八氢菲选择性催化裂化反应动力学

在小型固定流化床(FFB)反应器中，消除内、外扩散影响，考察了八氢菲在选择性催化裂化（HSCC）催化剂上，470~515℃裂化发生环烷环开环反应以及脱氢缩合反应的动力学规律。在给出八氢菲催化裂化反应途径的基础上，建立了八氢菲裂化双曲线型Langmuir Hinshelwood（L H）六集总动力学模型，其中八氢菲裂化环烷环开环反应活化能为7063 J/mol，而其脱氢缩合反应活化能为4871 J/mol。残差检验和统计检验结果表明，所得动力学模型合理、可靠，能够真实反映八氢菲选择性催化裂化反应特性。

Kineticsof OctohydrophenanthreneHighly Selective Catalytic Cracking

The kinetics study on catalytic cracking of octohydrophenanthrene over highly selective catalytic cracking (HSCC) catalyst at temperature in the range of 470-515℃, in which the internal and external diffusion effects are eliminated, was carried out in a small fixed fluidized bed (FFB) unit. On the basis of cracking reaction pathway, the six lumping kinetic model of Langmuir Hinshelwood (L H) type for describing the octohydrophenanthrene catalytic cracking was developed. The activation energy of the naphthenic ring opening reactions of octohydrophenanthrene is 7063 J/mol, while that of  dehydrogenation condensation reactions is 4871 J/mol. Residual error distribution and statistical test show that the developed models are acceptable and reliable, which actually reflects the characters of octohydrophenanthrene HSCC.
