树皮残植煤为我国华南晚二叠世特殊煤种之一,具有高挥发份、低水分、高硫(尤其有机硫)、高熔融性、高溶胀性和高焦油产率等特点。针对树皮残植煤的研究,从上世纪30年代开始距今已有80余年,取得了一定进展。本文对树皮残植煤的研究进行了概括和总结,并基于此,对其进一步研究提出了建议。 Bark remnant coal is one of the late Permian special coal species in southern China, and has the characteristics of high volatility, low moisture, high sulfur (especially organic sulfur), high melting, high swelling and high tar yield. Research on bark remnants of coal has been more than 80 years since the 1930s and some progress has been made. This paper summarizes and summarizes the research on the bark coal residue, and based on this, puts forward some suggestions for its further research.
