Otimização da produção de etanol 2G a partir de hexoses e pentoses
(Universidade Federal de São Carlos, 2014-02-27)
The industrial production of fuel ethanol and sugar generates the main byproduct of sugarcane bagasse, which is burned in boilers for power generation. However, as a lignocellulosic material (consisting basically of three ...
Secagem de sólidos porosos granulares
(Universidade Federal de São Carlos, 2014-07-18)
In the present work, an experimental study about heat and mass transfer phenomena was carried out during drying of porous media when subjected to an upward flow of heated air. The cylindrical porous media consisted of ...
Purificação de penicilina G acilase produzida por Escherichia coli e Bacillus megaterium recombinantes
(Universidade Federal de São Carlos, 2014-03-28)
Penicillin G acylase (PGA) is the key enzyme for the industrial production of β-lactam antibiotics. Major current PGA demand is attended for producer organisms as Escherichia coli and Bacillus megaterium genetically ...
Projeto, construção e desenvolvimento metodológico de um aparelho de destilação. Estudo de caso: produção de etanol anidro via destilação extrativa utilizando glicerol
(Universidade Federal de São Carlos, 2014-03-18)
Ethanol is a renewable fuel produced from biomass. Starting in 1975, Brazil began a national program to promote ethanol production in large scale, the ProAlcool Programme. In the harvest 2012/13 it was produced 23.64 billion ...
Catalisadores à base de Cu, Zn, Al e Ce aplicados à reação deslocamento gás-água
(Universidade Federal de São Carlos, 2014-03-26)
The water gas-shift reaction (WGS) is an important step in the production process and purification of H2 from hydrocarbon. Commercially, to overcome the thermodynamic and kinetic limitations, this reaction occurs in two ...
