Scope

NB/SH/T 0955-2026 is the English-translated version of 催化裂化催化剂孔体积的测定水吸附法.

NB/SH/T 0955-2026 is the Chinese standard "Standard test method for pore volume of catalytic cracking catalysts by water titration". This standard specifies a method for rapidly determining the pore volume (vp) of a catalytic cracking catalyst by a water droplet method.

This standard applies to catalytic cracking catalysts, catalytic cracking catalysts and additives. The measurement range of the droplet volume of the water droplet is 0.25 mL/g to 0.45 mL/g, and the method can also be used for the measurement of the pore volume exceeding this range, but the precision has not been examined.

It was issued by National Energy Administration. Issued on 2017-12-27, in force from 2018-06-01. It cites 4 other standards.
