Avaliação do catalisador CTA-MCM-41, modificado por poliacrilatos, na transesterificação de monoéster
(Universidade Federal de São Carlos, 2014-03-24)
The silica hybrid CTA-MCM-41 (where CTA is the cetyltrimethylammonium cation) was synthesized and used in the transesterification of ethyl acetate with methanol. This is a model reaction used to test basic catalysts for ...
Propriedades catalíticas de aluminossilicatos funcionalizados com propilaminas
(Universidade Federal de São Carlos, 2023-03-17)
In this work, the functionalization with aminopropyl-trimethoxysilane (APTMS) of aluminosilicates precursors of the Na-LTA zeolite was explored in the synthesis of basic catalysts for the Knoevenagel condensation. The ...
Reforma autotérmica do metano: estudo do Processo e de catalisadores
(Universidade Federal de São Carlos, 2005-05-07)
The study of the autothermal reforming of methane over Ni/γ-Al2O3 catalyst, promoted with noble metals was the objective of this work.
In the first part, the stability to coke deposition of the autothermal reforming was ...
Estudo da influência de baixos teores de platina em catalisadores Ni/γ-Al2O3 nos processos de reforma a vapor, oxidação parcial e reforma oxidativa do metano.
(Universidade Federal de São Carlos, 2002-08-22)
The effect of platinum addition in low contents (0.1 and 0.3 % wt.) in nickel supported γ−alumina catalyst (15% Ni wt.) has been investigated. The samples were prepared by successive wet impregnations of metal ions over ...
