Estudos sobre a acessibilidade aos sítios de zeólitas para aplicação em catálise básica
(Universidade Federal de São Carlos, 2022-03-28)
The application of zeolites in catalysis is restricted when bulkier molecules are involved, for example, in the manufacture of fine chemicals, where the reactant molecules are unable to access their micropores. A solution ...
Aproveitamento de CO2 para a produção de metanol e compostos C2+ aplicando catalisadores à base de Cu e Fe
(Universidade Federal de São Carlos, 2021-08-10)
Considering the approaches to use of the CO2, this work aimed to study CO2 hydrogenation at gas phase and CO2 reduction (CO2RR) via electrocatalysis. Through these methodologies a wide variety of value-added products can ...
Análise de diferentes configurações do leito de jorro com agitador mecânico e do equipamento convencional
(Universidade Federal de São Carlos, 2022-03-24)
The mechanical spouted bed emerged as a modification of the conventional spouted bed
to minimize problems in the movement of solids and the need for high air flows just for
the existence of the spouting regimen. Therefore, ...
Influência do agente precipitante na síntese de catalisadores Cu-ZrO2 aplicados na conversão de glicerol a acetol e propilenoglicol
(Universidade Federal de São Carlos, 2021-07-23)
Biodiesel production by transesterification reaction generates large amounts of glycerol as a by-product. The development of chemical routes to use glycerol as raw material for products with high added value is essential ...
Análise técnico-econômica-ambiental da produção integrada de etanol e biodiesel no contexto brasileiro
(Universidade Federal de São Carlos, 2023-03-31)
The Greenhouse Gas (GHG) emissions must be reduced, it is a global emergency. Biofuels, such as ethanol and biodiesel, are indispensables parts of the brazilian renewable energy matrix, and has an essential place when ...
