Методичний підхід до обґрунтування оптимальних техніко-економічних характеристик виробництва біодизеля з мікроводоростей

Abstract

Global experience shows that one of the important directions in overcoming the external energy dependence and mitigating its negative consequences for the country is the intensification of the use of its own resource base. Such a measure for Ukraine can be production of analogues of petroleum motor fuel from biological raw materials, namely biodiesel and biobenzine. A significant obstacle in the course of intensification of the use of the existing resource base is the lack of a scientifically based vision of the inland development of technologies for the cultivation and conversion of energy biofeedstock into motor fuel. The article is aimed at developing a methodical approach (based on the provisions of economic theory) to the gradual substantiation of optimal technical and economic characteristics of production for the cultivation and processing of microalgae to biodiesel under the conditions of existing climatic restrictions. The developed methodical approach includes the substantiation of the following: choice of raw materials, choice of method and technology of cultivation, characteristics of cultivation technology, and directly the technical and economic characteristics of production. According to the developed methodical approach, it is proved that microalgae is considered as the energy raw material of the future, while the types of microalgae of the genus Chlorella, and above all the species Chlorella vulgaris, meet the requirements of industrial cultivation the most. The more acceptable for use in the climate of Ukraine method of microalgae cultivation is cultivation in photobioreactors (PBR). The technical and economic indicators of the industrial complex for the cultivation and processing of microalgae in biodiesel indicate the expediency of practical application of the developed methodical approach. The gradual substantiation of the choice of raw materials, the method and technology of cultivation of microalgae when applying the traditional conversion of the biomass allowed to ensure the optimality of technical and economic characteristics of biodiesel production in the climatic conditions of Ukraine.
