| 摘 要： | 为了优化粉煤热载体干馏过程参数,通过粉煤热载体干馏热力学模型的建立,探寻粉煤干馏的主要影响因素,采用热重分析确定粉煤的热解温度区间.研究了粉煤粒径、热载体温度、干馏温度和干馏时间对干馏产物半焦挥发分的影响.结果表明：粉煤粒径和热载体温度对产物挥发分影响甚微,干馏温度和干馏时间对产物挥发分影响显著;产品挥发分基本随着干馏时间的延长而降低,随着干馏温度的升高,产品挥发分迅速降低.

| Abstract: | To optimize the process parameters for destructive distillation of pulverized coal by heat carrier,a thermodynamic model was established by a mathematical derivation.The main influencing factors were determined.The range for the pyrolysis temperature was obtained by a thermo gravimetric analysis(TGA).The effects of pulverized coal size,heat carrier temperature,destructive distillation temperature and destructive distillation time on the semicoke volatile of destructive distillation products were investigate... |
