Abstract

A series of activated carbons has been prepared by steam pyrolysis of apricot and cherry stones, almond shells, and grape seeds at relatively low temperatures of 600, 650, and 700°C for 1-3 h at each temperature. The adsorption properties of the resulting activated carbons were studied as a function of the treatment temperature, soak time, and nature of the precursor. Activated carbons produced from various agricultural by-products showed different pore size distributions, depending on pyrolysis/activation conditions. Among the activation conditions used in this study, the treatment at 700°C for 2 h produced the highest N2 BET surface area and pore volume obtained from each precursor. The activated carbons were characterized by N2 adsorption, iodine, and methylene blue adsorption from solution. The microstructures of the carbons were examined by optical and scanning electron microscopy. The adsorption characteristics of the activated carbons produced from various agricultural by-products were found to be different and strongly dependent on the composition and structure of the raw materials.
