Reator de membrana enzimático e fluidos supercríticos: associação de processos

Abstract: Recebido em 3/7/06; aceito em 28/9/06; publicado na web em 28/5/07 ENZYMATIC MEMBRANE REACTOR AND SUPERCRITICAL FLUIDS: PROCESS ASSOCIATION. The aim of this work is to present the new applications of membrane technology in fat and oil processing, with emphasis on development and applications of the enzymatic membrane reactor and its association with extraction and purification technology by supercritical fluids (SCF). Combining the extraction by SCFs and the separation by membranes allows the integration of ex… Show more

“…Wall and Braun[35] also observed this behaviour in organic compounds in supercritical CO 2 permeation through a hydrophilic micro-porous TiO 2 -membrane. In the same way, Moura et al[36] have found permeate fluxes for modified triacylglycerols nearly null for the BW30 membrane. The authors used a transmembrane pressure of 130 bar and temperature of 40 °C and a pretreatment of the membranes in ethanol (4 h) followed by n-hexane (4 h).…”

“…Recent research on the application of membrane technology to vegetable oils has mainly targeted desolventization (Koseoglu, Lawhon, & Lusas, 1990;Kwiatkowski & Cheryan, 2005;Ribeiro, Moura, Gonçalves, Petrus, & Viotto, 2006); deacidification (Kale, Katikaneni, & Cheryan, 1999;Manjula & Subramanian, 2006;Zwijnenberg, Krosse, Ebert, Peinemann, & Cuperus, 1999); degumming (García, Álvarez, Riera, Álvarez, & Coca, 2006;Kim, Kim, Lee, & Tak, 2002;Koris & Marki, 2006;Marenchino, Pagliero, & Mattea, 2006;Moura, Gonçalves, Petrus, & Viotto, 2005;Pagliero, Mattea, Ochoa, & Marchese, 2007;Subrahmanyam, Rao, Balasubrahmanyam, & Bhowmick, 2006); the synthesis and purification of structured lipids (Moura, Gonçalves, Sarmento, & Petrus, 2007;Moura, Ribeiro, Grimaldi, & Gonçalves, 2007;Xu, Balchen, Jonsson, & Adler-Nissen, 2000); the separation of compounds present in trace amounts in the oil such as antioxidants, and the removal of pigments.…”
