Abstract

The main aim of this paper is to present the research findings in the field of solid biofuels production from biomass. One of the recovery possibilities for waste biomass raw materials is production of solid biofuels. Using a variety combination of influencing variables can be improve the final quality of solid biofuels. Raw biomass material variables influence, especially (type of raw material, particle size, moisture content, compression pressure and compression temperature) can be recognized during the production of solid biofuels. Their effect can be seen through the quality indicators; especially mentioned variables significantly influence the mechanical quality indicators of solid biofuels. Authors would like to present the design of experiment (DOE), evaluation methodology for this experimental plan and research findings which are defining the impact and interaction of influencing variables at densification of selected woods and alternative biomass types. The main goal of this experiment was to obtain such results which can be used for mathematical models design. Designed mathematical models describes the effect and interaction of technological variables and material parameters during densification from the final biofuels quality points of view. These statistical mathematical models based on the proposed experiments are used of the measured data processed and can be very useful tool for final biofuels prediction before densification and thus the densification process can be improved and adjusted according to properties of raw material to be pressed. The final results in the form of mathematical model can be implemented in the production control system which works on the base of experimental research findings in the mathematical algorithms form. Designed mathematical models which describes the densification process at various adjusted levels of influencing variables can control the final quality of solid biofuels during densification.
