HG/T 3927-2020 Activated aluminium oxide for industrial use
1 Scope
This standard specifies the classification, requirements, test methods, inspection rules, marking and labeling as well as packaging, transportation and storage of activated aluminium oxide for industrial use.
This standard is applicable to the activated aluminium oxide for industrial use. This product is used in oil refining, chemical fertilizer, petrochemical, natural gas, oxygen production and chemical industry, etc. It is mainly used as gas and liquid adsorbent, fluorine adsorbent, chlorine adsorbent, desiccant and catalyst carrier.
