Coal Based Granular Activated Carbon For Air Purification

The granular activated carbon is made from coal, which is treated with various chemical agents to create a highly porous material with a large surface area. The resulting material has a network of small pores that adsorb pollutants from the air.

Introduction

In air purification applications, the granular activated carbon is typically packed into a filter bed or canister, through which the contaminated air flows. As the air passes through the filter bed, the activated carbon adsorbs pollutants onto its surface, effectively removing them from the air stream.

Coal-based granular activated carbon is highly effective in air purification due to its high surface area and porosity, which allow it to adsorb a wide range of pollutants from the air. The material is also highly durable and can be used for extended periods before requiring replacement.
