Synthesis and Recognition of a Nano- Composite Ceramic Membrane for Hydrogen Purification, M.Sc. Thesis Sharif University of Technology ; Safe Kordi, Ali Akbar (Supervisor)
Abstract
In this work, we have tried to synthesize, recognize and evaluate the performance of a composite ceramic membrane to purify hydrogen and obtain high H2 separation values from other gases such as methane, carbon dioxide and nitrogen at high operating temperatures (837- 1073 K). The membrane was prepared by modification of a tubular alpha- alumina support with a series of gamma- alumina layers using sol- gel method. The membrane was then covered with a Nano-composite silica- alumina layer using CVD method. The thickness of this layer is estimated to be around 80- 100 nm and with a completely dense structure. EDX, XRD, DLS, BET and mercury porosietery analysis plus SEM and FESEM images were...
