煤焦油加工技术进展及工业化现状

研究了煤焦油的性质、组成、加工利用机理、加工工艺存在的问题等。指出高温煤焦油传统深加工今后工作重点是增加产品品种,提高产品质量。高温煤焦油加工利用的重点在于开发高活性催化剂,提高加氢转化率和燃料油回收率;中低温煤焦油加工利用以生产燃料油或燃料-化工型路线为主,后者为其产业化方向。 Properties and components of coal tar,as well as its processing and utilization mechanism,processing technique and issues existed in manufacturing process are analyzed.Increasing product type and guaranteeing quality of products are the main development direction of high-temperature coal tar traditional deep processing.The most important thing to processing and utilizing coal tar is to develop high active catalysts,improve hydrogenation conversion and recovery rate of fuel oil.Fuel oil production and fuel-chemical development are the main processing and utilization methods of medium-low-temperature coal tar,the latter should be industrialized
