Zero Thermal Desorption
Chemical conversion inside the pores prevents trapped formaldehyde from escaping when room temperatures rise.
01 / 05 · Studio PackshotZero-Desorption Chemisorption Charcoal
botouseneco Amino-Acid Modified Activated Carbon Packs upgrade traditional physical charcoal into an irreversible chemisorption medium. Using high-iodine (≥1050 mg/g) coconut-shell columnar carbon impregnated with 8% amino-acid salts, it physically captures and chemically decomposes formaldehyde inside drawers, wardrobes, and cars without secondary thermal desorption.

01Overview
True chemisorption carbon packs that never release trapped formaldehyde back into hot rooms.
Ordinary bamboo or coal activated carbon relies purely on weak van der Waals physical adsorption: because formaldehyde has a low boiling point (-19.5°C) and high polarity, standard charcoal saturates within 7–15 days and releases trapped HCHO back into the room as soon as summer temperatures rise above 28°C. botouseneco Amino-Acid Modified Activated Carbon Packs eliminates this industry pain point. We select high-iodine (≥1050 mg/g) virgin coconut-shell microporous carbon and vacuum-impregnate its internal pore walls with active amino-acid salts—turning every carbon pellet into a solid-phase chemical reactor.
Chemical conversion inside the pores prevents trapped formaldehyde from escaping when room temperatures rise.
Virgin microporous coconut-shell carbon provides 3x the micropore volume of cheap coal or bamboo charcoal.
Vacuum-impregnated food-grade amino salts multiply formaldehyde breakthrough capacity by over 600%.
Available as retail-ready linen/SMS pouches (50g–500g) or 25kg bulk bags for filter manufacturers.
Reaction mechanism
Developed pore networks (0.6–2.0 nm) capture airborne HCHO and benzene homologues via capillary condensation. Inside the pore channels, grafted primary amine (-NH₂) groups immediately convert adsorbed formaldehyde into non-volatile urotropine/imine derivatives, regenerating physical pore capacity and preventing thermal desorption.

03Application
Ideal for dark, unventilated drawers where sprays and light cannot circulate.
Place 100g pouches at the rear of dresser drawers, filing cabinets, and storage beds. Because the formaldehyde is chemically converted inside the pellets, sun-drying is not required to prevent HCHO rebound.
Record initial HCHO/TVOC readings (mg/m³), room temperature (°C), relative humidity (% RH), and closure window (1h vs. 12h).
Identify whether off-gassing stems from urea-formaldehyde MDF/particleboard, phenolic plywood, solvent lacquers, or textile backings.
Calculate total surface area (m²) of panels, walls, and ceilings to determine exact liquid volume (ml/m²) and nozzle gauge (0.5mm–1.0mm).
Confirm sample evaluation batch, TDS/MSDS export documentation, and commercial drum sizing (1L / 5L / 20L / 25L / 200L).

08Questions
Regular bamboo charcoal has large macropores poorly suited for tiny 0.37nm HCHO molecules and quickly re-emits gas when warm. Amino-Acid Modified Activated Carbon Packs uses ≥1050 mg/g microporous coconut carbon chemically impregnated with amino acids that permanently convert HCHO into solid imine salts.
