Reduction of Typical Diesel NOx Emissions by SCR-NH3 Using Metal-Exchanged Natural Zeolite and SBA-15 Catalysts

Autor: Rodríguez-Castellón, Amanda Pontes Maia Pires Alcantara, Mona Lisa Moura de Oliveira, Jesuína Cássia Santiago de Araújo, Rinaldo dos Santos Araújo, Rita Karolinny Chaves de Lima, André Valente Bueno, Maria Eugênia Vieira da Silva, Paulo Alexandre Costa Rocha, Enrique

Publikováno v: Air; Volume 1; Issue 3; Pages: 159-174

In this work, the catalytic performance of clinoptilolite (CLIN) and SBA-15 catalysts, doped with Fe and Cu, was evaluated in the selective catalytic reduction of NO using NH3 as a reducing agent (SCR-NH3). Both Cu-CLIN and Fe-CLIN were obtained by i

Direct Irradiation Absorption by Nanofluids: A Proposal of Standardization by the Use of the 'Solar Wall'

Autor: Juarez Pompeu de Amorim Neto, Stéphano Praxedes Mendonça, Maria Eugênia Vieira da Silva, Ricardo José Pontes Lima, Paulo Alexandre Costa Rocha

Publikováno v: SSRN Electronic Journal.

We analyzed the behavior of a “Solar Wall” and validated the apparatus with three nanofluids (silver, titanium dioxide and a hybrid compound) in view of their photothermal conversion performance. The factors considered were the temperature gain i
