The experimental data on the series of experiments (>60) with analysis of the influence of certain range of input parameters on the bio-oil yield and qualitative parameters of output products is presented. The optimization of installation regimes and input parameters for bio-oil yield maximization for different biomass types is performed. It was found that the ratio of three output products is not always optimal maximizing bio-oil yield with respect to energy yield in the products. The maximum achieved bio-oil yield is 51% by mass rated to the input products. It is revealed, that the essential parameters which influence on the final bio-oil yield are temperature in the reactor, time of biomass particles existence in the reactor, fraction of biomass particles. The mass distribution for pyrolysis by-products (pyrogas and biochar) is dependent on the initial moisture content of biomass and organization of condensation process of bio-oil. The energy balance of installation demonstrates the average efficiency of the pyrolysis process on the level of 65% (with maximum 98%) and could be increased to 75% average with simple reconstruction of installation. On the basis of obtained laboratory data the scaling of the installation was performed with development of commercial prototype with productivity of 50 kg/hour. On the basis of obtained technical data, the assessment of economic indicators of bio-oil and biochar production with large sized mobile installation has been performed demonstrating the good commercial feasibility of the installation performance.
