Mitigação dos inibidores gerados no pré-tratamento da biomassa vegetal: impacto técnico-econômico-ambiental de diferentes rotas de processo na biorrefinaria
(Universidade Federal de São Carlos, 2021-04-27)
The presence of inhibitors is still an economic bottleneck that needs to be resolved in order to make 1G2G ethanol biorefineries feasible, requiring the development of technologies capable of improving their competitiveness ...
Estruturas de controle de biorreator baseadas em fluxos metabólicos para fermentações micro-aeradas
(Universidade Federal de São Carlos, 2021-04-15)
The supply of oxygen as a limiting nutrient in bioreactors is a challenge, as microorganisms may have different metabolic requirements, besides the difficulty of measuring this variable in low levels. Despite the obstacles, ...
Fluidodinâmica e transferência de calor em leitos de jorro visando a secagem de grãos de Sorgo: análise experimental e simulação numérica por CFD-DEM e TFM
(Universidade Federal de São Carlos, 2021-04-23)
Simulations of granular flows in spouted beds are carried out following two main approaches: two-fluid model (TFM) and CFD-DEM coupling (Computational Fluid Dynamics/Discrete Element Method). Moreover, the fluid dynamics ...
