As a DESOTEC customer, you rarely come in direct contact with the activated carbon itself. It may nevertheless be useful to consult the extended Safety Data Sheets as defined by REACH Regulation (EC) N°1907/2006 for the safe handling of activated carbon. In accordance with this REACH regulation, our extended Safety Data Sheets will contain an Annex with Identified Uses and their corresponding information for safe use (exposure scenarios).
- Consult the activated carbon safety data sheet (SDS)
- Consult the general material safety data sheet (MSDS)
Chemical- and steam-activated carbon
The production processes of activated carbon may be divided into chemical and thermal processes both of which require the use of elevated temperatures.
- Chemical activation is achieved by degradation or dehydration of the raw material structure, which is usually sawdust (wood-based).
- Steam activation can be used to activate almost all raw materials (coal-based, coconut shell-based, wood-based etc.). A variety of methods have been developed, but all of these share the same basic principle of carbonisation and initial oxidation followed by an activation step with steam.
Both manufacturing processes lead to activated carbon products with different physicochemical characteristics of which the substances are defined by their different skeleton densities. Consequently two types of activated carbon have been registered for REACH:
- Activated Carbon - Low Density Skeleton
- REACH Registration No: 01-2119488716-22-0023
- Activated Carbon - High Density Skeleton
- REACH Registration No: 01-2119488894-16-0011
Activated carbon hazards
Wet activated carbon preferentially removes oxygen from the air. In closed or partially closed containers and vessels, oxygen depletion may reach hazardous levels. If it is necessary to enter a vessel containing activated carbon, samples should be taken and certain work procedures followed, including local requirements for potentially low-oxygen spaces.
