DE430031C - Production of a high quality active carbon - Google Patents

Description

Production of a high quality active carbon. To make a high quality active charcoal has been suggested to contain vegetable substances crushed and moist condition, such as B. sawdust, peat, sugar beet pulp, Defecation sludge and coal powder, on their own or in a mixture with or without Addition of slaked lime or acetic acid lime in solution or potato starch o. The like. With the exclusion of air under the simultaneous action of water vapor or Steam and carbonic acid to carbonize the glow product with pure water or Wash out with acid and water and glow the charcoal again in the absence of air. Molasses with slaked lime has also been treated in a similar way for the same purpose. Furthermore, a process is already known to remove sawdust, wood chips and chalk to process in a similar way. At last it has been suggested beer or Reefer warehouses and milk sugar mother liquors or mixtures of these with To char potash by a similar process and to process it on absorbent charcoal. Lactose liquors and storage come because of the intricate texture and therefore high prices for the factory-made production of a high-quality active Coal not considered. On the other hand, tests have shown that the value of the active Coal, "-moose by glowing vegetable products with slaked lime, acetic acid Lime or chalk was collected, a relatively small amount.

The purpose of the present invention is to avoid these abuses. Same consists essentially in the fact that mixtures of molasses with spent grains are present of potash charred by a known process and on high-quality active charcoal are processed.

The molasses contains sugar, which after activating in the club with the vegetable charcoal from the spent grains, it has an excellent decolorizing power owns. As a result, the charcoal obtained has the property of being dye solutions, such as B. Methvlenblau, to decolorize to a greater extent than this by other active ones Coal is the case. This beneficial result is probably extraordinary favorable mixture of vegetable and nitrogenous substances in the presence numerous salts. It is especially worth mentioning that the charring without foaming and proceeds quietly.

Example: Potash solution is added to a molasses-spent grain mixture, dried and annealed in the absence of air. The melt will with diluted acid and water are boiled and the charcoal then possibly 1. again under Annealed air seal.

PATENT APPLICATION: Process for the production of a highly active carbon by charring a mixture of organic substances in the presence of potash, thereby characterized in that a mixture of molasses and spent grains is used here, the charred product washed out in a known manner with dilute acid and is annealed again in the absence of air.
