摘要
为了考察煤炭地下气化工业试验基地废水的催化活性,探究利用该废水进行地下催化气化工业性试验的可行性,对乌兰察布褐煤进行了不同压力下的活性评价实验.结果表明,煤炭地下气化废水对乌兰察布褐煤的气化起到了良好的催化效果,在添加一定量煤炭地下气化废水后,其碳转化率由80.19%提高到89.82%;煤气产率由4.2m3/kg增加到5.2m3/kg,增加了原来的23.8%.随着反应压力的提升,碳转化率及煤气产率均呈现不同程度的降低,煤气组分中H2,CO和CO2含量也呈现不同程度的降低;而CH4含量随着压力的提升持续增加.
In order to explore the catalytic activity of UCG waste water and test the feasibility of the underground coal gasification based on waste water, the catalytic gasification of Ulanqab lignite were carried out under different gasification pressure. The results show that the underground coal gasification waste water has beneficial catalytic effect. The carbon conversion increase from 80. 19% to 89. 82%. The gas yield increases from 4. 2 m^3/kg to 5. 2 m^3/kg, increased 23.8%. Following with the elevation of the reaction pressure, the carbon conversion and gas yield were reduced in different degree, the content of H2, CO and COz reduced also; but the content of CH4 continued to increase.
