Currently the challenge is the development of new technologies that will allow the purification of the biomass
residues obtaining biomass feed stocks and consequently intermediate platforms, building blocks, secondary
chemicals, intermediates and finally high valuable chemicals for products used in pharmaceuticals, foods, agriculture
and materials. The production of value added chemicals from biomass derived carbohydrates is an emerging field.
The amount of publications in the study of pentose and hexose conversion to furfural and 5-hydroxymethylfurfural
(HMF) has considerably increased in the recent years. Specifically, HMF is considered to be one of the most
promising platform molecules that can be converted into a variety of interesting chemicals through decarbonylation,
decarboxylation, hydrogenation, aldolcondensation, etherification, amination and hydrogenolysis reactions, among
others. The valorisation of biomass residues using heterogeneous catalysis has been an important improvement in
the fine chemistry field. HMF derived is useful in manufacturing of important products as acids, aldehydes, alcohols
and amines. In this work, the selective amination and hydrogenation of HMF through heterogeneous catalysts is
proposed to obtain high added value products. Hydrogenation allowed obtaining biofuel additive compounds and
the direct reductive amination of HMF using heterogeneous catalysts and NH3 is presented for first time. In that
sense, this work includes the study of different preparation procedures of catalysts and different metal precursors,
supports, co-catalysts to modify the metal particle size, metal loading and dispersion, acidity of solids and reactions
conditions. The catalytic behavior was analyzed by activity, selectivity and stability of the solids. Both in amination
and hydrogenation, some properties as the metal or support nature, metal diameters and the acidity of solids were
changed considerably by the conversion and yield to the value added products from HMF. This catalytic behavior was
related to the solid properties through different characterization techniques, but in most experiments a maximum
conversion was obtained.
