GB/T 31583-2015Test method of physical properties for deoxidizing protection type (English PDF)

1 Scope

This standard specifies the bulk density deoxy-protective sulfur recovery catalyst particles point crush strength, attrition rates, and surface area, pore

Volume, average pore diameter of the measuring method.

Claus sulfur recovery process of this standard applies to the acidic hydrogen sulfide gas as raw material, the alumina as the main active ingredient having

Deoxy protection sulfur recovery catalyst.
