| Catalyst Product Portfolio | 15% | Coverage of FCC, hydroprocessing, reforming, isomerization, alkylation, hydrogenation, and specialty refining catalysts. | A capable supplier should provide products matched to the refinery unit, feedstock properties, operating severity, and target product specification rather than offering one generic catalyst. | Technical product sheets, application list, catalyst formulation details, and unit-specific references with customer information appropriately anonymized. | 0–5 |
| Catalyst Performance | 20% | Activity, selectivity, conversion, product yield, temperature performance, pressure tolerance, and resistance to poisons such as sulfur, nitrogen, metals, or coke precursors. | Performance should be demonstrated through standardized laboratory testing and, preferably, commercial-unit results under comparable feed and operating conditions. | Independent test reports, pilot-plant data, commercial performance summaries, mass-balance results, and clearly defined test conditions. | 0–5 |
| Quality Consistency | 15% | Consistency of chemical composition, surface area, pore-volume distribution, particle-size distribution, crush strength, attrition resistance, and moisture content. | Acceptance limits should be defined for every critical quality attribute and verified for each production batch before shipment. | Certificate of analysis, batch-release records, sampling plan, control charts, and documented nonconformance procedures. | 0–5 |
| Manufacturing and Process Control | 10% | Control of impregnation, precipitation, calcination, activation, extrusion, spray drying, forming, and packaging processes. | The manufacturer should operate a documented quality-management system; ISO 9001 certification is useful evidence, but the certificate should be verified for scope and validity. | Valid certification, process-flow documentation, equipment list, internal-audit records, calibration records, and factory-audit results. | 0–5 |
| Technical Service and Application Support | 10% | Feedstock assessment, catalyst selection, loading calculations, start-up assistance, process monitoring, troubleshooting, and spent-catalyst analysis. | Strong suppliers provide engineering support before loading and performance follow-up during the catalyst cycle, including recommendations for operating changes. | Service-level agreement, technical staffing profile, response-time commitment, operating manuals, and documented case studies. | 0–5 |
| Pilot Testing and Scale-Up Capability | 10% | Ability to reproduce refinery feed conditions, evaluate deactivation, compare catalyst formulations, and predict commercial performance. | Pilot testing should control key variables such as temperature, pressure, hydrogen-to-oil ratio, liquid hourly space velocity, catalyst-to-oil ratio, and feed contaminants. | Pilot-unit specifications, test protocols, raw-data examples, repeatability results, and scale-up methodology. | 0–5 |
| Supply Capacity and Delivery Reliability | 10% | Annual capacity, production flexibility, raw-material security, inventory policy, packaging capability, export experience, and contingency planning. | Capacity should be sufficient for the required campaign volume, with realistic lead times and a documented plan for quality-controlled capacity expansion or emergency supply. | Capacity statement, historical on-time-delivery data, production schedule, logistics procedure, and business-continuity plan. | 0–5 |
| Regulatory, Safety, and Environmental Compliance | 5% | Compliance with applicable chemical, transport, workplace-safety, waste-management, and environmental requirements in both China and the destination market. | Safety data sheets should follow the applicable GHS-based format, and hazardous materials should be classified, packaged, labeled, and transported according to destination-country rules. | Safety Data Sheets, transport classifications, environmental permits, emissions records, REACH or other destination-market documentation where applicable. | 0–5 |
| Lifecycle Cost and Value | 5% | Total cost of ownership, including purchase price, loading volume, cycle length, regeneration or replacement frequency, energy impact, yield improvement, and spent-catalyst handling. | The lowest purchase price is not necessarily the lowest operating cost; evaluation should use cost per ton of feed or cost per ton of saleable product over the full catalyst cycle. | Comparable commercial quotations, cycle-length assumptions, performance guarantees, logistics costs, and spent-catalyst treatment terms. | 0–5 |
