Abstract: Low-temperature pyrolysis of tar -rich coal to produce tar is a way of clean and efficient utilization of coal resources. This paper studies the influence of tar-rich coal production area(Zhangjiamao, Ningtiaota, Hongliulin), particle size, final pyrolysis temperature, heating rate, pressure and different industry analysis of tar-rich coal on tar yield. The quality of tar is analyzed by gas chromatography simulated distillation. The results showed that under the conditions of particle size of 0.8-2mm, final pyrolysis temperature of 550℃, pressure of 0.1Mpa, and heating rate of 26℃/min, Zhangjiamao's tar-rich coal has the largest tar yield of 13.19%. The yield of tar increases with the increase of volatile matter, hydrogen content and H/C of tar-rich coal.
