要約

The use of microalgae for biofuel production is one of the most popular ways for fossil fuels substitution. There is a number of microalgae-to-biofuel conversion methods with different target products (biodiesel, bioethanol, biobutanol, bio-oil, biochar, biomethane, biohydrogen etc.). One of the promising technologies that show a significant increase of references in literature in the last few years is hydrothermal liquefaction (HTL) of microalgae with bio-oil production. Here we discuss the advantages of HTL method and its current important issues. One of the main problems of HTL is the search of optimal strains and cultivation conditions that provide high biomass productivity with optimal biochemical composition. In case of HTL the reduction of nitrogen content in feedstock is one of important issues. Using our own experience in microalgae cultivation we discuss about the possibility of obtaining the optimal microalgae biochemical composition for the processing that includes HTL. Also we discuss about the processing ways with HTL and about the influence of extraction of high-value compounds from microalgae on the efficiency of production of bio-oil and its quality.
