UOP 1039-20: Automated Loss on Ignition (LOI) Method

�� FREE PREVIEW (First 5 Pages) ✔ First 5 pages free to download · No email required · Full document available after purchase This UOP Method 1039-20 details a procedure for determining the loss on ignition (LOI) in air, using a specified ignition temperature and time, for fresh, regenerated, used, and spent catalysts, catalyst supports, and molecular sieves. It utilizes an automated Thermogravimetric Analyzer (TGA) and is quantitative down to 0.1 mass-%. The method accounts for components that volatilize during ignition, such as carbon, chlorine, and fluorine. The first five pages of the document are available for free preview. This method is essential for accurate catalyst analysis and quality control. It includes detailed instructions on instrument configuration, sample preparation, and data interpretation.
