Abstract:
Biodiesel, mainly obtained by transesterification of vegetable oils or animal fats, is increasingly considered a sustainable alternative to fossil fuels due to its renewable nature and low environmental impact. However, the raw mixture produced by this process has functional limitations, in particular poor oxidation stability and non-optimal behavior at low temperatures, which prevent its direct use in engines. To overcome these problems, a qualitative improvement process is needed, consisting in the partial hydrogenation of the polyunsaturated chains of FAMEs (fatty acid methyl esters), with the aim of obtaining monounsaturated compounds without reaching complete saturation. In this work, an innovative nickel-based catalyst supported on steel slag (SS), a waste material of the steel industry, chosen for its structural and basic properties, has been developed. The catalytic system was employed in a partial hydrogenation for obtaining a biodiesel blend with a high content of C18:1 chains, representing an improvement in performance and fuel quality.
