考察了工业萘中脱除杂原子氮的动力学,其反应速度可用Langmuir-Hinshel-wood 模型表示,其碱氮的脱除为表观一级反应。在经简化整理后的动力学方程C=C_(?)e~(-kt)中,在290℃、320℃、350℃下,k 值分别为0.5398,0.7958和1.2411。脱氮反应的表观活化能为11.2 kcal/mol。本文还探讨了工业萘加氢精制的主要付反应萘加氢生成四氢萘的过程。萘加氢生成四氢萘是可逆一级反应,其动力学方程为:x=x_e(1-e~(-kt))。在动力学方程中,290℃、320℃、350℃下的平衡浓度和k 值分别依次为0.9534、0.1659;0.8359、0.5291;0.5868、1.8631。正向反应的活化能为22.5 kcal/mol。
The kinetics of the removal of heteroatom nitrogen from industrial naphthalene was investigated. The reaction rate can be expressed by the Langmuir-Hinshel-wood model, and the removal of nitrogen is an apparent first-order reaction. In the simplified kinetic equation C = C _ (?) E ~ (-kt), k values were 0.5398, 0.7958 and 1.2411 at 290 ℃, 320 ℃ and 350 ℃ respectively. The apparent activation energy of denitrification is 11.2 kcal / mol. This paper also discussed the industrial naphthalene hydrofinishing the main pay reaction naphthalene hydrogenation process to produce tetralin. Hydrogenation of naphthalene to tetrahydronaphthalene is a reversible first-order reaction, and its kinetic equation is: x = x_e (1-e ~ (-kt)). In the kinetic equation, the equilibrium concentration and k value at 290 ℃, 320 ℃ and 350 ℃ were 0.9534, 0.16659, 0.8359, 0.5291, 0.5868 and 1.8631 respectively. The activation energy of the forward reaction is 22.5 kcal / mol.
