UOP 254-87 is a laboratory test method for determining the apparent bulk density of fluid cracking catalyst. For buyers reviewing refinery and catalyst laboratory standards, this method helps define how a catalyst sample behaves in a bulk state, which is important for handling, storage, and comparison across lots or suppliers. Because apparent bulk density can affect how material is measured, transferred, and evaluated, the method supports practical quality assessment in catalyst-focused operations. UOP 254-87 is a useful reference for teams that need consistent laboratory documentation and a clear basis for sample evaluation.

Purpose of UOP 254-87

The purpose of UOP 254-87 is to provide a standardized way to measure the apparent bulk density of fluid cracking catalyst under controlled laboratory conditions. As a UOP test method, it is intended to support consistent analytical evaluation rather than informal observation. The method is relevant when technical teams need a repeatable density result for catalyst characterization, product comparison, or internal quality checks. In refinery and catalyst labs, this type of measurement helps align testing practices and gives analysts a defined method for documenting material behavior in a way that supports review and decision-making.

Laboratory use of UOP 254-87

UOP 254-87 is typically used in catalyst laboratories, refinery quality control groups, and technical teams responsible for fluid catalytic cracking materials. Laboratory analysts may use it during incoming material checks, batch comparison, or routine verification of catalyst properties. It is also relevant to petroleum specialists, process engineers, and technical reviewers who need a dependable method reference for evaluating catalyst consistency. In practical lab workflows, the method supports structured sample review and helps ensure that density-related results are recorded in a way that is suitable for internal reporting and specification-based assessment.

Practical importance of UOP 254-87

The practical value of UOP 254-87 lies in its role as a clear, standardized measure of apparent bulk density for fluid cracking catalyst. For day-to-day laboratory and refinery use, that helps reduce uncertainty when comparing samples, reviewing supplier material, or checking whether catalyst properties are staying consistent over time. It also supports better documentation for QA/QC and technical review, where repeatable results are often needed to guide material acceptance or further evaluation. For organizations working with FCC catalyst, the method adds clarity to an important handling and characterization property.
