Resum:
Due to the current worldwide political scenario and lack of energy sources, biomass has been proposed as one of the alternative and sustainable raw materials to address the urgent need for renewable energy resources. This thesis focuses on furfural which is considered one of the most value-added chemicals derived from biomass. We synthesized different catalysts to be used for the hydrogenation of furfural, converting it into commodity chemicals such as 1,2-pentanediol, 1,5-pentanediol, furfuryl alcohol and tetrahydrofurfuryl alcohol. These furfural´s derivatives may utilize in the production of biofuels, the production of polymers, as fuel additives, solvents, etc. All used catalysts were prepared based on non-noble metals (Ni, Co, Cu, Mg, Al), and derived from layered double hydroxides (LDHs). Next, they were calcined under air at 673 K for 4 hours, reduced under pure H2 at 773 K for 1 hour and characterized by XRD, FESEM-EDX, H2-TPR, TPD-NH3, ICP and BET. The catalyst performance was tested in two different types of reactors, the continuous packed-bed reactor (PBR) and the high-pressure slurry reactor (SSR).
