Novel Platform for Enhanced Membrane Reactors for Homogeneous Catalysis

Membrane reactors have been proposed for a number of syntheses. However, to be competitive with conventional technologies, membrane reactors must provide better selectivity, permeability, and stability. This project will develop a novel platform with enhanced membrane permeability and stability, as needed for broad membrane reactor utilization. In Phase I, a chemically resistant membrane reactor, based on novel composite membranes, was fabricated. Large improvements in reaction rate, yield, and subsequent ease of downstream separation were demonstrated. The results suggested 35% energy savings. Phase II will fabricate larger prototype hollow fiber membrane reactors, which will provide not only the needed chemical and thermal resistance but also the desired flux and separation properties. Enhanced homogeneous catalysis will be demonstrated for specific esterification processes. The system will be field tested, and an economic evaluation will be performed. Commercial Applications and Other Benefits as described by the awardee: The enhanced membrane reactors should impact a broad platform of chemical reactions that produce over 5 billion pounds of product annually. Over 50 trillion BTU of energy could be saved each year.
