Description:

OOO «UD Chemie» offers activated carbon companies
OOO «GRYFSKAND» (Poland).

OOO «GRYFSKAND» — company producing active carbon in Hajnowka is one of Europe’s largest manufacturers of activated carbons. Its almost a century of experience producing coal company combines with modern technology and solutions, and the highest quality of customer service.
Active carbons produced by LLC «GRYFSKAND», are delivered to customers around the world. They are widely used in chemical, food and pharmaceutical industries, as well as in water purification.

What is activated carbon?
This coal product with a porous structure and adsorption properties, effectively used in many processes of purification and recovery of substances in liquids and in gases. In addition, it is also used in other chemical processes directly in medicine.
Activated carbons are produced in the company «GRYFSKAND» of:
coal, charcoal or fruit seeds and coconut shell in the high temperature controlled oxidation using steam.
High internal porosity affects the adsorption properties and, depending on the type of raw material and the manufacturing process, the product may have acidic or alkaline properties.
Activated carbon is a reducing agent with catalytic properties.
Depending on the type of raw materials and the technology used activated carbons form a wide range of products, which differ from each other in their properties and application.

Activated carbons based on charcoal from hardwood:
Activated carbon from charcoal obtained in physicochemical activation at pace. 800-1000 ° C. Different specific surface area of ??600-1300 m 2 / g, the total pore volume 1.2 — 3.5 cm3 / g, and an ash content of 3-8%.
They are brought to a liquid or granular state (with a certain class size), with the mission to adsorption of the liquid phase. Refer to the type of alkaline bleaching coals CWZ, which correspond to GOST 6217-74 and 4453-74.
Coal type CWZ recommended for bleaching and cleaning of sugar, protein concentrate, beer, wine, vodka, for refining vegetable and animal fats and oils, paraffin, water treatment and waste water treatment.
Through a process of etching acid turns sour coal types CWH and CWL. Recommended for bleaching and cleaning of glucose, starch syrup, fruit juice, lactic, citric, tartaric acid and glutamic acid, to improve the taste and odor of alcoholic beverages, for bleaching and cleaning of organic and inorganic pharmaceutical preparations for bleaching organic material in the chemical industry and for the application catalysts.

Activated carbons based on bituminous coal:
Granular activated carbons made from coal dust and binders by mixing, extruding pellets, and then drying them, and activating karbonizirovaniya steam at a pace. 850-1000 ° C.
Granular activated carbons different bulk density of 400-520 g/dm3, mechanical strength, 94-99% surface area 700-1500 m2 / g, a total pore volume 0,7-1.3 cm3 / g
Produced in the form of cylindrical pellets of diameter 3.5 mm, 1.5 mm and 1.2 mm, or in irregular grains, for example. 0,2-0.4 mm 0,35-0,75 mm. 0.75-1.5 mm.
Granular activated carbons are of different types and product lines are used in the process of adsorption of the gas and liquid phases.
Coals type WG-12, WD-ekstra, WD-1, NC, AG-5, DT0 used mainly for water and various chemicals in the liquid phase.

Activated carbons such as NG, AG, AHD used for adsorption and recovery of volatile solvents, such as benzene, toluene, benzene, alcohol, carbon disulphide, esters, and also for cleaning of unwanted gases and toxic substances.

On the surface of some activated carbons applied chemicals, thus obtained sorbents become chemisorption and catalytic properties. Some of the manufactured sorbents:
SHD-3, NS — the absorption of acid gases; SO2, HCl, Cl2, NO3, H2S, etc.
AS — designed to absorb ammonia and is used to produce absorbent, as well as industrial adsorbers designed to purify the air from the ammonia vapor.
Actipol 1 — intended for an anti absorbent filter, clean the air of harmful and toxic fumes and gases, for example. cyanogen chloride, hydrogen cyanide, arsine, phosgene, chloropicrin
HGS designed to absorb the mercury vapor and is used in industrial adsorbers designed to purify the air contaminated with mercury.

Active cokes

A separate group of products are active cokes diameter of 5 mm or 9 mm, which are intermediate between carbonizate and activated carbon are different, depending on the range, specific surface area of ??100-350 m2 / g, high stability and high temperature combustion. Designed for cleaning exhaust gases of SO2, NOx, HCl, dioxins, furans, heavy metals.
