Combined Hydrogen Production and Storage via Reactive Ball Milling: Investigation of Carbon Structure for Hydrogen Capture

A combined hydrogen production and storage process was developed in which hydrogen was trapped within a coal-based structure, chemically modified via reactive ball milling. Low-temperature hydrogen evolution via TGA with mass spectroscopy (TG-MS), coupled with unusual Raman spectra, suggested both trapped molecular hydrogen and low-temperature dehydrogenation. The results of an investigation of the precursor coal structure in the resulting hydrogen evolution profiles were presented. This is an abstract of a paper presented at the 2006 AIChE National Meeting (San Francisco, CA 11/12-17/2006)
