Catalisadores de Ni/Al2O3 promovidos com Au e Ag aplicados à reforma a vapor do metano
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2005-04-08)
15%Ni/Al2O3 catalysts was obtained by impregnation with Ni(NO3)2
aqueous solution and promoted with Au and Ag. The Au was successively
impregnated with aqueous solution of [Au(NH3)4](NO3)3. The Ag was coimpregnated
with ...
Estabilidade térmica de polímeros hidrossolúveis
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2016-07-21)
The study of thermal degradation of polymers is essential to determine the stability of the structure and depends on the physical state where the polymer is. A comparative study of the thermal stability of kappa carrageenan ...
Degradação termocatalítica do petróleo pesado utilizando sílica bimodal meso-macroporosa
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIA E ENGENHARIA DE PETRÓLEO, 2020-02-21)
Petroleum is responsible for a large part of the energies and is currently used due to the intense
consumption of its derivatives in fuel engines, industries and commercial products. In your
exploration and production, ...
