Effective heat transfer in a metal-hydride-based hydrogen separation process

摘要

this paper presents the results of experimental and analytical study of the thermal cycling absorption process (TCAP); which is a metal-hydride-based hydrogen separation system configured as a helical shell-and-tube heat exchanger. The column (tube side) is packed with Palladium deposited on kieselguhr (Pd/k). This packed column is thermally cycled by a hot and cold nitrogen gas on its exterior surface (shell side), while a stream of hydrogen mixed with other inert gases are passed through the packed column.
