摘要
为研究不同热解条件下5种液氧致裂吸附材料的热解规律和热反应机理,提高液氧致裂过程中能量利用率和致裂效果。通过热重-红外联用分析仪(TG-FTIR)分析氧气和氮气氛围条件下5种液氧致裂吸附材料的热分析结果和气体析出特性,再单独对比分析较优液氧致裂吸附材料在不同氧气浓度中的热解过程。研究结果表明:氧气气氛下液氧致裂吸附剂热解效果更好,并且不同气流速对于液氧致裂吸附剂热解有一定的影响;以失重比为材料优选的衡量指标,其优选顺序为碳粉、碳棒、海绵、泡沫碳、木质纤维;研究成果为液氧致裂技术提供一定的技术参考。
In order to study the pyrolysis pattern and thermal reaction mechanism of five liquid oxygen fracturing adsorbent materials under different pyrolysis conditions,and to improve the energy utilisation and fracturing effect in the liquid oxygen fracturing process,this paper presents the thermal analysis results and gas precipitation characteristics of five liquid oxygen fracturing adsorbent materials under oxygen and nitrogen atmosphere.In this paper,the thermal analysis results and gas precipitation characteristics of the five liquid oxygen fracturing adsorbent materials under oxygen and nitrogen atmospheres were analysed by thermogravimetric frequency infrared(TG-FTIR)analyser,and the pyrolysis process of the better liquid oxygen fracturing adsorbent materials under different oxygen concentrations was analysed by separate comparison.The results show that the pyrolysis effect of the liquid oxygen fracturing adsorbents is better under oxygen atmosphere,and the different gas flow rates have certain effects on the pyrolysis of the liquid oxygen fracturing adsorbents;the weight loss ratio is the indicator of the material preference,and the order of preference is carbon powder,carbon rods,sponges,foamed carbon and wood cellulose;the results of the research provide certain technical references for the liquid oxygen fracturing technology.
