Abstract


The properties of biodiesel depend on the chemical structure of individual fatty acid methyl esters. In this the chemical structure of fatty acid chains was modified by high-pressure, high temperature treatment with a hydrogen rich gas, obtained through the alkaline electrolysis of water, in the presence of Pt as a catalyst. The effect consists in the breaking of the long unsaturated carbon chain of fatty acids methyl esters with the forming of new more volatile compounds, with a shorter and more saturated carbon chain. The hydrogen rich gas presents real applicability in the production of second generation biofuels, but a strict kinetic control and the use of catalyst with high specificity is recommended.
