Standard Practice for Determination of the Six Major Rare Earth Elements in Fluid Catalytic Cracking Catalysts, Zeolites, Additives, and Related Materials by Inductively Coupled Plasma Optical Emission Spectroscopy

Importancia y uso:

5.1 The chemical composition of catalysts and catalyst materials is an important indicator of catalyst performance and is a valuable tool for assessing parameters in a FCCU process. This practice will be useful to catalyst manufacturers and petroleum refiners for quality verification and performance evaluation, and to environmental authorities at the state and federal levels for evaluation and verification of various compliance programs (1, 2, 3).
