Síntese de nanopartículas de ouro por precipitação
(Universidade Federal de São Carlos, 2012-04-26)
Gold nanoparticles have properties with great interest in applications in biomedicine, catalysis, optics and electronics. This study seeks to produce stable, size-homogeneous and well-dispersed particles. The chosen method ...
Craqueamento de cicloexano sobre zeólitas ácidas : atividade, seletividade e influência da presença de mesoporosidade
(Universidade Federal de São Carlos, 2012-03-30)
The need to develop a catalyst capable of processing heavy oil fractions, which is extracted from deeper wells, is essential. This concern has become more remarkable with the discovery of new oil fields in Brazil. This ...
Degradação eletroquímica de compostos fenólicos usando eletrodo de diamante dopado com boro
(Universidade Federal de São Carlos, 2012-03-22)
The presence of organic compounds in industrial effluents is a serious environmental issue as well as for the human health, since most of those compounds are extremely toxic. The treatment of those effluents is done many ...
Catalisadores Ni/BaO-Al2O3 e Ni/BaO-SiO2 para reforma do metano com CO2
(Universidade Federal de São Carlos, 2012-04-26)
In this work the activity of nickel catalysts were appraised regarding the dry reforming of methane. Due to the low surface area, the catalysts were supported on SiO2 and Al2O3, in order to verify the effect of the support ...
Catalisadores de Mo suportados sobre sílica, sílica-titânia ou sílica-zircônia promovidos por Co ou Ni: avaliação do método de preparação e da composição do suporte na atividade para HDS
(Universidade Federal de São Carlos, 2012-04-30)
Hydrodesulfurization (HDS) catalysts containing Mo, NiMo or CoMo were supported on silica, silica-titania and silica-zirconia. These supports were synthesized by the sol-gel method, using citric acid as an agent to pore ...
