Polymer-immobilized aluminium or copper tungstophosphates and tungstosilicates as new catalysts in anisole acylation
(Elsevier Science, 2006)
New materials with spherical shape were obtained from aluminium or copper salts of tungstophosphoric and tungstosilicic acids immobilized in a polymeric blend prepared with polyvinyl alcohol and polyethylene glycol by the ...
Occurrence of dead core in catalytic particles containing immobilized enzymes: analysis for the Michaelis–Menten kinetics and assessment of numerical methods
(2016-11-01)
In this article, the occurrence of dead core in catalytic particles containing immobilized enzymes is analyzed for the Michaelis–Menten kinetics. An assessment of numerical methods is performed to solve the boundary value ...
Seleção de suportes e protocolos de imobilização de lipases para a síntese enzimática de biodiesel
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2009-05-25)
The objective of this thesis was to prepare and select immobilized lipase derivatives with high catalytic activity and thermal stability to mediate the biodiesel synthesis from palm and babassu oils by ethanolic route. The ...
A new application of humic substances: Activation of supports for invertase immobilization
(2000-12-01)
Invertase was immobilized on aminopropyl silica (APTS-SiO2) activated with humic substances (APTS-SiO2-HS) and on aminopropyl silica activated with glutaraldehyde (APTS-SiO2-GA). The resulting activity of both systems was ...
