Using of the fuel combustion catalysis of metal and semiconductor type on the base of d- and s-elements, make it possible to resolve efficiently the power supply and environmental problems. Various methods of preparation are applied of both compact and disperce catalysts. Using of industrial wastes to for these scopes is of certain interest (Pat. MD #1880). Among the numerous industrial wastes, the most available for the catalysts preparation are plating sludge and used technological solutions. It was also possible to use the glue winery wastes, containing ferroferricyanides formed as a result of wine-materilas de-metallization (Pat. MD #2178 and #2268). To implement these processes, there was a need to elaborate not only the technologies, but also the flow sheets. One of the proposed technologies implied the preparation of skeleton-type metal catalysts obtaining on the supports, with high catalytical activity. For this scope the methods of chemical reduction of polymetals were applied (Pat. MD #481 and #705), containing non-metal inclusions (boron, phosphorus) which can be readily aluminized and leached. An advantage of this method is the possibility to apply the catalytic layers on both metal and non-metal support (ceramics). The other proposed method included the preparation of stabilized air-mazut emulsions Pat. MD #1884), containing the catalytically active components, and their combustion. The efficiency of their burning is reached by the combination of the following procsses: explosion-type evaporation and dispercing of water suspension, thermo-catalytical destruction of water molecules with the formation of free radicals and synthesis-gas. These features would improve not only the performance of burning, but also the environmental indicators, decreasing the emissions of nitrogen and sulphur. These processes are initiated with the electrosparkle discharges, ocuring in the rotating electromagnetic field (Pat. MD #2178). In principal new and interesting turned out to be the proposal on thermo-magnetic enriching of air with oxygen, directed at the fuel combustion (Pat. MD #2615). In this method the effect of abnormally high magnetic acceptibility of oxygen in magnetic filed is used, which permits to rise the operation efficiency of combustion engines and to reduce the toxic transport emissions (Pat. Appl. MD #2004-0023). The third research direction is dealing with the enhancing of air emissions catalytical treatment efficiency under the hydrodynamic conditions (Pat. MD #1654), and also under the magnetic fluidization of oxide catalysts (Pat. MD #1648) and the metal ones in the poly-gradient and revolving electromagnetic fields. The toxic ingredients in chimney emissions are subjected thus to the oxidativereduction destruction and subsequently are neutralized with the ammonia. Ammonia salts are formed which can be used as mineral fertilizers (Pat. MD #2522). Once they are neuntralized with the quicklime, the precipitates are yielded which can be readily utilized in glass boiling (Pat. Appl. MD #2004-0211). To purify the fume emissions, containing disperse pollutants, the new design of modernized sack-filter is proposed (Pat. MD #1669). In this way, the new technical solutions proposed by us lately, make it possible to resolve power supply and environmental problems.
