The reasons for occurrence of photochemical smog in the cities of the Russian Federation have been studied, as well as the contribution of different sources to air pollution by formaldehyde, nitrogen oxides, ozone and other components. It has been concluded that there is a close interrelation between the concentrations of toxic substances in the troposphere.

The efficiency of woodwork fire protection using different flame retardants synthesized on the basis of composition of grade ОСА-1 has been evaluated. The process mechanism has been considered. Different acrylic dispersions have been analyzed with the aim of weather resistance enhancement. On the basis of the obtained data the guaranteed period of woodwork fire protection under conditions of open air storage has been predicted.

the flow diagram for ammonia recovery from the ammonia production off-gases has been proposed. This flow diagram introduction allows the decrease of natural gas consumption and elimination of ammonia containing water discharge into the sewerage system thus contributing to ecological situation improvement and reduction of the plant waste water management costs.

The advanced process of α-Al2O3.-based catalyst carriers production has been developed. Form and size optimization of the catalyst used for the methane conversion, contributed largely to the substantial improvement of its operational characteristics and considerable enhancement of economic performance and reliability of the tube heater for the methane steam conversion
