Powdered Activated Carbon Manufacturing

Powder Activated Carbon manufacturing may be essentially classified into two types:

Activated carbon that has been chemically powdered Activated carbon powder It has a black powder appearance, is odorless and tasteless, and does not dissolve in common solvents. High-grade wood chips and husks are employed as raw materials, and zinc chloride and phosphoric acid are used as activators. They've been carbonized, activated, and purified. The end product has a high adsorption capacity and a low impurity level. It may be used to purify the decolorized phase of sugars such as glucose, sucrose, and maltose, as well as to remove, purify, and purify macromolecular colors in citric acid, cystine, oil, and chemical products. When water is filtered, its quality is lost.

This topic will be expanded upon to include test techniques to assist water plant staff in selecting the appropriate activated carbon for a certain application as well as monitoring the efficacy and life cycle of the carbon until its final disposal.

The second kind

Powdered activated carbon was used in the physical approach. Properties of powdered activated carbon: high-quality shell and Wood Activated Carbon as raw materials; steam activation; refined treatment; crushing; the appearance of black fine powder; non-toxic, odorless; large specific surface area; and strong adsorption capacity. Use of powdered activated carbon: This product is appropriate for the decolorization, impurity removal, and enhancement of pharmaceuticals, food additives, monosodium glutamate, chemicals, drinks, and so on, as well as the treatment of water. It has a high decolorization strength and a quick filtering speed, making it ideal for decolorizing and purifying medications, insecticides, and Chinese and Western medicines.

Let us discuss the powdered activated carbon regeneration technique, which is divided into three stages: hydrochloric acid treatment, vacuum pumping filtration, and activation and regeneration treatment. It is distinguished by the addition of 200–300 kg of 0.15 N to an acid-resistant pool containing 100 kg of waste powdered activated carbon. Heat the hydrochloric acid to 100 °C for 3 hours, then add 500 g of water, let it stand, remove the top layer of water, and repeat the layering till the carbon slurry achieves PH4. Utilize the PH4 carbon slurry. The vacuum pump is used to filter the carbon cake, which is then dried to a water content of about 30% before being crushed into carbon powder. The carbon powder is then deposited in a refractory crucible, which is then suspended in a furnace, and the vacuum is suspended. The heat preservation furnace cover is installed on the bottom of the furnace, and the flue gas produced by burning coal in the coal burning chamber is heated to 700–900 °C for about 5 hours. The furnace lid is raised after 5 to 20 hours of heat preservation, and the fire-resistant concrete is pulled out of the furnace. Allow it to cool naturally before removing the charcoal powder.
