NB/SH/T 0943-2017 in English

The industry standard NB/SH/T 0943-2017, titled "Determination of FCC Catalyst Abrasion Resistance by Air Jet Method," was published on December 27, 2017, and came into effect on June 1, 2018. This standard specifies the method for determining the abrasion resistance of Fluid Catalytic Cracking (FCC) catalysts using the air jet technique. FCC catalysts play a crucial role in the petroleum refining process, particularly in the conversion of heavy hydrocarbon fractions into lighter, more valuable products such as gasoline and diesel.

The air jet method outlined in this standard involves subjecting the catalyst particles to a high-velocity air stream to simulate the mechanical stresses they would encounter in an actual FCC unit. The degree of attrition or abrasion is then measured to assess the catalyst's durability and performance. This method is essential for ensuring that the catalysts can withstand the harsh conditions of the FCC process, thereby maintaining operational efficiency and reducing downtime due to catalyst degradation.

By providing a standardized procedure for evaluating FCC catalyst abrasion resistance, NB/SH/T 0943-2017 helps manufacturers and refineries to select and optimize catalysts that offer both high activity and mechanical strength. This, in turn, contributes to the overall efficiency and sustainability of the petroleum refining industry.
