Catalytic conversion of saccharides into furan derivatives
The research was focused in Catalysis, Material Science (catalyst synthesis). More specifically in homogeneous and heterogeneous acid and base catalysis. In particular in the conversion of saccharides into the platform chemicals: furfural (FUR) and 5-hydroxymethyl-2-furaldehyde (HMF), in the liquid-phase, via batch operation mode. Development of analytical methodologies for catalyst screening. Experiments planning and interpretation of experimental results. Identification, synthesis and characterization of heterogeneous bulk and supported catalysts with improved texture, acid-base properties and catalytic properties (e.g. micro/mesoporous aluminosilicates, composite materials, delaminated layered zeolites, mixed oxides)
Sérgio Lima has a Ph.D. in Chemistry and a Degree in Chemistry (Analytical Chemistry) by University of Aveiro, Portugal. His previous research experience was related with the development of heterogeneous (and homogenous) catalytic processes for valorisation of alternative renewable feedstocks (eg. carbohydrate biomass and CO2) for chemical/fuel production and recycling using thermochemical catalysed processes, in the liquid phase under batch or continuous (high-pressure) reaction mode. He has accumulated experience in chemical valorisation of carbohydrate biomass and CO2; identification, preparation and characterisation of fully inorganic porous catalysts with improved texture, acidity and stability such us microporous and mesoporous and nano-sized materials and in the development of ionic liquid-based catalytic routes. In his PhD, Sérgio Lima has been involved in the investigation of the effects caused by strong electrolytes on the inclusion and self-aggregation processes of amphiphilic molecules in aqueous solutions containing cyclodextrins. These studies were performed in collaboration with Doctor José Teixeira from Laboratoire Léon Brillouin (CEA/Saclay, France) using Small Angle Neutron Scattering (SANS) and 1H NMR.
His scientific interests includes: valorisation of alternative feedstocks (bio-renewable substracts, eg. carbohydrate biomass and CO2) for chemical/fuel production and recycling using thermochemical catalysed processes; development of catalytic technologies; design, constrution and commissioning flow reactors (from bench-top microreactor to pilot-plant); rational design, synthesis and characterization of heterogeneous catalysts; spectroscopy; analytical chemistry; colloidal chemistry; chemical engineering and supramolecular chemistry.
As result of his research activities as PhD student and postdoctoral researcher resulted in: 1 PhD thesis, 2 book chapter, 1 review, 33 papers in international journals of the scientific citation index (SCI) and 5 papers in proceedings books. He is co-author of more than 30 posters communications and 3 oral communication presented at (inter)national congresses/conferences. Furthermore, he was responsible for preparations of draft manuscripts, grant applications, resumes, research plans and projects. Finally, he was also responsible for the preparation of confidential reports for industrial partners.
