A Study on Kinetics Model of Coal Liquefaction Process

ZOU Gang-ming,LI Hai-bin(1.Maoming College,Maoming 525000,China;2.Taiyuan University of Technology,Taiyuan 030024,China)  
In the paper, the pyrogenation character and kinetics of coal are discussed. From molecule structure of coal, coal reaction character is described by aromatic ring . Kinetics model of coal pyrogenation can be obtained by analysing the data of TGA experiment according to log〔-log(1-a)〕=log(AE/Rφ)-0.054E/T-2.284. The result shows that coal pyrogenation reaction includes three one-order reactions,namely two pyrogenations and one polycondensation. On calculating pyrolysis characteristic values of coal , apparent activation energy(Ea) of various stages, reaction kinetics constant (K), pre-exponent (A) , maximum weightlessness rate(Rm), weight loss percent (F), reaction active index(Ra),they can be regarded as the index of coal pyrolysis reactive activity .The bigger Ra or Rm, the better reactive activity of coal .The value of Tb(initial reaction temperature) and Tf(final reaction temperature) is defined through the curves of TG and DTG . It decides the upper limit of reaction temperature of routine and high temperature rapid liquefaction . Thus, the section of coal liquefaction reaction temperature is 390-480℃ of Yang cun coal and 425-525℃ of Sheng mu coal separately .
