Golub N. Scientific and technological bases of renewable raw materials conversion in biohydrogen, biomethane and biodiesel

The dissertation is devoted to the scientific and technological bases of renewable raw material conversion in gaseous and liquid energy carriers using microorganisms. Bases of technological process of energy production are scientifically substantiated. This process combines receiving of biohydrogen or biomethane from renewable raw materials and wastes of biodiesel production from microalgae, that allows to raise efficiency of processes. Conditions that increase the speed of raw bioenergy conversion is determined, also the conditions of energy producing with separation of enzymatic process of biohydrogen (biomethane) obtaining into two stages. The rational technological parameter of biohydrogen (biomethane) production has been found, which allows increasing energy output twice and increasing the concentration of energy carrier in the gas phase by 10%. A mathematical model was designed and a program created that allows researching microalgae growing process. The patterns of process was researched and the rational technological parameters of microalgae cultivation for biodiesel production using extracts from sugar beet and poultry manure was provided.
