Catalisadores à base de Cu, Co ou Fe trocados ou suportados em zeólita USY avaliação na redução de NO com CO
(Universidade Federal de São Carlos, 2008-04-08)
The emissions of the nitrogen oxides (NOx) must be hardly reduced in the next years. The catalytic reduction of NO with CO is one of the possible processes with potential to be able to transform those oxides in N2. In that ...
Influência do método de preparação e performance catalítica para os catalisadores de Pd-La2O3-Al2O3 aplicados na reforma autotérmica do metano
(Universidade Federal de São Carlos, 2008-05-21)
Pd catalysts supported on Al2O3 and La2O3-Al2O3 (12 wt.% La2O3) were
prepared by wetness impregnation method with aqueous solution of of palladium nitrate
(1 wt.% Pd). The supports were obtained by conventional method ...
Influência do método de preparação de catalisadores bifuncionais, Pt-Ni/HUSY, na isomerização do n-hexano
(Universidade Federal de São Carlos, 2008-02-25)
Gasoline containing high amount of linear chain compounds have low
octane number. However, this number can be increased when linear alkanes are
subjected to isomerization, able to change linear chain compounds to ...
Formação de mesoporos na síntese de zeólitas ZSM-5 via nanomoldagem avaliação no craqueamento de n-decano
(Universidade Federal de São Carlos, 2008-04-04)
The use of zeolites in the cracking of hydrocarbons is limited because the molecules higher than 0.74 nm do not diffuse in their micropores. In the other hand, molecular sieves as MCM-41, MCM-48 ou SBA-15, whose diameters ...
