Alkali Metal Catalyzed Water Vapour Gasification of Carbon Using Mineral Catalyst Raw Materials

Beryllium oxide shows a limited reversible solubility in molten alkali-metal hydroxides only when dissolved water vapour is present. The reaction taking place has been studied in detail. The results obtained are consistent with the reversible formation of the beryllate ion [Be(OH)4]2- as the major product, according to the overall equation BeO(solid) + H2O(dissolved) + 2OH- ↔ [Be(OH)4]2-(dissolved) The enthalpy of the reaction has been calculated to be 4.8 kcal/mole over the temperature range 240-510�.

Mechanical Stirring

The results of studies of the reduction of alkali metal oxides in nepheline sludge are presented. The alkali-containing phase is sodium hydroaluminosilicate. The methodology of the experimental studies involved the preparation of a water suspension with a given ratio W:T, mechanical stirring, heating, aging and separation of the pulp on a vacuum filter. A technology has been developed to reduce the alkali content by 21% of the initial amount of alkali, which has increased the melting temperature by 310 ° C. The obtained results are the basis for the design of a pilot plant and the development of refractory heat-insulating materials with the replacement of expensive mineral raw materials with non-deficient man-made waste.

Preheating Temperature

Aluminum dross is presented as a potential material to form AlON using thermite reaction. The commercial MgAl powder, active carbon, and titania were prepared to make a chemical furnace (self-propagation combustion). The preheating temperature of 300 is enough to intitate ignition of the mixture as fuel and oxidizer. The addition of Y2O3 (1wt. %) is effective to enhance solid solution products between Al2O3 and AlN in the Aluminum dross. The level of contamination like an alkali metal oxide in the Aluminum dross was reduced highly by the heat from chemical furnace.
