Advantage
Activated Alumina For Catalyst (A-AS-C)
This type is made up of spheres of promoted activated alumina with large surface areas and specifically engineered pores. Often used in combination with A-AS-DS activated alumina, this product can catalyze the Claus process. The Claus process converts undesirable hydrogen sulfide and other compounds to elemental sulfur.
A-AS-C Claus Catalyst Available Products:
Product | Catalyst | Size |
A-AS-DS | Activated Alumina | 3/16″ |
We offers the most extensive line of Claus catalysts in the industry.
Improved resistance to deactivation from sulfation in all phases of the Claus process
Better COS decomposition in the 1st catalytic converter
Effective catalyst life can be prolonged by a factor of 3

Application
A-AS-04 activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in
a way that produces a highly porous material;
A-AS-DF activated alumina is also widely used to remove fluoride from drinking water. Basically,
the more alumina in the filter, the less fluoride will be in the final, filtered water.
A-AS-MS is for absorbent H2O2
A-AS-AC is for chlorine absorbent
A-AS-C in hydrogen peroxide production, as a selective adsorbent for many chemicals including,in removal from gas streams .
A-AS-A activated alumina is used as a charge material in foreline traps to prevent generated by from
backstreaming into the system
Industry standard HG/T39272007 Activated Alumina is issued by UNION ALKALIES & CHEMICALS GROUP LTD
