UOP 964-11 is a laboratory method for evaluating the surface area, pore volume, average pore diameter, and pore size distribution of porous materials by nitrogen adsorption. It helps technical teams characterize how a material is structured at the pore level, which can be important when selecting, comparing, or reviewing catalyst supports, adsorbents, and related porous solids. For buyers working in petroleum, refining, or chemical laboratories, this method supports informed material assessment and consistent technical documentation. UOP 964-11 is especially relevant where pore structure can influence performance, quality, or process suitability.

Purpose of UOP 964-11

The purpose of UOP 964-11 is to provide a standardized way to measure key textural properties of porous materials using nitrogen adsorption. The method focuses on determining surface area and pore structure metrics that are commonly used in material characterization and analytical review. In practice, this type of UOP test method helps laboratories apply a consistent framework for comparing samples and documenting results. It is a practical analytical tool for situations where pore characteristics need to be understood in a controlled, repeatable way.

Laboratory use of UOP 964-11

UOP 964-11 is commonly used in analytical laboratories that support refinery, petrochemical, and materials evaluation work. Laboratory analysts, technical reviewers, and quality-focused teams may use it when assessing porous solids for development, qualification, or routine comparison. The method is relevant where surface area and pore size distribution are important to performance review, particularly for catalyst-related or adsorbent-related materials. It also supports laboratory workflows that require clear, standardized documentation for internal review or supplier comparison.

Practical importance of UOP 964-11

In day-to-day technical work, UOP 964-11 helps convert pore structure into measurable data that can support product comparison and quality decisions. Surface area and pore volume are often tied to how a porous material behaves in service, so having a recognized method improves consistency across samples and teams. This makes the method useful for refinery QA/QC groups, laboratory personnel, and technical specialists who need dependable analytical results for review, specification support, or material selection. UOP 964-11 also helps strengthen documentation quality in controlled laboratory environments.
