摘　　要：煤沥青用四氢呋喃萃取分离得到四氢呋喃可溶物(THFS)和四氢呋喃不溶物(THFI)。在沥青和THFS及THFI中分别加入一定量的镍、钙催化剂后于不同温度下进行碳化,用XRD等检测手段表征碳化产物中的石墨晶体,结果表明,THFS是制备电磁屏蔽材料的良好原料。Coal pitch is extracted with tetrahydrofuran to obtain tetrahydrofuran soluble （THFS） and tetrahydrofuran insoluble （THFI）. A certain amount of nickel and calcium catalysts are added into pitch, THFS and THFI respectively and then carbonized at different temperature, the graphite crystal in carbon products is detected with X- ray detection , the result shows that THFS is a good raw material for production of electromagnetic screening material.
