Molecular engineering of advanced silicate membranes with controlled pore sizes for feeding oxygen to a catalytic reactor

本项目侧重于甲烷选择性氧化催化膜技术的开发和实施。近年来，该项目的各个方面都取得了重大进展。利用化学气相沉积技术，利用几种类型的有机金属前体形成严格控制的孔结构，膜的发展取得了进展。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渗透率。此外，已经开发出几种催化剂，使用各种金属和载体，能够将甲烷氧化为甲醇、甲醛和二甲醚，对二氧化碳具有显著的选择性。

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.
