摘要：

The partial oxidation of propane to oxygenates (isopropanol, n-propanol, propionic aldehyde and acetone) is attained in a multifunctional three phase catalytic membrane reactor (3PCMR) operating under mild conditions (T-R, 80-120degreesC; P-R, 140 kPa). A comparative testing of different Nation-based catalytic membranes mediated by Fe2+/H2O2 Fenton system has been carried out. The influences of textural and compositional properties and acid functionality on the catalytic performance of the Nafion membranes are outlined. The enhancing effect of the partial heterogenisation of the Fenton system on reaction rate and H2O2 yield is discussed. (C) 2004 Elsevier B.V. All rights reserved.
