“…Their primary components are methane, hydrogen, and carbon monoxide and depending on the utilised method also ethane, or higher hydrocarbons and inert gases such as carbon dioxide and nitrogen. This gaseous mixture can be subsequently purified and used for chemical production (including synthetic fuel production) or direct use in cogeneration units [7]. Use of these fuels for engine propulsion has been researched, but due to the influences of the boundary conditions such as chemical composition and physical properties of the substrate, method used for gasification/pyrolysis, type of the reactor, conditions inside the reactor (temperature, pressure) and subsequent chemical treatment large variety of syngas mixtures may be obtained [9].…”
