Adsorb Technologies (Pty) Ltd Information

As the name suggests Adsorb specialises in carbon adsorption solutions and technologies. Solutions include but are not limited to fixed-bed adsorption, pulse-bed adsorption, thermal reactivation and pyrolysis. In addition it has three proprietary technologies that it sells and supports. These are a pulse-bed adsorption system, a fluid-bed reactivation system and a flash-pyrolysis system. Carbon and specifically activated carbon is both an underestimated and underutilised purification technology. Unfortunately, it is negatively tarnished by its colour, often perceived to be a dirty process. If anything it is an environmentally friendly technology, especially when using biomass based carbons e.g. coconut shell and wood. What is required is better engineering to ensure that carbon is contained and not allowed to “dirty” its name. The age-old process of pyrolysis (charcoaling for laymen) is receiving renewed interest. The reason for this is its carbon negative potential, capable of limiting climate change. Its link to activated carbon is twofold: i) char is a potential raw material for the manufacture of activated carbon and ii) the thermo-chemical reactions involved are similar to those used in thermal regeneration of activated carbon. In other words pyrolysis and activated carbon are complimentary.
