(Universidade Federal de São Carlos, 2021-08-26)
This study investigated drying aroeira (Schinus terebinthifolius Raddi) leaves in a rotating dryer with a perforated wall to evaluate the influence of operating conditions in the preservation of color, and bioactive compounds ...
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 ...
Formação do carbonato de glicerol por transesterificação catalítica heterogênea
(Universidade Federal de São Carlos, 2022-04-29)
The industrial production of biodiesel has generated large amounts of glycerol, transforming this co-product into raw material for other processes. Notably, glycerol carbonate has emerged as a promising substance for the ...
