Project Description

Arizona State University, in collaboration with Media and Processes Technology Inc., the University of Cincinnati, and Nexant Inc., will develop a bench-scale zeolite membrane reactor for water-gas shift (WGS) reaction with carbon dioxide (CO2) capture. The project is based on the previous successful lab-scale validation of a stable, hydrogen (H2) semi-permeable MFI-type zeolite membrane reactor. The research includes scaling-up the synthesis of zeolite membrane tubes; design and fabrication of the membrane reactor modules; testing bench-scale zeolite membrane reactors; and process design and techno-economic analysis of the membrane reactor for integrated gasification combined cycle (IGCC) applications. Once developed, the bench-scale zeolite membrane WGS reactor will be tested using raw synthesis gas (syngas) from a coal gasifier at the University of Kentucky-Integrated Coal/Biomass-to-Liquids (UK-CBTL) facility for H2 production with simultaneous CO2 separation. The project goal is to develop a bench-scale zeolite membrane reactor capable of producing about 2 kg of H2 per day (equivalent to a 2 kWth IGCC power plant), and to identify the operating conditions for a single-stage membrane reactor to produce a concentrated H2 stream with carbon monoxide conversion higher than 99.5 percent, CO2 capture greater than 90 percent, CO2 purity greater than 95 percent, and a cost of CO2 capture at less than $40/tonne of CO2. The performance and cost-effectiveness of the membrane reactor process will be evaluated for use in a 550-MWe coal-burning IGCC plant for CO2 capture.

Project Benefits

This will be the first effort to study zeolite membrane reactors for high-temperature chemical reaction and gas separation at this scale. The process design and techno-economic analysis, with the input of the experimental findings, will validate the effectiveness of the zeolite membrane reactor for WGS reaction and CO2/H2 separation. The results of this project will provide a foundation and guide for further scaling-up of the membrane reactor technology for pre-combustion CO2 capture at pilot-scale.
