Abstract

The physiochemical properties and elemental analysis of agricultural residues (AR), such as pepper stalk, corn cob, corn stalk, tobacco stalk, rice husk, rice straw, barley straw and wheat straw, were investigated to evaluate the potential of the AR as a raw material for the production of agropellets. All ARs were high in holocellulose and lignin contents, and had a broad ash content ranging from 1.67% to 10.87%. In quantitative analysis of the ash, all ARs had high potassium and calcium contents following by magnesium and sodium content. In the elemental analysis, nitrogen contents of all AR were much higher than that of larch, and even exceeded the wood pellet standard (< 0.30%) established by Korea Forest Research Institute. The heating values of the AR also were lower than that of larch. The results suggested that the AR used in this study might be appropriate as raw materials of low-grade pellets for cogeneration or large-scale plants. In addition, the AR outdoor-exposed for 2 and 7 weeks was used to fabricate agropellets. Ash, chlorine and nitrogen contents of the agropellets effectively reduced. The results of this study indicate that AR might be used as a raw material of high-grade pellets if agropellets are fabricated with outdoor-exposed AR or a certain amount of wood sawdust in manufacturing process of pellets.
