摘要
采用混酸(HNO3/H2SO4)氧化石油生焦,制备水性中间相;重点考察温度对氧化速度的影响。利用付立叶红外光谱对石油生焦、水性中间相和残渣进行了表征;结果表明:扩散是石油生焦氧化的速率控制步骤,其表现活化能为3.9kJ·mol-1。
The preparation of aqua - mesophase was investigated by the oxidation of petroleum raw coke with sulfuric acid and nitric acid. The major objective of this paper is to investigate the effect of temperature on oxidation rate.The petroleum raw coke、Aqua - mesophase and the sediment samples were characterised by a FI-IR spectrum, The results show that: maas transport appears to be responsible for establishing the overall oxidation rate;the apparent activation energy for the investigation was to be hot 3.9 kJ.mol-l..
