Activated carbon feedstock
Activated carbon is a form of carbon processed for small, low volume pores that increase the surface area available for adsorption or chemical reactions. Due to its high degree of microporosity, just one gram of activated carbon has a surface area in excess of 500 m2 (approx. 1,600 sq,ft,). An activation level sufficient for useful application may be attained solely from a high surface area; however, further chemical treatment often enhances adsorption properties.
The possibilities are endless. Activated char or carbon is currently applied around the globe for water purification and flue gas cleaning. But it can also be applied as a soil enhancer or fertilizer due to its ability to capture high-value nutrients for long periods. This increases crop yield. The results are significant, particularly on poor soils.
