化工行业中反应器的定态稳定性问题,是引人注目的研究课题,但从热力学角度研究,却是少见的。本文应用非平衡热力学理论进行了新的探索和尝试。 一、CSTR的数学模型及定态解 考虑放热反应: 1.5H_2+0.5N_2(?)NH_3假定反应在连续搅拌式反应器(CSTR)中进行,内部变量均匀。为简化,不计流体粘性作用及催化剂物性影响,并假设反应前后压力维持不变。
The chemical industry reactor steady-state stability problems, is an attractive research topic, but from the thermodynamic point of view, it is rare. In this paper, a new exploration and attempt are made using the theory of non-equilibrium thermodynamics. First, the mathematical model of CSTR and stationary solution Consider the exothermic reaction: 1.5H_2 + 0.5N_2 (?) NH_3 Assuming the reaction is carried out in a continuous stirred reactor (CSTR), the internal variables are uniform. To simplify, regardless of fluid viscous effects and physical properties of the catalyst, and assuming the pressure before and after the reaction remained unchanged.
