Discovery the Phenomenon and Novelty of the Way • • • The phenomenon of radiation-thermal activation the hard phase reactions in non-organic systems opened in 1970 -80 th by the group of the scientists from Leningrad, Novosibirsk, Alma-Ata and Yerevan allows to intensify cardinally and to make much more friendly to the environment the production of many energy-intensive, high temperature materials. The beam of high energy (1, 5 – 2 Me. V) electrons transfers the energy to all volume of irradiated matter simultaneously excluding heat conduction factor that limits process speed. Beside purely thermal effect of speed burning the phenomenon of radiation-thermal activation takes the place too. RT-activation applying to clinker formation means: - temperature reduction of physical-chemical transformations on 150 -200°С; - completion of Portland cement clinker formation from dry raw mix by the power of absorbed dose 200 -400 W/g during 5 -15 s (in rotary kilns it continues more than hour). The fundamentals of radiation technology of cement clinker have been developed in 1970 -1980 th by the Institute Giprocement (Leningrad) in the cooperation with NIIEFA (Leningrad) and Institute of Nuclear Physic (Novosibirsk). The Building Materials Industry Ministry of USSR through its special program realized the financing of these works.

Radiation-thermal apparatus A number of constructions of radiationthermal apparatus (RTA) for the clinker synthesis in an electrons beam have been tested. Shaft type for RTA has been proved as most effective. It provides the translocation material particles from the surface into the depth of radiation zone: electrons beam and materials flow are coaxial. As a result we receive the product with uniform properties by minimal energy consumption.

From Technology Fundamentals to Semi-industrial Realization Main advantages of the technology consist in the exclusion technological use of the hydrocarbon fuel and in cardinal reduce of harmful gas and dust emissions in the atmosphere. Revival of the development needs the investment of $4. 5 -5. 0 Mln. It can be expect with big probability the interest in RT in the countries where hydrocarbon power does not play determining role in national total power. China also displayed the interest to RT. The global problem is the struggle against greenhouse effect. The last one is obliged to constantly growing techno-gene allocations of carbon dioxide. RT excludes fuel carbon dioxide. And high concentrated technological СО 2 can be used in principle as favorable product (without emission in the atmosphere). 2013 – the development of demo pilot line design, order on the equipment, montage and launching the line, the development of the program and experience procedures with the materials high temperature synthesis of which does not allow reduction-oxidation medium (exclusive white cement, titanates, tungsten carbide, exclusive valuable alloys, for example - Ti-Ta-Nb, and so on). 2014 –carrying out the experimental series along the developed program, their data processing and the development of industrial lines designs.

The Market • Market segments on which the project products are orientated: building materials, building, electronics, nuclear power industry. • Key distinctions of proposed technology: ecological purity, high products quality, exclusion the hydrocarbons from their production.

Possible Economic Effect on Pilot Line Stage • • Gas emissions consist of concentrated technological СО 2 , “greenhouse” СО 2 emissions reduce themselves in 1, 5 times. The cost of one СО 2 emission ton is established to-day in EU on the level of 30 еurо. So each ton of the clinker received by RT way gives 10 euro of income. The cost of one compressed СО 2 ton consists now of 100 еurо. It means that organizing СО 2 take-off on pilot line, can man to receive addition income not less than 400000 euro/year. The cost of super white cement consists to-day of $250/t. Therefore pilot line, by year productivity of 4000 t, could bring income of $1, 0 Mln. , if it will orientate on the receiving only this product. In this case the viability of pilot line will not exceed 5 years. The cost of alkalic metals titanates consists in average not less than $900/t. In this case, by the orientation on the receiving titanates, the viability of pilot line will not exceed 1, 4 years.
