Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 10504-2008 "3A molecular sieve", compared with GB/T 10504-2008, the main technical changes are as follows.
--- Improve some of the main technical requirements of the product (see Chapter 4);
--- Modify spherical 3A molecular sieve and hollow glass spherical 3A molecular sieve specifications (see 4.3 and 4.4);
--- Increasing the spherical glass 3A molecular sieve gas desorption amount, powder falling and temperature rise technical requirements (see 4.4);
--- Remove the hollow glass with spherical 3A zeolite wear rate and crushing resistance of the technical requirements (see 4.4);
--- Modify the hollow glass with spherical 3A molecular sieve adsorption of static water test conditions (see 5.4).
This standard proposed by the China Petroleum and Chemical Industry Federation.
