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.

该项目的重点是开发和实施用于甲烷选择性氧化的催化膜技术。近年来，该项目的所有方面都取得了重大进展。膜的开发已经使用几种类型的有机金属前体进行，以使用化学气相沉积形成严格控制的孔结构。这些膜能够选择性地分离氧气和甲烷，同时保持进入催化剂床的高氧气渗透性。此外，已经开发了几种催化剂，使用广泛的金属和载体，能够将甲烷氧化为甲醇，甲醛和二甲醚，对CO2具有显着的选择性。
