NB/SH/T 0959-2017 《Determination of catalyst specific surface area by static nitrogen adsorption method in catalytic cracking》 Related products

Standard NB/SH/T 0959- -2017 specifies the use of static nitrogen adsorption capacitance method to determine the total specific surface area and micropore specific surface area of catalytic cracking catalysts. It is suitable for catalytic cracking catalysts, catalytic cracking catalysts and auxiliaries containing micropores and mesopores. The standard emphasizes the need to establish appropriate safety and protective measures before use, and to ensure the applicability of relevant regulatory restrictions. The normative reference documents referred to include GB/T 6379.2 (Measuring method Precision) and GB/T 21650.2-2008 (Determination of pore size distribution and porosity of solid materials by gas adsorption method).
