Catalyst with Coarse beads
SEPLITE® CT502 Catalyst Resin
Product Overview
SEPLITE® CT502 is a large-bead polymeric catalyst manufactured through a specialized one-step polymerization process of styrene and divinylbenzene followed by sulfonation. Designed for catalytic reaction towers and reactive distillation systems, it combines catalytic activity with separation functions, helping improve process efficiency while reducing equipment investment.
Featuring uniform particle size, ultra-large pore structure, high exchange capacity, and excellent mechanical strength, SEPLITE® CT502 delivers superior mass transfer performance, high catalytic activity, and long service life under demanding industrial operating conditions.
Key Features
- Large bead design (Φ5–8 mm) for low pressure drop
- Uniform particle size and minimal material resistance
- Ultra-large pore structure for enhanced mass transfer
- High exchange capacity and catalytic efficiency
- Excellent mechanical strength and pressure resistance
- High porosity and long catalyst service life
- Non-corrosive and low fouling characteristics
- Suitable for reactive distillation applications
Applications
SEPLITE® CT502 is widely used in catalytic reaction and reactive distillation processes, including:
- Isobutene hydration to produce tert-butyl alcohol (TBA)
- Propylene hydration
- Butylene hydration
- Methyl synthesis processes
- Isobutene production through tert-butanol dehydration
- Other acid-catalyzed petrochemical reactions
Product Type
- Strong acid polymeric catalyst
- Large bead sulfonated styrene-divinylbenzene catalyst
Advantages in Reactive Distillation
Compared with conventional catalyst packing units and columnar resin catalysts, SEPLITE® CT502 offers:
- Simultaneous catalytic reaction and distillation
- Reduced equipment investment
- Easier operation and maintenance
- Higher mechanical strength
- Better temperature resistance
- Improved catalytic activity
- Resistance to deformation and agglomeration
These characteristics make it particularly suitable for industrial reactive distillation systems operating under challenging process conditions.
Storage & Handling
- Store in sealed containers or bags
- Keep in a dry environment with temperatures above 0°C
- Protect from direct sunlight and moisture exposure
Safety Precautions
- Do not mix with strong oxidizing agents
- In case of eye contact, rinse immediately with plenty of water and seek medical advice
- Dispose of materials according to local regulations
- Dry polymer may expand and generate heat when wetted
- Spilled material may create slippery surfaces
