Modeling of effective environment neutralization systems of harmful gases by metal-oxide catalests of photochemical decomposition

TiO₂ nanoparticles in crystal updating anatase show excellent photocatalytic properties guaranteeing ability to destruction of various harmful substances. In the present paper results of the mathematical modeling of a cloud the nanosizes catalyst particles formation and evolution process are presented at their formation by three technical systems: (1) as a operation result of solid propellant gas generator with charges specially picked up pyrotechnic titan substance mixtures in which combustion products contains the high percent of particles TiO₂ of metastable crystal updating; (2) at explosion of special explosives on the basis of urea´s nitro-compounds and metal salts; (3) at dispersion of the ready catalyst by explosive way and / or cocurrent jet of gasgenerator combustion products. In the last case explosive formation of nanocatalysts particles cloud the variant of charges special system explosion of explosives is considered, the chemical gasdynamics process is analyzed.
