Abstract:

Conversion of biomass is a research field that has taken increasingly more importance since carbon­based fuels and chemicals can be produce in a sustainable/renewable way. In this work, we report the study on alternative catalysts for hydrodeoxygenation (HDO) based on nickel as active metal.The HDO reactions were carried out in a 200ml batch autoclave. The nickel catalysts were produced by wet impregnation using different supports, like alumina, silica, titania, zirconia and active carbon. The liquid products of the reaction were analysed using Karl Fischer titration, elemental analysis andgas chromatography. The extend of the catalyst poisoning was evaluated by analysing the catalysts after the reaction bySEM-EDX (scanning electron microscopy), TGA (thermogravimetric analysis) and elemental analysis. Among the nickel-based catalysts, NiCu/Al2O3 showed a higher activity. The use of the catalysts permitted to obtain a reduction of oxygen content in the upgraded oil products in comparison to the original feed. The oxygen content was in general inferior to 26% under mild conditions and the water content in the upgraded oil was under 10%. In the GC-MS analysis, hydrogenated products were detected. Coke deposition was identified as the main poisoning for the catalysts.
