AmberLyst 131B

Summary

Product identification

• Product Name: AmberLyst™ 131B Polymeric Catalyst
• Product Type: Industrial-grade, Strongly Acidic Catalyst
• Description: A strongly acidic, gel, uniform particle size, polymeric catalyst partially loaded with a promoter, highly active for condensation reactions. Especially used in the condensation of phenol with acetone to produce Bisphenol-A (BPA). The uniform particle size allows for reduced reactor pressure drop and higher productivity compared to conventional polymeric catalysts.

Applications

• Condensation (Bisphenol-A)

Suggested Operating Conditions

• Maximum Operating Temperature: 130°C (265°F)
• Bed Depth, min.: 600 mm (2.0 ft)
• Pressure Drop, max.: 1 bar (15 psig) across the bed
• Flowrates:
  • Linear Hourly Space Velocity (LHSV): 0.5 – 5 h⁻¹
• Backwash: See Figure 1 in the original document.

Hydraulic Characteristics

• Estimated bed expansion as a function of backwash flowrate and temperature is shown in Figure 1 (Temperature: 10 – 90°C).
• Estimated pressure drop as a function of service flowrate and temperature is shown in Figure 2 (Temperature: 10 – 90°C). These expectations are valid at the start of the service run with clean water.
