Activated carbon is used as a filter medium during the water treatment process. Due to the high porosity of activated carbon, it is used to adsorb both organic and inorganic foulants that are found in the raw carbon certainly does most of the heavy lifting within the water treatment process.
For carbon that comes into the carbon regeneration kiln dry, either a small amount of water or steam needs to be introduced into the heat tube to create the steam rich environment needed to regenerate the activated carbon. The steam also acts as a barrier for oxygen infiltration into the heat tube.
Activated carbon is the most popular waste water treatment sorbent, yet its application is limited and the cost of regeneration is relatively high. Results presented in this study show that vacuum regeneration of activated carbon is promising. Potentially, vacuum regeneration of activated carbon could be achieved in place.

Carbon regeneration kiln discharge end CARBON REGENERATION PROCESS Activated carbon adsorbs neutral species. These species can be of organic and inorganic nature. The presence of these species on the internal surface arbon will reduce the ability of activated carbon to adsorb desirable
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.
''s carbon regeneration systems utilize thermal regeneration technology. Some industries call the product "AC" for activated carbon. The process uses an indirect fired kiln to heat the activated carbon to 700°C, driving off the organic and inorganic contaminants. The system uses a recycle duct to improve energy efficiency.
Activated carbon, also called activated charcoal, is a form of carbon processed to have small, lowvolume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes substituted with active.. Due to its high degree of microporosity, one gram of activated carbon has a surface area in excess of 3,000 m 2 (32,000 sq ft) as determined by gas adsorption.
This final process allows the carbon to recover its structural integrity prior to being discharged from the carbon regeneration kiln. In doing so, the regenerated carbon reduces its exposure to thermal shock if it discharges into a quench tank and at the same time, reduces the possibility of fracturing and creating carbon .
chu66 Activated Carbon Regeneration Kiln for gold extraction Activated Carbon Regeneration Kiln is suitable for allsliming cyanidationzinc method in the process of gold, also can be used in other industries roasting or drying. 2.
A simple, economical process is disclosed for regenerating granular activated carbon, using a combination of alcohol, alkali, and oxidant, preferably ethanol, sodium hydroxide, and hydrogen peroxide. The regeneration process employs inexpensive compounds, is wellsuited to be implemented onsite, and does not require spent carbon to be transported to a specialized facility for regeneration.

QSY Rotary Kiln is mainly used for activated carbon regeneration in Gold CIP Production Line. After gold loaded carbon desorption, it is washed by dilute sulphuric acid or nitric acid to remove the accumulation such as calcium carbonate, after several working cycle, the carbon must be thermodynamic activation to regain the activity.
Nutec Bickley rotary kilns for carbon regeneration are furnished with a complete control system which will permit kiln operators to regulate all of the kiln parameters, such as carbon feed rate, process temperatures, steam flows, kiln pressure etc. These kilns can be monitored remotely and Industry trend monitoring can be incorporated.
Activated carbons are used in hundreds of different purification applications. In many cases, when the carbon is spent or the treatment objective is no longer being achieved, the spent carbons can be recycled via thermal reactivation, a process we refer to as RegenSys®. The main benefits of carbon regeneration are as follows:
The Carbon is then outputted from the Kiln at 250°C through the discharge nozzle and onto the vibratory screen. As the injection of water in the furnace zone vaporises and forms the inert atmosphere under which regeneration takes place; an effectively dry carbon screen allows granular flow immediately on kiln .
CARBON REGENERATION PROCESS. Activated carbon absorbs neutral species. These species can be of organic and inorganic nature. The presence of these species in the internal surface and in the pores of the activated carbon will reduce the ability of activated carbon to absorb desirable species, in this case gold (in the calcium gold cyanide ion pair).
This invention relates to a regeneration process and facilities of spent activated carbons, the process being characterized by pyrolyzing in the low temperature range of between 200 °C and 800 °C, the facilities by comprising 1) a feeding section; 2) a reaction section in which pollutants attached to the spent activated carbons are removed by heat treatment, and which comprises a rotary kiln ...
