Standard Practice for Sample Preparation of Fluid Catalytic Cracking Catalysts, Catalytic Materials, and Zeolites for Elemental Analysis by Inductively Coupled Plasma Optical Emission Spectroscopy

Importancia y uso:

5.1 The chemical composition of catalyst 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.3^, 4^, 5

5.2 Catalysts and catalyst type materials are difficult to prepare for analysis by ICP, and although the techniques presented in this practice are common, there is wide variation among laboratories in sample pretreatment and digestion recipes. This practice is intended to standardize these variables in order to facilitate the utility of comparative data among manufacturers, refiners, and regulatory agencies.
