Influência da morfologia e do cisalhamento na produção de enzimas celulolíticas por Aspergillus niger
(Universidade Federal de São Carlos, 2020-03-26)
Issues related to sustainability and development of renewable and less polluting processes are increasingly in evidence, due to the various environmental crises and a greater concern with the scarcity of non-renewable ...
Contribuições da engenharia de sistemas em bioprocessos à transição para a economia neutra em carbono: análise tecno-econômica-ambiental de biorrefinarias
(Universidade Federal de São Carlos, 2020-03-16)
R&D of (bio)chemical processes should include economic analysis and environmental assessment since the early stages of research, to improve the chance of successful industrial implementation. Process Systems Engineering ...
Esterificação de glicerol com ácido benzoico sobre zeólitas H-ZSM-5 hierárquicas incorporadas com Zr ou Nb
(Universidade Federal de São Carlos, 2020-03-19)
Acid zeolites are microporous aluminosilicates, which exhibit negative charged AlO4- tetrahedrons in its lattice balanced by protons (H+), generating Brønsted acid sites (BAS). The Lewis acidity of zeolites is commonly ...
