Description

不粘性烟煤低温干馏制取工业气化型煤的方法
本发明涉及工业化型煤的生产技术领域，具体涉及一种采用不粘性烟煤低温干馏制取工业气化型煤的方法。
目前市场上制取工业气化型煤大都采用无烟粉煤或焦末为主要原料，而无烟粉煤或焦末在自然界贮量十分有限，不能适应大规模工业生产需求，而不粘性烟煤因其挥发分高，粘度差等不能作为工业气化原煤，本发明将自然界贮量巨大的不粘性烟煤，经低温干馏收取粗煤气、焦油、烯烃后制成半焦，经固定床常压间隙气化炉试烧，其气化特征为：有较高的低温反应活性，但热稳定性、抗破碎强度、灰熔点和气化强度均达不到工业生产的需求，具体试烧数据如下：
化学反应值：
                 800℃    α＝11.5％
                 850℃    α＝22.5％
                 900℃    α＝37.0％
                 950℃    α＝61.5％
                 1000℃   α＝78.7％
                 1100℃   α＝90.2％
灰熔点                          ℃
                              DT＜1050
                              ST＜1100
                              FT＜1200
抗破碎强度                    SS＜81％
热稳定性                      TS+6＜80～70％
气化强度                      550～650M3/m2h
发热量                        20000～30000KJ/kg
煤气成份                      CO2    mol％＜13
                              H2     mol％＜50
                              CO     mol％＜29
                              O2+Ar  mol％＜0.13
                              N2    .mol％＜7
本发明的目的是提供一种工业气化型煤制取的新方法，采用不粘性烟煤为原料，其工业分析：
    含碳量                 60～90％
    挥发分                 20～40％
    灰分                   10～40％
    水分                   3～15％
    低位发热量             11000～20000KJ/kg
经过低温干馏技术制得半焦，并进一步加工处理，制成工业气化型煤，取代价格较高的无烟煤和冶金焦等工业气化原料，适应大规模、产业化生产的需求。
为实现上述目的，本发明的技术解决方案如下：不粘性烟煤经破碎筛选后进行低温干馏，炉料上部收取粗煤气，焦油和稀烃后，余料水淬后获得半焦，再经机械方法粉碎，加入适量非腐植酸钠粘结剂和高熔点添加剂搅拌均匀，挤压成型，制成一定型状的型煤制品，最后经烘干(干燥)出厂。
采用以上生产工艺制成的工业气化型煤，不仅具有较高低温反应活性，而且具有较高的热稳定性，抗破碎强度，灰熔点和气化强度。下面通过对图1本发明的工艺过程作进一步详细说明，图1为本发明的工艺流程图。
