摘要/Abstract

摘要： 以山西山阴低阶煤为原料,采用管式炉对低阶煤进行低温干馏提质研究,考察了干馏终温及恒温时间对干馏产物收率及性质的影响。结果表明,干馏的优化条件为温度500℃、恒温时间60min。此条件下半焦收率较高,且硫质量分数明显下降,脱硫率高达55.0%,挥发分、灰分质量分数及高位发热量均满足京津冀地区洁净燃煤质量指标中的规定,可作为洁净动力燃料用于供热、取暖等。焦油收率较高,且焦油密度小,轻质油质量分数高,沥青质质量分数低,可通过加氢处理得到优质燃料油。煤气产率高,可采用变压吸附技术制取H2。

Abstract: In this article, low temperature pyrolysis upgrading experiment was conducted with the low rank coal from Shanyin, Shanxi. The influence of temperature and holding time on the product yield and properties was investigated by tube furnace. The results showed that the optimized pyrolysis temperature of the experiment was 500~550 ℃，and holding time was 60 minutes. The semi-coke yield of the low rank coal was high, the sulfur content decreased significantly, and the desulfurization rate was up to 55%. The volatile matter, high ash content and higher heating value can meet the requirements of clean coal quality index in Beijing-Tianjin-Hebei region, and it can be used as clean fuel for heating, heating and so on. The tar yield was high, the density of tar was low, and the light oil component content was high. So, high quality fuel oil can be obtained through hydrogenation. The gas yield was high, and H₂ can be gotten using the produced gas as raw material by pressure swing adsorption technology.

Key words: Low rank coal, Low-temperature dry distillation;, Upgrading, Semi-coke
