System Analysis and Simulation of the Process of Destructive Hydrogenization of Deasphaltisate of Heavy Oil

The article presents a systematic analysis and simulation of the process of destructive hydrogenation of deasphalted oil. The process of thermoregeneration of spent zeolite and the surface - acid properties of CaA zeolite catalysts are also studied. It has been established that such patterns that allow predicting their influence and to regulate the quality of the hydrogenation obtained on one or another form of the catalyst obtained from the studied factors and catalysts. In addition, the obtained data can be used in the search for the optimal process modes of the process under consideration on the specific form of the catalyst.

Microwave Radiation Impact on Heavy Oil Upgrading from Carbonate Deposits in the Presence of Nano-Sized Magnetite

The present paper reports experiments on microwave heating of a carbonate oil-containing rock sample in the presence and absence of an iron-magnetite-based nanocatalyst. It has been shown that the used catalyst improves the processes of destructive hydrogenation of resins and asphaltenes compounds in the oil. The chemical reactions analysis demonstrated a decrease in asphaltenes content and in their molecular weight, which increases the filtration capacity of the oil fluid in the reservoir rock porous medium. Moreover, the content of non-extractable organic matter in the rock sample after experiments and after oil extraction was determined. It has been found that the absence of the catalyst causes the least increase in the content of non-extractable organic matter in the rock. This fact is related to the intensive processes of resinous-asphaltene compounds destruction especially at the level of peripheral groups which are the most condensed fraction, and hence leads to a decrease in their solubility in the organic medium and eases their adsorption on the mineral skeleton surface.

ABOUT DEVELOPMENT OF BIOFUEL TECHNOLOGIES

The article reviews the world experience of technological diversification in the fuel hydrocarbons production sphere. It is shown that the lost classical technologies, such as coals destructive hydrogenation and coals gasification, are reviving on a new technology basis. Some technological methods of receiving liquid fuels from biomass of various origin are analyzed. The technological schemes of production of biofuels of three generations using a natural vegetable material, various productions wastes, as well as biomass of water organisms as a carbon source are presented. The estimation was made of production outputs and costs of synthetic fuels (dimethyl ether, biodimethyl ether, biodiesel, gasoline and others). The conditions for development of biofuel technologies were formulated.
