摘要:采用固定床反应器,以水蒸气为气化介质,研究了金山石油焦和3种不同煤阶原煤(小龙潭褐煤、神府烟煤、高平无烟煤)的共气化反应特性,考察了不同煤阶原煤对煤-石油焦共气化反应活性和产物气组成的影响,以及含碳物料的气化反应活性与其CO2吸附量的关系.结果表明,向石油焦中添加一定量的原煤,可在一定程度上改善石油焦的气化反应活性,提高气体产物中H2含量,如小龙潭褐煤的添加量为40%时,其与石油焦共气化反应活性约为石油焦单独气化时的2~3倍,气体产物中H2含量提高了12%;煤与石油焦共气化的反应活性、气体产物中H2以及合成气(H2 +CO)含量均按小龙潭褐煤、神府烟煤、高平无烟煤的顺序依次降低;由于3种原煤中活性金属组分含量的不同,其对应的CO2吸附量表现出一定差异.此外,含碳物料的气化反应速率与CO2强吸附量呈线性关系,拟合强度范围为0.97~0.99,CO2吸附量可作为表征含碳物料气化反应活性大小的一项指标.
Steam co-gasifications of Jinshan petroleum coke (JSPC) with three kinds of coal, Xiaolongtan (XLT), Shenfu (SF), Gaoping (GP), were investigated in a laboratory fixed-bed reactor to examine the effects of coal kind on co-gasification activity, gas yield and gas composition. In addition, CO2 chemisorption characteristics of these materials were analyzed to investigate the relationship between chemisorption and gasification reactivity. The results indicated that at the same gasification temperature, with the increase of the content of coal in coal-petroleum coke co-gasification, not only the reactivity was improved remarkably, but also the release rate of H2 increased greatly. When the content of XLT was 40%, the reactivity of XLT-JSPC co-gasification was about 2--3 times more than that of petroleum coke alone and the yield of H2 raised nearly 12 percentage points. According to the reactivity, the contents of H2 and available gas (H2-+-CO) in gas product of co-gasification from high to low, the three coal-petroleum coke co-gasification systems were in the order of XLT-JSPC, SF-JSPC and GP-JSPC. As the different content of active mental in the three coals, their CO2 chemisorption masses were different. Besides, the gasification reactivity rate increased linearly with the increase of CO2 strong absorption mass (Cs,r), the fitting strength was in the range of 0. 97--0. 99, which means that CO2chemisorption mass can be an indexof the gasification activity of carbonaceous materials.
