摘要: 利用常压微型固定床反应器,采用CuZnZrAIO 甲醇重整制氢催化剂,考察了503 -543K 下甲醇停留时间(W/FAO ) 对CO2 和CO 转化率的影响,在排除内外扩散影响的条件下,采用甲醇直接重整和甲醇分解平行进行的反应途径,以CO 和CO2 为关键组分,建立了适合其在甲醇蒸汽重整制氢反应中使用的动力学模型,并利用最小二来法确定了模型参数. F-检验表明所提出的动力学模型可作为反应器模拟分析和设计的基础.

Abstract:

The methanol steam reforming was performed using a micro fixed-bed reactor at atmospheric pressure ,with CuZnZrAIO as the catalyst , and the effects of pseudo residence time W / F AO on the conversions of methanol to outlet CO and CO2 were investigated at 503 - 543 K. By carrying out the direct methanol reforming and the methanol decomposition in parallel , a kinetic model suitable for the parallel reaction route was then established on the condition that the effects of intemal and extemal diffusing were eliminated , with the outlet CO and CO2 as the two key indexes. Moreover , the corresponding model parameters were determined by means of the least square method. The F-test demonstrates that the proposed kinetic model is suitable for the simulation and design of the reactor for methanol steam reforming.
