焦炭与co2和水蒸气气化后孔隙结构和高温抗压强度研究
, PP. 654-662
Keywords: 焦炭,溶损率,孔隙结构,高温,抗压强度
Abstract:
？通过焦炭气化反应装置和高温抗压强度测定装置,研究了焦炭与co2和水蒸气气化后孔隙结构变化规律及溶损率、温度和孔隙结构对焦炭高温抗压强度的影响。结果表明,与co2气化相比,水蒸气气化后焦炭平均孔径较小,比表面积和100μm以下气孔数量增加,且整体高温抗压强度更高。焦炭气化后高温抗压强度随溶损率增加而降低,随温度升高而降低。温度为1200℃时,随溶损率增加压缩过程焦炭承受压缩功(wocu)逐渐降低,水蒸气气化后的wocu高于co2条件,随溶损率增加焦炭压缩过程形变量呈降低趋势。在相同溶损率下,水蒸气气化后焦炭的孔隙结构对焦炭强度损害相对较小,抗变形能力更强。
