Claudia Prestigiacomo main research areas are:

•            Waste valorization through hydrothermal liquefaction process: Hydrothermal liquefaction (HTL) process is considered a promising route to convert a wet biomass into a fuel precursor called biocrude (BC). The main role of HTL, in fact, is to decompose a wet matrix in simpler molecules and its first step is the hydrolytic cleavage of the constituent bio-macromolecules. The process has been mainly investigated in hot (200-400°C) and compressed water (50-280 bar) as solvent.

•              Molten salts based thermochemical processes: Molten salt driven catalytic processes offers a new and emerging technology approach for treating organic wastes to achieve negative CO2 emissions and a circular carbon economy by converting the low-value carbon content of the waste into high value solid carbon materials which can be reused, and also converting the hydrogen content of the waste into a low-carbon hydrogen-rich fuel gas.

•            Biodiesel production from vegetable oils: Study different heterogeneous catalytic systems to produce biodiesel from vegetable oils through the interesterification process. As an alternative to transesterification, the interesterification reaction uses methyl-acetate instead of methanol as acyl-donor with the production of triacetin, a compound that can be used as plasticizer agent in polymers, but also as additive of biodiesel, as it is soluble in it up to 10 wt% and it can improve several biodiesel properties (such as oxidative stability and cold flow) and fuel yield.
