Síntese de titanatos alcalinos e avaliação na transesterificação catalítica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2012-06-11)
Three methods for the synthesis of sodium titanates were investigated: solid state treatment (800 oC), hydrothermal treatment (110 oC) and sol-gel method (55 oC). The titanium oxide was used as starting compound for ...
Avaliação do catalisador CTA-MCM-41, modificado por poliacrilatos, na transesterificação de monoéster
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 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 ...
Síntese da CTA-MCM-41 a partir de trissilicato de sódio e avaliação na transesterificação de ésteres
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2014-02-25)
The increasing demand for it in today s world and the problems caused by fossil fuel usage lead to a search for alternative sources that may integrate the world s energy matrix. In this context, because this product is ...

(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2020-02-28)
The synthesis of biodiesel, through transesterification, occurs industrially in the presence of basic homogeneous catalysts, where others steps are necessary, such as washing and neutralization of the final product due to ...
Síntese e avaliação de sílica tipo M41S contendo cátions CTA em transesterificação catalítica
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2010-08-13)
The investments in the biofuel production have increased a lot in the last years mainly because of smaller damages they cause to the environment in comparison with the derived conventional petroleum fuels. The reaction of ...
Modelagem e análise experimental da transesterificação do óleo de soja através de microondas
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Química, 2016-06-03)
In recent decades, biodiesel production techniques through the transesterification of
oils or fats have been intensified. This is due to the increasing demand for energy
sources more "clean" (less polluting the environment), ...
