Liquid biofuels of the first and second generation - the method of preparation and application

Sustainable economic and industrial growth requires safe, sustainable energy resources. Unfortunately, firstgeneration biofuels are fuels produced from organic matter, which can also be used to produce food or feed. Only second-generation fuels are based on the need for sustainable development and are produced using processes such as pyrolysis, Fischer-Tropsch synthesis or hydrotreating. This paper presents the method for obtaining the first- and second-generation biofuels. Also discussed the possibility of their application.
