INFLUENCE OF STEAM EXPLOSION ON MATERIAL PROPERTIES UNDER PRESSURE AGGLOMERATION

Abstract

The purpose of the study was to determine the influence of the steam explosion process on the change in properties of the material subjected to this process. Wood chips were used before and after the steam explosion (SE), and pellets made from wood chips subjected to steam explosions (black pellet). The scope of the study included determination of physical and chemical characteristics such as moisture content, combustion heat and calorific value, determination of lignin and hemicellulose,  cellulose and hydrogen, carbon, nitrogen and sulfur content. hemicellulose compounds. After the process biomass, there are still mainly cellulose and lignin compounds that are readily biodegradable. The process results in a slight increase in material humidity and lower calorific value, but further processing in the form of agglomeration results in reversal of these effects.

Keywords: black pellet, steam explosion, wood chips
