P-100 2mm Coal Columnar Carbon for Sulfide Removal and Air Purification

The P-100 utilizes reduced 2.0mm diameter to maximize surface area-to-volume ratio for applications demanding rapid adsorption kinetics or compact bed design—ideal for sulfide removal in confined spaces and high-efficiency HVAC filtration.

Product Overview

The 2.0mm extruded diameter of P-100 delivers 60% greater external surface area than standard 4mm carbon, accelerating mass transfer for reactive gas removal and enabling shallow-bed designs for space-constrained installations.

Sulfide Removal Application:

When paired with proper impregnation (SRC-A/SRC-E type), the fine particle size accelerates H₂S and mercaptan removal in biogas, landfill gas, and wastewater treatment applications where rapid reaction is essential.

Technical Advantages

High Mechanical Strength & Cost-Effective Purification

Our coal-based activated carbon is manufactured from premium bituminous coal through steam activation, delivering exceptional hardness (>90%) and abrasion resistance for demanding industrial applications.

With iodine adsorption values exceeding 900-1000 mg/g and customizable particle sizes (4×6 mesh to 12×40 mesh), it ensures optimal performance in drinking water treatment, wastewater purification, and air filtration systems. The high bulk density (350-550 kg/m³) and superior CTC adsorption (50-90%) make it ideal for VOC removal, solvent recovery, and gas-phase applications.

Available in granular (GAC), powdered (PAC), and columnar forms for maximum operational flexibility.

FAQ

Q1: When should I specify 2mm vs. 4mm columnar carbon?

A: Choose 2mm when: (1) Space constraints require shallow beds, (2) Rapid adsorption kinetics are critical (reactive gases), (3) System design accommodates higher pressure drop, (4) Enhanced impregnant distribution is needed. Standard 4mm suits general applications with lower pressure drop tolerance.

Q2: Does the smaller size affect carbon lifetime?

A: Physical lifetime is comparable; however, 2mm carbon reaches saturation faster due to higher surface exposure—advantageous for rapid contaminant capture but requiring more frequent replacement or regeneration. Design for 20-30% shorter service cycles than 4mm equivalent.

Q3: Can you provide samples before bulk order?

A: Yes, samples can be given to you. Please contact us for details. Once we charge you the sample fee, please rest assured that this will be a refund when you place a formal order.

Q4: What is your minimum order quantity (MOQ)?

A: MOQ depends on product type. Please contact us for detailed information.

Q5: How long is the delivery time?

A: Normally 15-30 working days depending on order quantity and production schedule.

Q6: How to confirm payment?

A: We accept T/T ,L/C, and other payment methods are also acceptable. Please contact us before you make payment through other payment methods. In addition, a deposit of 30-50% is feasible, and the balance shall be paid before shipment.
