Abstract
Thermal modification of lignocellulosic particles to obtain a solid biofuels with improved properties. The aim of the study was to investigate the effect of the thermal pretreatment of lignocellulosic raw materials on the properties of solid biofuels. The preliminary studies included mustard straw, hemp straw, grass stalks, tobacco stalks, sunflower hulls, miscanthus straw, rape straw, cereal straw, Virginia mallow straw and rape seeds. Torrefaction was carried out in nitrogen atmosphere at 220°C for 30 minutes. It was specified the weight loss of the torrefied samples. In the raw and torrefied materials the ash content, elemental analysis, calorific value and water absorption were determined. It was found that the thermal treatment of the tested lignocellulosic materials is able to provide solid biofuels with improved properties - better calorific value and hydrophobicity. The obtained results indicate for further research needs, particularly in terms of conditions of the torrefaction process. Keywords:
