Abstract
As already well established, the products of biomasses pyrolysis can be important in the exploration of alternatives to the use of fossil fuels. The study of the kinetic mechanism of thermal degradation of biomasses requires the knowledge of thermodynamic properties of the species, molecules and radicals, involved in the reaction path. These properties have been estimated by using the group contributions method and the program THERM. Particularly in the case of radicals the use of THERM can be difficult and, as an alternative, here is proposed a criterion based on analogy rules (isodesmic method). The obtained properties have been tabulated and compared with the experimental data where available. Moreover a comparison among the methods has been performed. A useful databank for several oxygenated compounds involved in biomasses pyrolysis has been obtainedFile | Dimensione | Formato | |
