Resumo
This study reports the synthesis, physicochemical characterization by X-ray
powder diffraction (XRD), scanning electron microscopy (SEM) and solid-state
MAS NMR (1H, 23Na, 29Si and 89Y and 119Sn MAS NMR) of a stanno and yttrium
metallosilicate and their application as a heterogeneous catalyst for biodiesel
production via ethanolysis and methanolysis routes using edible, non-edible an
waste oils as feedstocks and environmental remediation. Heterogenous catalytic
studies in the transesterification of refined edible, non-edible, and waste oils have
resulted in high yields of FAMEs and FAEEs (fatty acid methyl and ethyl esters),
nevertheless the highest FAMES (98.2%) and FAEEs (96.6%) yields were obtained
for non-edible microalgae oil extracted from the genetically modified
heterotrophic algal strain Prototheca moriformis. Catalytic studies also using nonedible
macaw palm oil (Acrocomia aculeata) with a high content of free fatty acids
(FFAs) demonstrated that the catalyst could simultaneously perform esterification
and transesterification reactions using using different sources of lipids
feedstocks, notably those that do not compete with food production [1]. On the
other hand, Yttrium metallosilicate were very efficient in the separation, binding
and chemical stabilization of hazardous inorganic, organic and radioactive species
such as lead ( Pb2+, Cd2+, Ba2+ , Cs+ and Sr2+) in aqueous systems.
