阐述了燃烧脱氧、催化氧化、化学吸收法等3种脱氧机理,主要综述了贵金属、铜系、铁系、锰系、钼系以及多孔陶瓷材料等相关脱氧剂的制备工艺、脱氧原理和研究现状。通过对比不同脱氧剂的制备成本以及脱氧效果、后处理程序等,指出各种脱氧剂的优缺点。其中贵金属脱氧剂脱氧效果最好,但消耗甲烷、氢气等还原气体,且产生CO2/H2O等杂质;非贵金属脱氧剂价格低廉,但脱氧效果略差,使用温度相对较高;非金属型脱氧剂具有不易硫中毒等优缺点。最后,综合前述脱氧剂的特点,提出脱氧剂的两个发展方向,即非金属脱氧剂和具有较强吸附、催化性能的复合型脱氧剂。

This article elaborates on three deoxidation mechanisms, including combustion deoxidation, catalytic oxidation, and chemical absorption. It mainly summarizes the preparation processes, deoxidation principles, and research status of deoxidants for precious metals, copper based, iron based, manganese based, molybdenum based, and porous ceramic materials. By comparing the preparation costs, deoxidation effects, and post-treatment procedures of different deoxidizers, the advantages and disadvantages of each deoxidizer are pointed out. Among them, noble metal deoxidizers have the best deoxidation effect, but they consume reducing gases such as methane and hydrogen, and produce impurities such as CO2/H2O; Non precious metal deoxidizers are inexpensive, but their deoxidation effect is slightly poor and their usage temperature is relatively high; Non metallic deoxidizers have advantages and disadvantages such as being less prone to sulfur poisoning. Finally, based on the characteristics of the aforementioned deoxidizers, two development directions for deoxidizers are proposed, namely non-metallic deoxidizers and composite deoxidizers with strong adsorption and catalytic properties.
