碳二加氢等温反应过程模拟与操作参数优化
Simulation and optimization of operating parameters of isothermal reaction process for acetylene hydrogenation
摘要
Abstract
With the study object of an acetylene hydrogenation reactor with isothermal tubular fixed bed, this paper used computational fluid dynamics (CFD) method to establish the two-dimensional homogeneous flow reactor model that had heat exchange with the outside. By adding the solid-gas energy equations, the heat exchange model of porous medium zone and two-temperature model of gas-solid coupled heat transfer are established. The genetic algorithm was used to fit reacting kinetic parameters. And the ratio of hydrogen acetylene ration (H2/C2H2) and the cooling temperature were optimized to meet the maximum of reaction selectivity. Simulation results show that the optimal hydrogen acetylene ratio is 1.18 and the optimal cooling temperature is 334.66 K. Finally, based on the simulation and optimization results, the effects of the hydrogen acetylene ratio and the cooling temperature on the selectivity of acetylene hydrogenation reaction were analysed, and therefore they provide an important significance for improving the operating performance of acetylene hydrogenation reactor.关键词
