HG/T 6149-2023 is the English-translated version of 加氢催化剂及其载体中二氧化硅晶相含量的测定 X射线衍射法.
HG/T 6149-2023 describes the X-ray diffraction method for determining the silica crystal phase content of hydrogenation catalysts and their supports. The chemical industry standard applies to contents between 0.33 % and 10.22 % by mass. The page adds that the determination of the low-temperature cristobalite crystal phase in hydrogenation catalysts and their supports may also follow the standard, although its precision has not been examined for that case. The Ministry of Industry and Information Technology issued the standard on 21 April 2023 and it took effect on 1 November 2023.

This standard specifies the use of X-ray diffraction method to determine the content of silica crystal phase in hydrogenation catalysts and their carriers. This standard is applicable to the determination of the ��-silica crystal phase content in hydrogenation catalysts and their carriers in the range of 0.33% to 10.22% (mass fraction). The determination of low-temperature cristobalite crystal phase content in hydrogenation catalysts and their carriers can also refer to this standard, but this standard does not examine its precision.
