Abstract: Shendong coal is a typical Jurassic non stick coal,which has the advantages of low ash,low sulfur,low phosphorus,low potassium and sodium content,high tar yield,high volatile yield,medium grindability index and thermal stability. It is more suitable for medium and low temperature pyrolysis processing. In order to study the pyrolysis characteristics of Shendong coal comprehensively,thermogravimetric analyzer and 40 kg pyrolysis unit were used to study the formation and properties of tar,pyrolysis gas and char of Shendong coal. The results show that excellent coal qualities with high tar yield are found of Shendong coal,which makes it suitable for upgrading in medium-low temperature pyrolysis. With the increasing of pyrolysis temperature,the yield of pyrolysis gas increases significantly while the yield of char decreases gradually. The content of volatile matter in char decreases rapidly,while the content of carbon increases gradually. The mechanical strength of char degrades gradually. The reactivity and grindability of char decrease while the specific resistance decreases rapidly. The specific surface and the phenol adsorption capacity of char are relatively low. Excellent properties are found of pyrolysis tar,which makes it suitable for hydrogenation to prepare clean fuel.
