GPC-P
purestar
GPC-P 4×8 granular activated carbon is produced from select coconut shell raw material via controlled carbonization and high-temperature steam activation. The product achieves a high carbon tetrachloride activity (CTC >80%), indicating superior gas-phase adsorption capacity for VOCs, odors, and low-boiling-point solvents. With ash content controlled below 5% and hardness exceeding 95%, it maintains structural integrity under continuous airflow or reactor conditions.
The optimized pore structure and surface chemistry provide effective anchoring sites for precious metal and base metal catalyst precursors, making GPC-P 4×8 a reliable support medium for hydrogenation, oxidation, and environmental catalysis. Simultaneously, its high micropore volume and low pressure drop characteristics deliver excellent performance in air purification, HVAC odor control, carbon dioxide refining, and solvent vapor recovery applications.

Q: What makes GPC-P 4×8 suitable for catalyst support?
A: GPC-P 4×8's optimized surface chemistry and high purity provide effective anchoring sites for metal precursors, while its >95% hardness maintains structural integrity under reactor conditions. Typical precious metal loadings of 0.5–5% by weight are readily achieved.
Q: What is the difference between GPC-P 4×8 and CFV 4×8?
A: GPC-P 4×8 features higher CTC activity and is optimized for both catalyst support and high-performance air purification including CO₂ refining. CFV 4×8 is positioned for standard HVAC and odor control. Choose GPC-P 4×8 when catalytic functionality, higher adsorption capacity, or gas refining is required.
Q: Can GPC-P 4×8 be used for CO₂ purification?
A: Yes, GPC-P 4×8 effectively removes trace organic impurities and odors from carbon dioxide gas streams, making it suitable for food-grade CO₂ and industrial gas refining applications.
Q: Is GPC-P 4×8 suitable for low-boiling-point solvent recovery?
A: Yes, its high CTC activity and developed pore structure provide effective adsorption capacity for low-boiling-point solvents such as acetone, methanol, and ethanol in vapor recovery units.
Q: Can spent GPC-P 4×8 catalyst carbon be regenerated?
A: Spent catalyst carbon can often be thermally regenerated or processed for precious metal recovery, depending on contamination type and value of supported metals. For air purification applications, thermal regeneration restores adsorption capacity for multiple cycles.
