UOP 294-93 is a technical laboratory method for determining the apparent bulk density of catalyst particles. For buyers reviewing catalyst quality or comparing material lots, this method helps define how the particles pack and how that material may behave in handling, storage, and process use. In refinery and petrochemical settings, apparent bulk density is a practical property for catalyst evaluation because it supports specification checks, batch comparison, and internal documentation. UOP 294-93 is therefore relevant to laboratory analysts, QA/QC personnel, and technical reviewers who need a clear, standard reference for catalyst characterization.

Overview of UOP 294-93

This UOP Test Method focuses on a measurement of apparent bulk density rather than a compositional analysis. As a standards document, UOP 294-93 is used to support consistent laboratory evaluation of catalyst particles under a defined method framework. The title indicates a property-based test that can be used when comparing catalyst materials, confirming lot consistency, or documenting product characteristics for technical records. For organizations that manage catalyst supply, receive materials into a plant, or review laboratory data, the method provides a practical basis for standardized density determination.

Laboratory use of UOP 294-93

UOP 294-93 may be used in catalyst laboratories, refinery quality control groups, and technical teams involved in catalyst selection or acceptance review. It is especially relevant where catalyst particles must be evaluated for packing behavior, handling characteristics, or comparison between batches. Laboratory analysts and process or technical engineers may use the method data to support material review and internal specifications. Because it is centered on a physical property of catalyst particles, the method fits routine laboratory workflows where clear, repeatable documentation is important for plant support and product evaluation.

Why UOP 294-93 matters in day-to-day work

In day-to-day operations, apparent bulk density data can help teams compare catalyst lots with greater confidence and keep quality checks aligned across laboratory and plant functions. UOP 294-93 supports consistent reporting, which is important when technical reviewers need to assess whether a material matches expected handling or inventory characteristics. It also adds structure to laboratory records, making it easier to track changes over time and support procurement, acceptance, or internal review decisions. For organizations working with catalyst materials, that kind of clarity can improve communication between lab staff, QA/QC teams, and engineering groups.
