甲醇水蒸气重整本征动力学和模拟研究
Intrinsic Kinetic and Simulation Study of Methanol Steam Reforming
摘要
Abstract
In order to resolve the limitation of the built-in catalyst database in Aspen simulations,a dual-rate kinetic model based on the Power Law(PL)formulation is proposed.The kinetic model is integrated into Aspen Plus for multi-process simulation of hydrogen production.By incorporating the influence of catalysts on the reactions during the simulation,a more realistic chemical process simulation is achieved.The dual-rate kinetic model accurately reflects actual hydrogen production conditions:increasing temperature and reducing liquid hourly space velocity(LHSV)both enhance methanol conversion and simultaneously increase CO selectivity.The steam-to-carbon molar ratio has a minor impact on the reaction.By considering energy consumption,the optimal range of the steam-to-carbon molar ratio is 1.0～1.4.Under the condition in which the reaction temperature is 280 ℃ and the feed flow rate is 1.5 mL/min,the multi-process simulation results demonstrate that the CO concentration in the product is reduced to only 6.89 μL/L after methanol steam reforming,water-vapor shift,and CO selective oxidation.This CO concentration meets the requirements for proton exchange membrane fuel cells(PEMFC).关键词
