Keywords: diesel biofuel, transesterification, hydraulic pump, Reinold’s number, hydraulic mixing, energy efficiency

Abstract

Diesel biofuel is mainly received in the process of transesterification, due to the interaction of vegetal oil and methyl spirit under catalysts presence. Methyl spirit, catalyst and oil create a multiphase medium in which the reaction process is going slower. To speed up the transesterification reaction it is necessary to create the emulsion with an increased area of reagents contact, which can be done by means of constant mixing. An efficient mixing determines the completeness of the process of transesterification and effects both qualitative and quantitative indexes of diesel biofuel output.

To achieve the above mentioned it was proposed an improved mathematical model for emulsion mixing process in reactor-mixer with disk injector and main parameters for reactor-mixer and disk injector were received. This disk injector can be used for removing the received diesel biofuel from a reactor-mixer after the technological operations of transesterification and sedimentation. A disk injector enables to pump the received biofuel beginning from the upper part of a reactor-mixer that prevents glycerine from getting into the biofuel. The application of disk injectors in mixers makes it possible to produce diesel biofuel on a simplified technology as well as to remove it fully from the mixer under the conditions of farming. In a process of a four-time emulsion pumping on a closed circuit and after a proper sedimentation we received diesel biofuel with a coefficient of kinematic viscosity 4.25 mm2 /sec and a flash temperature 125 °C. A lower calorific value of a received diesel biofuel was 36.96 MJ /kg. The output of diesel biofuel was 85.6 % from a utilized rape oil.
