NB/SH/T 0950-2017 in English

The industry standard NB/SH/T 0950-2017, titled "Determination of Lanthanum Oxide and Cerium Oxide Content in Catalytic Cracking Catalysts by X-Ray Fluorescence Spectrometry," was issued on December 27, 2017, and came into effect on June 1, 2018. This standard specifies a method for determining the content of lanthanum oxide (La₂O₃) and cerium oxide (CeO₂) in catalytic cracking catalysts using X-ray fluorescence spectrometry (XRF).

Catalytic cracking catalysts are essential in the petroleum refining process, where they facilitate the breakdown of large hydrocarbon molecules into smaller, more valuable products. The presence of lanthanum and cerium oxides in these catalysts can significantly influence their performance, stability, and overall efficiency. Therefore, accurate measurement of these oxides is crucial for quality control and optimization of the catalytic cracking process.

The XRF method outlined in this standard offers a reliable and efficient approach for quantifying La₂O₃ and CeO₂ in catalytic cracking catalysts. The procedure involves sample preparation, calibration with standard reference materials, and analysis using XRF instrumentation. The method is designed to provide precise and reproducible results, ensuring consistency across different laboratories and industries.

By adhering to this standard, manufacturers and researchers can ensure that the catalytic cracking catalysts meet the required specifications, thereby enhancing the efficiency and reliability of the refining process. The standard serves as a valuable tool for the petroleum and chemical industries, promoting uniformity and accuracy in the measurement of critical catalyst components.
