Abstract
Bloated minerals previously used as aggregates for light-weight concrete are here fragmented, wetted, and intermixed with particulate chemical reactants or catalysts, to serve as inert carriers therefor in industrial processes. One use is in the deep-bed flow-through process of reacting and removing hydrogen sulfide as contained in natural gas.
