Carbon Regeneration - Mineral Processing Metallurgy
Oct 23, 2016 Consequently, the performance of the activated carbon decreases unless it is regenerated. Regeneration generally consists primarily of thermal activation in a rotary kiln at around 650 C in steam to remove organic debris. Thennal activation is preceded or followed by exposure to hydrochloric acid to remove inorganic precipitates such as carbonates.
MoreCarbon Regeneration - Ansac
Activated carbon must be reactivated or regenerated back to as close to as new condition as possible for the adsorbtion process to remain efficient. In practical terms, three key factors are necessary to reactivate or regenerate carbon: − Temperature − High Steam Partial Pressure − Residence Time. Carbon at 650°C exposed to air will combust.
