Abstract: The article presented 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. Preliminary thermogravimetric testing of biomass samples was conducted on the STA 449 F3 Jupiter® coupled with the gases analyzer – spectrometer QMS 403 Aëolos. These studies were carried out for samples of cereal straw, crushed to a state of dry dust. The temperature regime provided that the samples were heated to the temperature of 750 °C at the heating rate of 10 K/min. Gases (nitrogen, argon or carbon dioxide) were used with flow rates of 60 mL/min. The results, along with discussion, are presented in graphs - TG curves and mass spectrum.

Abstract: The growing pressure from the society meant that pollution of the atmosphere by gases of marine engines has become one of the main problems in the protection of the marine environment recent years. Areas of ports like port city or coastal areas are exposed to the impact of pollution from the mainland as well as the considerable impact of harmful compounds contained in the exhaust gas of vessels. In order to determine the share of floating in air pollution and the prevention of the harmful effects of toxic compounds in the exhaust, it is necessary to value the knowledge of marine engines emissions of these compounds from the individual units. This is possible with knowledge of motion parameters of individuals, including their trajectory of motion, the concentrations of individual compounds for these parameters and atmospheric conditions in the region of their presence.The mathematical description of the trajectory of motion of the craft after any track (curve) as a first and essential step in modeling the total emissions of pollutants from internal combustion engines to marine main propulsion of vessels used in the balancing of the pollution is presented in this work.
