    • Acetylation of Eugenol on Functionalized Mesoporous Aluminosilicates Synthesized from Amazonian Flint Kaolin 

      Oliveira, Alex de Nazaré de; Leite Lima, Erika Tallyta; Aguiar Andrade, Eloisa Helena de; Zamian, José Roberto; Rocha Filho, Geraldo N. da; Ferreira da Costa, Carlos Emmerson; Oliveira Pires, Luíza Helena de; Luque, Rafael; Santos do Nascimento, Luís Adriano (MDPI, 2020)
      The present work was aimed to investigate the catalytic activity of a mesoporous catalyst synthesized from 3-mercaptopropyltrimethoxysilane (MPTS) functionalized Amazonian flint kaolin in the acetylation of eugenol with ...

    • Acetylation of Eugenol over 12-Molybdophosphoric Acid Anchored in Mesoporous Silicate Support Synthesized from Flint Kaolin 

      Nazaré de Oliveira, Alex de; Leite Lima, Erika Tallyta; Terra de Oliveira, Deborah; Simões Angélica, Rômulo; Aguiar Andrade, Eloisa Helena de; Rocha Filho, Geraldo N. da; Ferreira da Costa, Carlos Emmerson; Fernandes Costa, Fabiola; Luque, Rafael; Santos do Nascimento, Luís Adriano (MDPI, 2019)
      A new prepared catalyst, 12-molybdophosphoric acid (HPMo) anchored to the mesoporous aluminosilicate AlSiM, synthesized from Amazon kaolin, was characterized and used as a heterogeneous acid catalyst for the production of ...

    • Bentonites Modified with Phosphomolybdic Heteropolyacid (HPMo) for Biowaste to Biofuel Production 

      Nazaré de Oliveira, Alex de; Barbosa de Lima, Marco Aurélio; Oliveira Pires, Luíza Helena de; Rosas da Silva, Moisés; Souza da Luz, Patrícia Teresa; Angélica, Rômulo S.; Rocha Filho, Geraldo N. da; F. da Costa, Carlos Emmerson; Luque, Rafael; Santos do Nascimento, Luís Adriano (MDPI, 2019)
      Two bentonites from Paraíba (Northeastern Brazil) were impregnated with heteropoly phosphomolybdic H3PMo12O40 (HPMo). The materials produced were characterized by various techniques such as N2 adsorption-desorption (specific ...

    • Glycerol and Catalysis by Waste/Low-Cost Materials—A Review 

      Farias da Costa, Ana Alice; Oliveira, Alex de Nazaré de; Esposito, Roberto; Len, Christophe; Luque, Rafael; Rodrigues Noronha, Renata Coelho; Rocha Filho, Geraldo N. da; Santos do Nascimento, Luís Adriano (MDPI, 2022)
      The growing global demand for renewable energy sources can be reached using biofuels such as biodiesel, for example. The most used route to produce biodiesel is the transesterification reaction of oils or fats with short-chain ...
