Product Overview
PLC-450 is the high-performance variant of our columnar carbon series, delivering elevated CTC activity for applications where adsorption capacity directly impacts operating economics. The 450 CTC rating means the carbon can adsorb 45% of its weight in carbon tetrachloride—a demanding benchmark that indicates extensive micropore development.
This grade is specifically engineered for industrial users who run long cycles between reactivation or replacement. The higher capacity extends service life, reduces downtime, and lowers total cost of ownership even though the initial carbon price is higher than lower-activity alternatives.

Key application areas
- Large-scale solvent recovery — maximizing product recovery per pound of carbon
- Industrial VOC control — compliance with stringent emission regulations
- Gas storage and pipeline applications — odorization and impurity control
- PSA (pressure swing adsorption) systems — hydrogen purification, air separation
- Biogas upgrading — CO₂ and H₂S removal for grid injection
Performance Economics
When evaluating carbon lifecycle costs, consider:
- Higher CTC = longer cycles = fewer changeouts = reduced labor and downtime
- Higher CTC = more contaminant removed per pound = lower net carbon consumption
- Higher CTC = smaller beds possible for equivalent duty = lower capital expenditure
- Columnar Strength: Hard extruded pellets resist breakdown in pneumatic conveying and cyclic pressure operations, maintaining bed permeability
For high-duty gas-phase applications, PLC-450 frequently delivers lower total cost of ownership than cheaper, lower-activity alternatives.
