Abstract: High performance mesoporous granular activated carbon was prepared from drupe stones by activation with phosphoric acid.85% H3PO4 was added to drupe stones,then heated and stirred on time to impregnate the material swelling until viscidity vanished and loose,then carbonized,activated,extracted with water and dried.Effects of temperature and time on impregnation-swelling,carbonization and activation on properties of the product were studied by orthogonal test.Also,comparative tests by different treatment methods on the raw materials were carried out.Property tests of the product show the results of maximum carbon tetrachloride adsorption 160%,decolorization of caramel A 130%,abrasion resistance 94%,total pore volume 1.7 mL/g,proportion of the mesopore 40%-50%.

Key words: activated carbon, gasoline adsorption, decolorization
