In
order to minimize our dependence on foreign fossil fuels and improve our
environment, the DOE has embarked on the development of hydrogen-based power
production. As part of this
development, it will be necessary to separate hydrogen from the synthesis gas
derived from coal gasification, an operation requiring high-temperature
membranes. This project will develop
chemically durable, SiC-based hydrogen separation membranes with permeance and
selectivity performance suitable for the purification of hydrogen from synthesis
gas derived from coal gasification. In
Phase I, the SiC-based hydrogen separation membranes will be developed using
novel chemistries and fabrication approaches.
These membranes will be analyzed for permeability and selectivity of
hydrogen, and for durability in a high-temperature CO2/H2O
environment.
Commercial
Applications and Other Benefits as described by the awardee:
The membranes should find use in the purification of hydrogen from
synthesis gas. The hydrogen itself
would be used in fuel cell power production, fuel desulphurization, and
chemicals production by hydrogenation reactions.
The membranes also may be used in catalytic membrane reactors for
dehydrogenation and water gas shift reactors.
