UOP 815-87 is a laboratory test method for Acid Insolubles in Catalysts, giving technical teams a focused way to evaluate insoluble material associated with catalyst samples. For buyers reviewing UOP 815-87, the value is in its narrow, practical scope: it supports catalyst quality assessment, sample comparison, and routine analytical documentation in refinery and petrochemical settings. The method is especially relevant where catalyst condition, contamination, or recovered solids need to be reviewed with consistent laboratory practice. It is a useful reference for analysts and reviewers who need a standards-based approach to this specific catalyst property.

What is UOP 815-87?

UOP 815-87 is a UOP Test Method centered on the determination of acid insolubles in catalysts. In practical laboratory terms, it provides a defined way to evaluate the insoluble fraction associated with a catalyst sample, helping users characterize material that does not dissolve under the method’s specified conditions. As an analytical method, it is intended to support consistent measurement and comparison rather than broad materials characterization. That makes it relevant for organizations that rely on standardized catalyst testing and clear technical documentation.

Where is UOP 815-87 used?

UOP 815-87 is commonly used in catalyst laboratories, refinery quality control groups, and technical review workflows where catalyst samples must be checked against a standard method. It may also support analytical chemists, laboratory analysts, and process or technical engineers involved in catalyst evaluation, sample receipt, or performance review. In practice, it fits environments where catalyst condition or insoluble residue needs to be documented in a repeatable way for internal comparison, quality tracking, or method-based reporting.

Why is UOP 815-87 important?

This method matters because acid insolubles can be a useful indicator in catalyst handling, evaluation, and quality oversight. UOP 815-87 helps teams apply a consistent laboratory approach, which supports clearer comparisons between samples and more dependable technical records. For organizations managing catalyst testing programs, it can improve confidence in review decisions, reduce ambiguity in documentation, and align laboratory results with established UOP practice. That makes it valuable for routine QA/QC use and for technical teams that depend on reliable, standardized catalyst data.
