The raw materials for activated carbon are derived from plant biomass, petrochemicals or coal. To start, the materials are converted to a raw activated carbon by the use of dehydrogenation agents or dry distillation. This is then fully activated by partial oxidation using a special activation reagent at 700 to 1000 °C. The resulting activated carbon can then be impregnated with chemicals that improve its performance, e.g. so that it captures pollutants or contaminants even more effectively.
At IBU-tec, we produce activated carbon from both organic and synthetic sources by steam activation in rotary kilns. We can leverage your project, having built a substantial knowledge base over the course of numerous projects both in production and development.
A good example being a project to expand the applications of activated carbon as a filter medium, where we developed bead-shaped activated carbon with a variety of special surface treatments. Easy handling and filtering were the most important goals: conventional powdery material does not meet these criteria well, so we developed a special form of activated carbon as spherical beads. The beads have an enormous interior surface area and are completely dust-free, maintaining high mechanical strength. This results in outstanding performance as a gas filter, with equally excellent handling characteristics and profitability.
