Why Powdered Activated Carbon Sometimes Causes Slow Filtration in Decolorization Processes – and How to Improve It
Powdered activated carbon is widely used for liquid decolorization, but some processes experience slow filtration after carbon treatment. This article explains the main reasons behind filtration problems, including particle size distribution, fine powder content, carbon dosage, solution properties, and filtration conditions, while offering practical ways to improve overall process efficiency.
How Rising Phosphoric Acid Prices Affect Wood-Based Powdered Activated Carbon
Rising phosphoric acid prices are increasing cost pressure on wood-based powdered activated carbon, especially for products produced through phosphoric acid activation. This article explains how raw-material market changes can affect activated carbon pricing, quotation validity, supply planning, and procurement decisions for decolorization and liquid purification applications.
Porous Carbon for Energy Storage: Why Pore Structure Matters
Porous carbon materials are gaining attention in energy storage applications because their pore structure, surface area, conductivity, and stability can influence ion transport and charge storage. From supercapacitors to battery-related materials, advanced porous carbon requires precise structural design, stable production, and application-oriented performance.
HANYAN Launches Thousand-Ton Energy Storage Porous Carbon Production Line
HANYAN has officially launched its thousand-ton-scale energy storage porous carbon production line, marking a new step in the industrialization of high-end porous carbon materials.

Why Activated Carbon Selection Should Be Based on Process Conditions, Not Just Datasheet Values
Activated carbon selection should not rely on datasheet values alone. Real performance depends on process conditions such as VOC composition, temperature, airflow, humidity, and system design, all of which can significantly affect adsorption behavior and service life.
Activated Carbon Regeneration vs Replacement: How Industrial Users Should Evaluate Cost, Risk, and Performance
Activated carbon regeneration and replacement each have advantages depending on the application. A practical decision should consider cost, performance retention, operational risk, and system stability rather than media price alone.
Why Activated Carbon Buyers Should Not Wait Until Stock Runs Low to Reorder
In activated carbon procurement, waiting until inventory is almost depleted may seem efficient, but it often increases supply risk. This article explains why reorder timing matters and how buyers can plan earlier to reduce delays, cost pressure, and operational disruption.
How Activated Carbon Manufacturers and Users Can Prepare for Supply Disruptions in a 2026 Volatile Global Market
In the activated carbon industry, supply risk is no longer just about price. Raw material tightness, longer lead times, and shipping disruption can all affect project schedules and operating continuity. This article explains what activated carbon manufacturers and users should do in advance to reduce supply risk and protect project progress.
Why Lab Data Alone Cannot Define Activated Carbon Performance
Laboratory test data such as iodine value, CTC, and surface area are important – but they do not fully determine activated carbon performance in real industrial systems. True performance depends on operating conditions, flow dynamics, and application-specific priorities.
