MOURA, Juliana Maria Leite Nóbrega de; RIBEIRO, Ana Paula Badan; GRIMALDI, Renato  e  GONCALVES, Lireny Aparecida Guaraldo. Enzymatic membrane reactor and supercritical fluids: process association. Quím. Nova [online]. 2007, vol.30, n.4, pp. 965-969. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422007000400036.

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 extractions reactions with selective separation by membranes through filtration of the supercritical mixture (SCF + extracted solutes). This association provides important energy savings regarding the SCF recompression costs.

Palavras-chave : membrane reactor; supercritical fluids; enzymatic reactor.
