| Research Abstract |
Silica hybrid membranes were developed for a high temperature hydrocarbon separation. The membranes were prepared by using a counter diffusion chemical vapor deposition (CVD) method that uses two reactants. The deposition was performed at 450 for 5 min by using hexyltrimethoxysilane and O2 as a silica source and an oxidant. Permeance ratio of propane/propylene at 270 °C through the silica hybrid membrane was 414 with the propane permeance of 1.0×10-8mol m-2s-1Pa-1. The permeance ratio was more than four times larger than that for our objectives. The permeance ratio is the maximum value for the high temperature propane permeselective membranes at this moment.
