The article presented forecasts for European biofuel production in processes BtL and WtL on the basis of thermochemical technological path. The paper presents the processes of pyrolysis and gasification of biomass leading to the preparation of liquid hydrocarbon fractions in the synthesis of Fischer-Tropsch and processes HTU. Based on the model Koufopanosa, made the right choice of methods to investigate the thermogravimetric kinetics of biomass gasification with a change of enthalpy and identification of degradation products in real time. Presents the results of preliminary tests conducted on the Simultaneous Thermal Analyzer STA 449 F3 Jupiter's Nietzsche. These studies were carried out for samples of cereal straw, crushed to a state of dry dust. Gasification process by subjecting the sample, the test set, recorded curves TG and DSC, and observing the changes in mass, temperature and enthalpy. These studies have been done to pre-determine the conditions under which it may begin the process of liquidation. The study was conducted in an atmosphere of argon / nitrogen and argon / carbon dioxide. The temperature regime provided that the samples were heated to the temperature of500 °C at the heating rate of 3 K/min. Argon was used as protective gas, and N2 and CO2 - as purge gas with flow rates of 30 ml/min. The results, along with discussion, are presented in graphs -derivatograms and charts showing the cumulative weight changes and changes in enthalpy of individual samples.
