摘要

摘要: 利用高频电炉对神府煤进行快速热解,研究了不同热解温度和停留时间下,固相和气相产物的性质。结果表明,煤焦的失重率及真密度随温度升高和时间的延长而增长。红外光谱结果表明,热解过程中,煤中含氢/含氧官能团分解,生成H₂、CO、CO₂、CH₄等气体,并且其分解程度随温度的升高和时间的延长而加深。气相产物中H₂和CO的释放量随温度的升高和时间的延长而增加,而CO₂和CH₄存在释放量的峰值。气相产物随温度的升高和时间的延长而增多,导致高温煤焦出现大量的孔隙和裂缝。

Abstract: A high-frequency furnace was utilized to carry out rapid pyrolysis of Shenfu coal. The effect of temperature and residence time on the properties of solid and gas products was studied. The results show that the mass loss and true density of the char increase with increasing of both temperature and time. The analysis of their infrared spectra indicates that the hydrogen/oxygen functional groups decompose to form H₂, CO, CO₂, CH₄ and other gases during pyrolysis, and the decomposition increase with increasing temperature and time. The emission of H₂ and CO monotonically increases, however there are emission peaks for CO₂ and CH₄. The total gas products increase with temperature and time, leading to the pores and cracks on the char after high temperature pyrolysis.
