Hidrogenação de CO2 sobre catalisadores à base de elementos não-nobres: a influência da composição química do catalisador e de condições reacionais na produção de álcoois
(Universidade Federal de São Carlos, 2022-11-30)
Strategies to reduce CO2 emissions and control the increase in atmospheric levels of this gas are urgent. A promising approach to help minimize the accumulation of CO2 in the atmosphere and the corresponding negative ...
Modelagem matemática aplicada ao estudo de células a combustível a etanol direto
(Universidade Federal de São Carlos, 2022-03-09)
The current fuel cell market is dominated by Hydrogen cells. Nevertheless, due to Hydrogen’s high reactivity, the difficulty in storage and the lack of infrastructure to distribute it, Hydrogen cells might not be the most ...
Estudo da reação de hidrogenação de CO2 em materiais à base de Cu via catálise heterogênea
(Universidade Federal de São Carlos, 2022-07-07)
CO2 is a greenhouse gas whose production has intensified in recent decades, generating its accumulation in the Earth’s atmosphere. Thereby, numerous negative environmental changes, such as the aggravation of the greenhouse ...
Catalisadores NiMo/γ-Al2O3 aditivados com Nb - Atividade para a hidrodessulfurização de tiofeno
(Universidade Federal de São Carlos, 2021-04-30)
The burning of fuels in the industry or in vehicle engines is a direct agent in the generation of the atmospheric pollution through the emission of contaminating gases such as NOx and SOx. To minimize this impact, environmental ...
