Controle da relação de sítios ácidos de Lewis e Brønsted pela incorporação de Sn em zeólitas Y - efeito na seletividade a produtos durante a conversão one-pot de furfural
(Universidade Federal de São Carlos, 2021-02-25)
In the last years, in the production of chemicals or intermediates, the use of bioderived feedstocks as alternative sources to those derived from fossil fuels, has progressively increased. In this context, the conversion ...
Development of stable and high-performance polyaniline activated carbon electrodes for capacitive deionization desalination
(Universidade Federal de São Carlos, 2021-04-19)
Capacitive deionization (CDI) emerged as a cost-effective alternative for the desalination of brackish water (salt concentration lower than 10 g L−1). Significant progress in electrode materials in terms of salt adsorption ...
Monitoramento por espectroscopia dos compostos fenólicos e furaldeídos gerados no processamento de biomassa lignocelulósica
(Universidade Federal de São Carlos, 2017-02-20)
The major process challenge of the second-generation ethanol (2G) production is related
with characterization of hydrolyzate from lignocellulosic biomass, which often contains
high quantities of phenolic compounds and ...
Energy consumption and reaction rate optimization combining turbulence promoter and current modulation for electrochemical mineralization
(Universidade Federal de São Carlos, 2021-02-23)
In the current world scenario, one of the environmental and public health problems that still needs a more efficient intervention is the pollution caused by industrial effluents containing toxic organic compounds, typically ...
Compósitos reticulados de Eversa® Transform e nanopartículas magnéticas como biocatalisadores para a síntese de biodiesel em reator de fluxo em vórtices
(Universidade Federal de São Carlos, 2020-10-30)
The enzymatic production of biodiesel is a promising alternative to the conventional production
