The study of a process for the low cost production of silane included laboratory investigations of the kinetics of the redistribution of dichlorosilane and trichlorosilane vapor over a tertiary amine ion exchange resin catalyst. The hydrogenation of SiCl/sub 4/ to form HSiCl/sub 3/ and the direct synthesis of H/sub 2/SiCl/sub 2/ from HCl gas and metallurigical silicon metal were also studied. The purification of SiH/sub 4/ using activated carbon adsorbent was studied along with a process for storing SiH/sub 4/ adsorbed on carbon. The latter makes possible a higher volumetric efficiency than the current practice of compressed gas storage. The mini-plant designed to produce ten pounds per day of SiH/sub 4/ is nearly complete, a detailed description of the unit and its essential design features are given.
