Estudo da dinâmica do escoamento gás-sólido em resfriadores de catalisador de FCC usando fluidodinâmica computacional (CFD)
(Universidade Federal de São Carlos, 2017-01-26)
The fluid catalytic cracking (FCC) is an important process in oil industry, since it converts heavier fractions in lighter ones, which are more valuable. The catalyst particles (typically m) are deactivated during the ...
Influência da adição de Co nas propriedades de catalisadores à base de Ni suportados em MgAl2O4 aplicados na reforma a vapor do ácido acético
(Universidade Federal de São Carlos, 2016-03-28)
The steam reforming of acetic acid (SRAcH), a model compound of pyrolysis-oil, was studied over MgAl2O4-supported Co-Ni catalysts with different Co/Ni ratios, prepared by impregnation using the incipient wetness method. ...
Hidrotalcitas multimetálicas para produção de gás de síntese a partir do biogás
(Universidade Federal de São Carlos, 2015-03-18)
In this work, catalysts derived from hydrotalcites were employed in Direct Reforming of Biogas, once they feature the necessary basicity to allow and improve carbon removal during reforming. As a differential study, the ...
