Abstract
The possibilities of mechanochemistry in processing of renewable lignocellulose raw material into solid kinds of biofuel are demonstrated in this work. A review of lignocellulose raw materials promising for our country is presented. These raw materials include wastes from agriculture and forestry, and the biomass of rapidly growing plants. The physicochemical properties of lignocellulose materials with different delignification degrees were modeled with the help of the artificial mixtures of plant raw material with purified cellulose and lignin. The data illustrating the effect of disperse state and lignin content on the reactivity of the material in subsequent combustion are presented. The tests at the combustion bench with the thermal power up to 5 MW allowed determining the optimal combustion parameters for the obtained biofuel in the autothermal mode.
Highlights
Much attention in the world is paid to the shift from mineral to renewable energy sources
Significant progress has been made in the industrial production of woodbased solid biofuels and in the consumption of new kinds of biomass as raw materials [2,3]
Studies are aimed at optimization of the combustion of artificial mixtures, including lignin from black liquor and various kinds of coal [6]
Summary
Much attention in the world is paid to the shift from mineral to renewable energy sources. Significant progress has been made in the industrial production of woodbased solid biofuels and in the consumption of new kinds of biomass as raw materials [2,3]. The sources of biomasses suitable for biorefinary and biofuel production are under investigation in many developing regions of the world [4]. These sources include the biomass of plants growing in a specific region, and agricultural wastes [5]. Studies are aimed at optimization of the combustion of artificial mixtures, including lignin from black liquor and various kinds of coal [6]
