Abstract: A method for operating a hydrogen production process with reduced incidents of hydrogen explosions by separating a hydrogen production step from a heat source by locating the hydrogen production step and the hydrogen heat source a substantial distance apart. Costs are not significantly increased by the substantial distance due to the fact that elevated temperatures are not required for the hydrogen generation step, and therefore heat loss is not an issue during the transportation of reaction compounds across the distances.

Abstract: The electroviscous suspension is based on a mixture of aqueous silica gel with silicone oil as the liquid phase to which a dispersant is added. The dispersant consists of amino functional or silicon-functional polysiloxanes having a molecular weight above 800. The concentration of the dispersant is from 1 to 30% by weight and preferably from 5 to 20% by weight, based on the silica gel particles. Electroviscous suspensions such as these are distinguished by the fact that they are highly compatible with elastomeric materials, non-sedimenting, non-inflammable and physiologically acceptable. In addition, they are heat- and freeze-resistant over a wide temperature range and are largely unaffected by temperature and pressure in their viscosity.
