A Catalyst COA (Certificate of Analysis) is the core technical document for quality traceability of each batch of catalyst products. It is also a mandatory certificate for catalyst foreign trade communication, customer qualification review, factory feeding & production, and cross-border import & export customs clearance.
Formal quality analysis reports for industrial catalysts mainly consist of four core sections: batch traceability information, chemical composition testing, physical property testing, and inspection result judgment. The industry strictly follows the "one batch, one certificate" specification; no universal template is applicable, and the batch information stated on the report must fully match the delivered products.
Batch traceability information forms the foundation to verify the validity of the report, covering key details such as product model, production lot number, manufacturing date, inspection date, and applicable quality standards. Currently, industry-implemented standards fall into three categories: national standards, industrial standards and customized enterprise standards. Each standard carries distinct parameter limit values, which directly determine product compatibility with working conditions including petroleum refining, coal chemical industry and environmental governance. These standards also serve as critical basis to avoid quality disputes between suppliers and buyers.
Chemical composition test data dictates the core catalytic performance of catalysts. Contents of primary active components including nickel, molybdenum, cobalt, platinum and palladium directly affect feedstock conversion efficiency. Deviations from standard ranges will lead to substandard reactions or excessive by-product generation. Rare earths and alkaline additives improve the catalyst's thermal stability and strengthen its resistance to sintering and impurity poisoning. Harmful impurities such as sulfur, arsenic, sodium and iron require rigorous control; trace excess will trigger rapid catalyst deactivation.
Physical property indicators directly govern the actual operation status of industrial plants. Specific surface area, pore volume and pore size structure determine reactant adsorption and diffusion effects, laying the groundwork for stable catalytic activity. Bulk density impacts reactor loading volume and operating costs, while crushing strength and attrition resistance reflect the catalyst's capacity to withstand impact and pulverization. Substandard physical properties will cause elevated pressure drop across reactor beds and uneven gas flow distribution, potentially triggering unplanned shutdowns of production facilities in severe cases.
The quality inspection report reflects static sampling test results, which only judge compliance with product specifications. Actual service performance shall be comprehensively evaluated by combining operating conditions such as reactor temperature, pressure, feed velocity and raw material quality.
