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 ...
Zeólitas ácidas aplicadas na esterificação catalítica
(Universidade Federal de São Carlos, 2019-03-08)
With respect the sugarcane sector expansion in Brazil, significant quantities of by-products have been generated, among them the fusel oil with potential for reuse due to the high volume produced and its rich isopentanol ...
Contribuições ao estudo da secagem da borra de café em leito vibrofuidizado
(Universidade Federal de São Carlos, 2019-03-15)
Brazil is the largest producer of coffee in the world, half of this production is destined to the soluble coffee industry, that generates a amount of waste. The spent coffee grounds leave the fabrication processo f the ...
Extração e caracterização cinético de lipase ácida presente na semente de mamona
(Universidade Federal de São Carlos, 2019-02-26)
Several studies have been conducted regarding acidic lipase from castor bean seed, most of them using the enzyme in the form of solid seed extract (SSE), which is extracted through grinding and removal of the oil. Kinetic ...
