Diversification grounded primary sources of raw materials for synthetic liquid hydrocarbons through the intermediate step of producing syngas from natural gas to the solid fossil fuel for example shale and use existing processes currently processing.
Gasification Process shale long been known, but the problem of obtaining a gas suitable as a feedstock for the Fischer-Tropsch process is a new trend in the processing of shale.
The analysis of the results of many years of operating experience of existing processes in order to identify those among them who are already without modification or with minor modifications can be used to obtain raw materials of the Fischer-Tropsch process. This paper analyzes the processes of thermal processing of various raw objects used for further conversion into fuel hydrocarbons. The subjects were studied coal, peat, shale. In each case was of interest syngas conversion which results in C5 and higher hydrocarbons.
Found that the most appropriate process is pyrolysis of oil shale in chamber furnaces. Achieved a maximum yield of gas per unit mass of material. Content ratio of hydrogen to carbon monoxide is close to 2, which is a criterion for the suitability of the product gas for Fischer-Tropsch process.
Keywords: diversification raw, Fischer-Tropsch process, oil shale, ratio of hydrogen to carbon monoxide, syngas, furnace chamber.

ABSTRACT
Ways of improving the quality of gas supplied to the processing by splitting the gas-liquid flow in order to effectively discharge the hydrocarbon condensate. Presents options for the use of the hydrocarbon condensate. The most interesting option - Preparing for the hydrocarbon condensate preparation unit and the direction of his or mixes with a broad fraction of hydrocarbons, or involvement in processing on the installation of gas processing. A positive aspect of this embodiment is the use of the hydrocarbon condensate without loss of valuable hydrocarbons C3-C10.
Stages of preparation the hydrocarbon condensate. It is important to determine the composition and quantity of impurities and negative the hydrocarbon condensate, because these data are the determining factors in choosing the necessary stages of preparation the hydrocarbon condensate.
The comparison of the quality of commercial grade A broad fraction of hydrocarbons prepared hydrocarbon condensate and the total combined flow after mixing. It is shown that the mixing certain amount of hydrocarbon condensate with marketable broad fraction of hydrocarbons, the quality of the total flow meets the technical requirements for broad fraction of hydrocarbons.
Keywords: hydrocarbon condensate, cleaning unit, drying unit.

ABSTRACTS
Stages of the study of various compounds to increase the octane number of gasoline, and several theories regarding the phenomenon of detonation are presented in the article. In the no empirical approximations of RHF/6-31G (p, d), MP2/6-31G (p, d), in the gas-phase there were investigated geometric and electronic structure and standard enthalpy of formation of several paraffins, isoparaffins and ethers. It is shown the influence of centralization, methyl groups of isoparaffins and elongation of alkyl chain, the oxygen atom of ethers to the change of the structural characteristics and octane number.
Keywords: ethers; paraffins; isoparaffins; constrained Hartree-Fock method; dipole moment; geometric and electronic structure; perturbation theory Moller-Plesset; octane number; detonation.

ABSTRACT
The rate of corrosion of carbon and low alloy steels affect the carbon dioxide concentration in water, pressure and temperature process. In assessing the impact velocity on the corrosion rate shows the need to consider the specific work environments, in particular the specific carbon acid corrosion. The quantitative indicators of changes in corrosion rate, depending on the speed of the fluid in the pipe. To improve reliability of operation is recommended to carry out lines define the rate of corrosion in corrosive cell simultaneously by two methods — a gravimetric (weight change on metallic samples), and, for example, electrochemical (linear polarization resistance method LPR).
Keywords: carbon acid corrosion, pipeline, corrosion cell, gravimetric method, electrochemical method.
