(Universidade Federal de São Carlos, 2022-08-30)
There is a variety of filter bags available in the market for cleaning gases, composed of different materials, of various sizes, with several surface treatments, high efficiency, and different finishes, which enables the ...
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 ...
Otimização da produção de ácido 3-hidroxipropiônico por Escherichia coli via engenharia metabólica e de processos
(Universidade Federal de São Carlos, 2022-10-14)
The integration of substrates from bioprocesses is of great interest due to the need of destination
for them and the possibility of converting them into value-added products. Among these
substrates, the hydrolysates ...
Utilização do CO2 em substituição ao O2 na ativação de Cu-MAZ na oxidação do metano a metanol
(Universidade Federal de São Carlos, 2022-10-27)
Converting methane to methanol has been a challenge for decades due to the high reactivity of methanol compared to methane. One of the challenges of this reaction to take it to an industrial scale was to find a safer oxidant ...
Synthesis of isoamyl esters from soybean oil deodorizer distillate by enzymatic catalysis for biolubricant applications
(Universidade Federal de São Carlos, 2022-07-26)
Lubricants are among the many products whose manufacture is highly dependent on nonrenewable fossil resources, with high levels of production and a vast marketplace, so they are the focus of many environmental laws around ...
Implementação de sistema nebuloso (“fuzzy”) para controle de oxigênio dissolvido no cultivo de Escherichia coli para expressão de proteínas recombinantes
(Universidade Federal de São Carlos, 2022-04-27)
Due to low oxygen solubility in water and mechanical limitations of a bioreactor, ensuring an adequate dissolved oxygen supply during a recombinant Escherichia coli cultivation is a major challenge in process control. In ...
CuOx-RHO aplicados para conversão de metano em metanol
(Universidade Federal de São Carlos, 2022-05-25)
The direct oxidation of methane (CH4) into higher value-added products, such as
methanol, has recently gained tremendous interest. The challenge is an over-oxidation of
methanol to CO2 and water due to the difficulty in ...
