– computer control system for adjusting the rate of material feeding and mixing
– possibility to connect the supply of neutral gases through the process
– possibility to connect two monitors for operating and displaying of process parameters
– possibility to connect the control unit to laboratory/institutional computer network, monitor and operate the process parameters though intranet/internet remote computer access
Operation
Solution for MAX-phase for etching is poured into reactor and hermetically closed by a cover, which enables a controlled and safe removal of hydrogen.
MAX-phase feeding is done at a constant rate. To prevent deposition of material, the solution is constantly mixed. Chemical reaction of MAX-phase etching is exothermic. A water-cooled shell and feeder for material supply are designed for the temperature control.
MAX-phase etching is done following, for example, the reaction:
Ti3AlC2 + 3HF + 2H2O = AlF3 + 5/2H2 + Ti3C2(ОН)2
Hydrogen that is formed during the etching process flows into the discharge system for further utilization or is discharged. After etching, the solution is discharged for product purification from reaction products and other impurities.

FAQ
Activated carbon is referred to porous carbon that is produced through a prosity-development process called activation. The activation process involves high temperature treating of already pyrolyzed carbon (often referred as char) using activating agents such as carbon dioxide, steam, potassium hydroxide, etc. Activated carbon has great adsorption capabilities which is why it is used in liquid or vapor phase filtration media. Activated carbon has surface area greater than 1,000 square meters per gram.
Adsorption is the process by which liquid or gaseous molecules gets attracted to the inner pore walls of activated carbon. Adsorption is different from absorption. In absorption, molecules are taken up by the volume, not by the surface (as in adsorption).
The use of activated carbon extends back into history. Indians used charcoal for drinking water filtration, and carbonized wood was used as a medical adsorbent by the Egyptians as early as 1500 B.C. Activated carbon was first manufactured industrially in the first part of the twentieth century, when it was used in sugar refining. Powdered activated carbon was first produced commercially in Europe in the early 19th century, using wood as a raw material.
In general, activated carbon can be produced from a variety of carbonaceous material. The three most common raw materials for activated carbon are wood, coal and coconut shell.
Activated carbon made from wood is called activated charcoal.
Decolorization of sugar and sweeteners, drinking water treatment, gold recovery, production of pharmaceuticals and fine chemicals, catalytic processes, off gas treatment of waste incinerators, automotive vapor filters, and color/odor correction in wines and fruit juices.
As per IUPAC standards, pores are usually categorized as follows:
Micropores: referred to pores less than 2 nm; Mesopores: referred to pores between 2 and 50 nm; Macropores: referred to pores greater than 50 nm
Coconut shell activated carbon has a large quantity of micropores making it superior to coal grades for the removal of smaller organic compounds, low boiling point chemicals with strong odors and dechlorination applications. Coconut shell activated carbon is a material of choice for manufacturers of water filters and respirators.
Coal based and wood based carbons contain meso and macropores and thus are used in applications such as dye removal where larger color compounds can be successfully adsorbed.
Iodine number is a commonly used parameter used to characterize activated carbon performance. It is a measure of activity level (higher number indicates higher degree of activation), often reported in mg/g.
It is a measure of the activated carbon’s resistance to attrition. It is an important indicator of activated carbons ability to maintain its physical integrity and withstand frictional forces imposed by backwashing, etc. We follow ASTM standard 3802 to determine hardness number.
CTC is most widely used method is to measure the carbons capacity to adsorb carbon tetrachloride and express this as a weight/weight %. This is determined by flowing CTC laden air through a sample of carbon of known weight, under standard conditions, until constant weight is achieved. The weight of CTC adsorbed is referred to as the carbons % CTC activity. We follow ASTM standard 3467 to CTC activity.
The internal surface area of a carbon is usually determined by the BET (Brunauer, Emmett and Teller) method.

Reactivated carbon
Reactivated carbon is spent carbon that is recycled by treating it at elevated temperature in oxidizing atmosphere.
Reactivated carbon can be used in place of new virgin carbon for aqueous and vapor applications to remove organics. Reactivation process destroys organic compounds that had been adsorbed onto the carbon and thereby increases the surface area and pore volume of the spent carbon.
Reactivated carbons can be used in all applications where virgin carbons have been traditionally used and are suitable for use in treatment of potable water, process water, wastewater, groundwater remediation and other applications.
We offer several grades of coal, wood and coconut shell based reactivated carbon depending on mesh sizes and iodine number:

Filters
We develop and sell carbon air and liquid filters. The filters can be manufactured to OEM specifications in a wide variety of shapes and sizes. We do not have minimum order requirements for filters and thus no order is too small for us. We have the ability to quickly respond to your filter needs and to rapidly develop R&D prototypes for testing. Selected activated carbon or specialty carbon materials will be used in our filters depending on your requirement. Our custom made filters can be fabricated for trapping chlorine, ozone, hydrogen sulfide, chloroform, benzene, etc. from liquid or solid streams.
Carbon rolls
Activated carbon is one of the most effective and commonly used sorbents for removal of a wide range of odors and gases found in the commercial, institutional, industrial and residential settings. Our carbon rolls are made from impregnation of fine activated carbon into non-woven polyester and are available in a variety of sizes (width and thickness). The optimum loading of carbon offers low resistance to air flow required for adequate performance.
Carbon roll is ideal for HVAC (heating, ventilation, and air conditioning) units, such as air cleaners, air purifiers, ductless hoods and over the range ovens. Large volume of pores in our carbon rolls allows efficient and safe removal of smoke, pet, cooking and chemical odors. We have the experience and expertise to work with original equipment manufacturers to design and develop superior carbon rolls that is made specifically for that customer’s application.
We have the capability to make specially designed carbon rolls for you.
Food packaging
Fruits and vegetables produce ethylene gas that causes it to ripen. Ethylene changes the color of green tomato from pink to red and a rose bud or carnation to open to a beautiful flower. The rate of ripening depends on the amount of ethylene gas. Our sachet contains palladium-impregnated activated carbon and is prepared to take care of above such problems and keep your products fresh and avoids ripening them. Off the shelf activated carbon has lower affinity to adsorption of ethylene. The adsorption of ethylene is enhanced in our carbons because of impregnation of palladium (Pd) in our activated carbon, which acts as a catalyst and allows stronger adsorption of ethylene.
Use of our sachets helps in lower food costs and wastage, which is achieved by extending the life of your fresh produce by 3-4 times longer. It also helps in removal of moisture. The sachet is easier to install. It can be used in refrigerator, food storage, food packaging, and related applications.
VOC removal
The use of activated carbon is one of the leading technologies for the removal of volatile organic compounds (VOC’s) from commercial and industrial air discharges. ActiveU can be used for the capture of VOC’s in many industries. These include, but not limited to, petrochemical, pharmaceutical, metal processing, pulp and paper, and food processing. Further downstream applications include dry cleaning, paint spray booths, plating, HVAC (heating, ventilation, and air conditioning) systems, solvent recovery systems, groundwater remediation, and indoor home air purification units.
