Escuela de Ingenierías Industriales K1 Termodinámica K1 Gas natural AB The research developed in this PhD thesis aims at contributing to the development and introduction of new gaseous fuels from renewable sources in the European energetic mix through the thermodynamic characterization of mixtures containing the main components of these alternative fuels.The work provides high accurate experimental (p, ρ, T) data of three (CH4 + He) binary mixtures with concentrations of (5, 10 y 50 mol-% He), a synthetic non-conventional gas mixture type CMM (coal mine methane) composed by ten components and containing 64 mol-% of methane and a synthetic biogas-like mixture composed by four components and containing 50 mol-% of methane. Nine isotherms between (240 y 400) K and up to 20 MPa of pressure were carried out for the (CH4 + He) binary mixtures, seven isotherms between (250 y 400) K and up to 15 MPa for the CMM mixture and six isotherms between (275 y 400) K and up to 20 MPa for the biogas-like mixture. The second and the third interaction virial coefficients for the (CH4 + He) binary mixtures were also estimated.
