NB/SH/T 0958-2017 in English

The industry standard NB/SH/T 0958-2017, titled "Determination of Mechanical Tap Density of Formed Catalysts and Catalyst Carriers," was issued on December 27, 2017, and came into effect on June 1, 2018. This standard provides a method for measuring the mechanical tap density of formed catalysts and catalyst carriers, which is a critical parameter in the evaluation of these materials' physical properties.

Mechanical tap density is an essential characteristic that influences the handling, storage, and performance of catalysts and their carriers in various industrial processes. The standard outlines a precise procedure for determining this property, ensuring consistency and reliability in measurements across different laboratories and industries.

The method involves filling a known volume of the catalyst or carrier material into a graduated cylinder and subjecting it to a specified number of taps. The volume of the material after tapping is measured, and the tap density is calculated based on the mass of the material and the final volume. This standardized approach helps in comparing the densities of different catalyst formulations and ensures that the materials meet the required specifications for industrial applications.

By providing a uniform method for tap density determination, NB/SH/T 0958-2017 aids in the quality control and development of catalysts and catalyst carriers, contributing to the optimization of catalytic processes in the energy sector.
