将工业普通氢气转化为六个9以上的高纯氢,常用的脱氧方法有活性氧化铜、钯/氧化铝、钯/分子筛、钯/碳纤维以及镍铬催化剂等。这些方法由于分别存在脱氧深度差、单位时间处理量少和易被硫化物中毒等缺点,在实际使用中受到限制。大连化物所在国内首先研制成功金属/半导体类型高效脱氧催化剂,通过调变催化剂的电子因素和金属/半导体界面特性,使其具有脱氧深度深、处理量大、使用范围宽和抗水、抗毒能力强等特点。该催化剂经两年多工业应用考察和技术鉴定认为主要性能指标
Common industrial hydrogen into more than six high-purity hydrogen 9, commonly used methods of deoxidation of activated copper oxide, palladium / alumina, palladium / molecular sieve, palladium / carbon fiber and nickel-chromium catalyst. These methods are limited in actual use due to the shortcomings of poor deoxygenation depth, less treatment per unit time, and susceptibility to sulfide poisoning, respectively. Dalian Chemical Products Co., Ltd. firstly developed a successful metal / semiconductor type high-efficiency deoxidation catalyst in China, which has the advantages of deep deoxidation depth, large processing capacity, wide range of use, water resistance and poison resistance by means of modifying the electronic factors and the metal / semiconductor interface characteristics of the catalyst Strong and so on. The catalyst after more than two years of industrial applications and technical appraisal that the main performance indicators
