Start with an analysis of feedstock characteristics and production targets. Key selection factors include: 

• Feed composition (naphtha, propane, butane ranges).
• Target products (propylene, ethylene, BTX aromatics). 
• Operating temperatures and pressures 
• Desired cycle lengths. 
• Existing equipment configurations.
   

Honeywell UOP catalyst datasheets provide technical specifications and performance data. Our technical team can help evaluate options based on your specific requirements; pilot testing can help validate performance before full-scale deployment.

To assess catalyst performance, we recommend tracking these core indicators: 

• Yield percentages for target products.
• Conversion rates across operating cycles. 
• Temperature differentials (delta-T).
• Pressure drop trends. 
• Product quality specifications. 
• Cycle length duration.  

Industry best practice involves monitoring trending data rather than single-point measurements. Gradual changes in yields or conversion rates can signal catalyst deactivation. Temperature and pressure patterns can help inform maintenance and regeneration planning.

Honeywell UOP's petrochemical catalysts are designed for feedstock flexibility across major process applications.

• Methanol-to-Olefins (MTO) catalysts can convert methanol from natural gas, coal or renewable sources into ethylene and propylene.
• Oleflex catalysts for propane dehydrogenation can switch between propane and methanol feeds based on feedstock availability.
• Parex adsorbents can accommodate reformate composition variations with higher throughput.
• Tatoray catalysts can handle variable aromatic feeds while helping maintain activity and selectivity.
• Isomar catalysts can efficiently process mixed-xylene streams across different feed compositions.

For significant feedstock changes, Honeywell technical support teams can assess catalyst compatibility and expected performance under new operating conditions.
