A study on the preparation of pitchbased highstrength columnar activated carbon and mechanism of phenol adsorption from aqueous solution† Peng Yao, Jianmeng Cen, Mengxiang Fang, * Tao Wang and Qinhui Wang Coal tar pitch was ground into powder and hydroformed with high pressure. After preoxidation, the pitch was activated byCO 2 at ...
A coal tar pitch with QI was used to prepare MCMBs. Some properties of the coal tar pitch are summarized in Table 1. During the preparation of MCMBs, an additive of alumina powders (commercial product, analytical reagent) with size of less than 2 μm was added into the parent pitch. The morphology of the alumina powder is shown in Fig. 1.

Coal tar is derived from coal. It is a byproduct of the production of coke, a solid fuel that contains mostly carbon, and coal gas. Coal tar is used primarily for the production of refined chemicals and coaltar products, such as creosote and coaltar pitch. Certain preparations of coal tar have long been used to treat various skin conditions ...
Difference Between Coal Tar and Asphalt Since the Industrial revolution, bituminous materials are very much preferred in building and road constructions. These materials are composed of highly molecular weight hydrocarbons, and soluble in carbon disulfide. There are many grades of bitumen, each of which exhibits different characteristics. The performance of each grade of bitumen depends ...
