸附特征。
Through the production practice of first grade metallurgical coke applicating the compensation of weak coking coal and long flame coal on stamt-charging coke oven,They are made proposals for saving coking coal and low sulphur fat coal and applicating coal source reasonably.
通过利用弱黏结性瘦煤、长焰煤的互补性在捣固焦炉上生产一级冶金焦的实践,节约了焦煤及低硫肥煤,从而为合理利用煤源提供了一个优化配煤方案。
It has been studied that adaptability of pressured gasification of long flame coal in the pressurized fixed bed gasifier (ID 100mm) Due to the has strong caking a stirrer was installed when it carried pressured gasification.
研究了一种长焰煤的固定床加压气化适应性。
In the middle Jurassic period coal seam, non-caking coal and long flame coal are most in reserves.
西北地区中侏罗纪的煤层多为不粘煤、长焰煤 ,其中不粘煤的煤岩显微组分以惰质组中的丝炭化物质居多 ,也见有镜煤透镜体 ,按镜质体反射率可将其变质程度分为Ⅰ、Ⅱ阶段 ,它与惰质组含量有很大关系 ,惰质组含量高 ,煤化程度低是造成煤对二氧化碳分解率高的主要因素之
