Definitions

  • This invention relates to a material for and method of effecting the decomposition/dissociation of water to form hydrogen.
  • the water is reacted with an amalgam of sodium, aluminum and mercury to form hydrogen and a metallic hydroxide believed to be Na 3 AL(OH) g .
  • the material found as suitable for generation of hydrogen from water without spontaneous combus ⁇ tion of the resultant evolved hydrogen comprises an amalgam of (1) an alkali metal such as lithium, sodium, potassium, cesium or combinations thereof, (2) aluminum and (3) mercury.
  • the particle size of the sodium and aluminum is such as to facilitate formation of an amalgam.
  • the amalgam has been prepared utilizing sodium of about 1/4 inch diameter and aluminu within the range of about 10 to about 100 mesh.
  • the particle si of either the alkali metal or the aluminum is not critical for proper mixing or blending, but the presence of impurities advers effect such mixing.
  • the weight ratio of alkali- metal to mercury may be fro about 1:100 to about 100:1 and the weight ratio of alkali metal to aluminum may be from about 1:100 to 100:1.
  • the weight ratio of alkali metal to mercury is from about 3:1 to about 1:4.5 and the weight ratio of alkali metal to aluminum is from about 1:4 to about 3:1.
  • the water reacts with the alkal metal, e.g., sodium, and the aluminum liberating hydrogen to form Na,AL(0H) fi .
  • the reaction of the water with the amalgam is substantially different from the reaction of the alkali metal component of the amalgam with water.
  • the heat generated by reaction of equivalent amounts of alkali metal in the form of th amalgam is. substantially less than where the alkali metal alone ' is reacted with water. Accordingly, spontaneous combustion of the hydrogen in an oxidizing environment as well as the formatio of a highly stable sodium product is avoided where the amalgam o the invention is employed in place of the alkali metal alone.
  • the process may be depicted as follows:
  • amalgam of sodium, aluminum and mercury is prepare utilizing any known procedure for amalgamation with the added important proviso that an inert atmosphere be maintained during amalgamation.
  • Amalgamation may be facilitated by utilization of an elevated temperature preferably around 200° C. — 10° C.
  • the amalgam is preferably maintained at this elevated temperature fo about 10 minutes where 100 grams are being processed and the tim is extended about a minute for each additional 100 gram aliquot.
  • the resulting amalgam is cooled, generally to room temperature, utilizing an inert atmosphere.
  • an inert atmosphere for this purpose, either helium or nitrogen are satisfactory. Cooling is preferably effected in a dessicator to insure that no water contacts the amalgam.
  • the amalgam solidifies and may be contacted with water by submersion, by spraying the water thereupon, by impinging water in the form of steam thereon or in any other manner.
  • 35.144 parts by weight of sodium, 13.749 parts by weig of aluminum and 51.107 parts by weight of mercury are formed into an amalgam under an inert atmosphere of nitrogen at an elevated temperature of 200° C. in graphite crucible.
  • the resulting amalgam is cooled to room temperature in a dessicator under an inert nitrogen atmosphere. Thereafter, the amalgam is formed which is a solid but which will liquefy upon agitation.
  • amalgam should be prepared in an inert gas atmosphere to prevent premature hydrox ⁇ ide formation.
  • the amalgam is placed in a suitable container with one surface thereof exposed. Water is sprayed upon the exposed surface or alternatively the exposed surface may be covered entirely with a layer of water. It is necessary that the amalga be placed within a container because in the course of contact of the amalgam with water the heat generated during the course of hydrogen generation transforms the amalgam to liquid form. The amalgam regardless of how it is contacted with water will not cause an explosion.
