Project Period (FY)	2017-10-13 – 2020-03-31
Keywords	CH4 partial oxidation / methanol formation / dimethyl ether formation / formaldehyde formation / silica membrane / chemical vapor deposition
Outline of Annual Research Achievements	This project focuses on the development and implementation of catalytic membrane technology for the selective oxidation of methane. Significant progress was made in the recent year on all aspects of the project. Membrane development has progressed using several types of organometallic precursors to form tightly controlled pore structures using chemical vapor deposition. These membranes are capable of selectively separating oxygen and methane while maintaining a high oxygen permeance into the catalyst bed. Additionally, several catalysts have been developed using a wide range of metals and supports capable of oxidizing methane to methanol, formaldehyde and dimethyl ether with significant selectivity over CO2.
