Effect of Raw Materials on Properties of Activated Carbons

Activated carbon can be produced from a large variety of raw materials, basically by two methods, physical and chemical activation or a combination of both. The adsorption properties of activated carbon vary with the feed materials used and the way of activation. Production cost may be lowered by choosing a cheap raw material and performing a suitable production process. Agricultural and forestry residues, or generally, biomass residue wastes could be used as suitable raw materials for the production of activated carbon. In the present work, different agricultural residues such as hard shells of apricot stones, almond, walnut and hazelnut shells, rice hulls and residues of liquorices were used as precursors. The activation was performed using phosphoric acid under the same conditions. The results showed that at the selected experimental conditions, the type of biomass as well as the final activation temperature, heating rate and impregnation rate of the chemical agent had the greatest influence on the quality of activated carbon. The quality of activated carbon was evaluated in terms of the iodine number reflecting the surface area. According to the results, activated carbon from the hard shells of apricot stones had the best adsorption properties and the largest surface area.     

不同原料制备钛酸铝陶瓷性能比较

采用2种原料分别为高铝矾土和氧化钛、工业氧化铝和氧化钛。粉料经过预烧之后经成形、烧结制备陶瓷。为了比较2种制品。分别对其进行了抗压强度、抗折强度、热膨胀系数、热震稳定性测试及微观形貌观察。结果表明．采用前者为原料制备的陶瓷性能可以与后者相媲美。同时由于高铝矾土价格便宜．因此更适用于工业生产的需要。     

Use of Unconventional Raw Materials with Regard to Their Redox Properties

The possibility of using nontraditional materials allowing for their redox parameters in the production of container glass to replace sand and soda is investigated. It is established that the color and quality of glass can be predicted based on integrated use of such parameters as the chemical oxygen minimum and the redox potential of a batch.
