Scope
This standard specifies the test method for the specific surface area of catalysts used in oil refining.
This standard is applicable to the determination of the specific surface area of catalytic cracking catalysts with micro-mesoporous structures, hydrogenation refining catalysts for distillate oil with mesoporous structures, and catalytic reforming catalysts using the static nitrogen adsorption capacity method. It is also applicable to other catalysts with similar structures.
