Abstract

The first section presents the results of studies of the combustion process of oil on the surface of the water Karazhanbas. A synthetic adsorbent, stabilizing and supporting the process of ignition of self-propagation of the flame of oil on the water surface was proposed. The temperature characteristics of the flame and the oil and the adjacent water layer were determined. It is established that the minimum thickness of the oil, allowing the process to initiate and maintain combustion in the range 3-5 mm. The composition of the resulting structure of the soot and the residual mass of oil which is a substance having a good bitumoobraznoe adherence and strong adhesion, which allows him to collect with high efficiency mechanical.

In the second section of the paper presents experimental data on the use of crumb rubber used tires for the preparation of rubber binders (RBV). An analysis of physico-mechanical properties of the obtained RBV showed that the introduction of the bitumen in an amount of 15-25% crumb rubber with the size of fractions up to0.6 mmand processed used oil at a ratio of 1:1 and 3:2 can significantly improve the performance of road bitumen. Crumb rubber in the binder acts as a polymer component particles carried out dispersion-elastic asphalt reinforcement.

The third section examined the conversion dependence on methane and carbon dioxide output and target values of the reaction products - hydrogen and carbon monoxide on the temperature and time of catalysis. Samples of the catalysts were synthesized by low-percentage (less than 1% by weight) by the SC. At the maximum catalyst activity reached a high yield of synthesis gas 32% H2 and 46% CO and CH4 conversion is 30%, CO2 - 80%. SEM and TEM study of the surface of the fiberglass sample showed that the active component consists of individual particle size of 10 nm, forming an oxide film.
