水性中间相沥青的制备工艺改进研究

he preparation of aqua-mesophase pitch (AMP) was investigated by oxidation of high temperature coal tar pitch with mixtures of concentrated sulfuric acid and nitric acid. Improving the preparing process，the more cost-effective and high-yield method was used to prepare AMP. the property of the AMP and the morphology of the nano carbon poweders prepared by the AMP were studied in detail. Using the FT-IR spectra and TEM to characterize the raw material, AMP and the nano carbon powders. The results reveal that the shructure of the AMP produced by the improved process didn’t changed and particle size of the nano carbon powders prepared with this AMP is smaller than that prepared before and with a uniform particle size.
