Solvent Recovery Activated Carbon
Recovering toluene, acetone or gasoline vapor? CTC and ignition point matter.
Selection Logic
| Scenario | Requirement | Recommended | Key Spec |
|---|---|---|---|
| Organic solvent recovery (toluene / acetone / ethyl acetate) | Large capacity, regenerable | Extruded recovery carbon | CTC 30–120% |
| Gasoline-vapor recovery (VRU) | High-temperature, safe | High ignition-point extruded carbon | Ignition ≥350°C |
| Printing / coating off-gas | Low resistance, smooth flow | 0.9–8mm extruded carbon | Diameter by duty |
Scenario Guide
Organic Solvent Recovery → Extruded Carbon
Filled in fixed-bed adsorbers, CTC value determines adsorption capacity; 30–120% is graded by solvent type. After saturation, the solvent is recovered by desorption and the carbon regenerated for reuse.
Oil-Vapor Recovery → High Ignition-Point Carbon
Gasoline-vapor recovery regenerates at high temperature, so the ignition point must be ≥350°C for safety.
Key Parameters
◆
CTC
Carbon tetrachloride value — measures organic-solvent adsorption capacity; 30–120% graded by solvent.
◆
Ignition Point
Safety threshold for high-temperature regeneration; ≥350°C.
◆
Diameter
0.9–8mm extruded; determines bed resistance and gas-flow smoothness.
◆
Hardness
Durability in fixed beds; ≥90%.

FAQ
Why is the ignition point important for solvent recovery carbon?
Solvent and gasoline-vapour recovery regenerates at high temperature, so the ignition point must be ≥350°C to operate safely under desorption conditions.
What CTC value should I choose?
CTC 30–120% is graded by solvent type — the more demanding the solvent load, the higher the CTC grade you specify.
How many times can the carbon be regenerated?
Regenerable extruded carbon recovers solvent on desorption and is reused over many cycles; lifetime depends on solvent purity and operating care.
Why extruded (pellet) form for solvent recovery?
Extruded carbon (0.9–8 mm) gives low bed resistance and smooth gas flow in fixed-bed adsorbers, and its strength survives repeated regeneration.
