Abstract

ABSTRACT: Porous alumina disk ceramic was decorated with various types of intermediate layers via one-step spray coating-carbonization technique. P-84 (BTDA-TDI/MDI) polymeric solution was sprayed on the alumina disk with an incorporation of intermediate layer. The membrane was carbonized at 700°C under nitrogen (N2 ) atmosphere with a heating rate of 3°C/min. The resultant carbon membrane was characterized in terms of its thermal stability, structural morphology, and gas permeation properties. A high-performance carbon membrane was obtained with the intermediate layer of the alumina powder, which exhibited the best selectivity of O2 /N2, CO2 /N2 and CO2 /CH4 of 4.39, 19.89 and 58.43, respectively.
