| EDITORSHIP GREETING TO READERS OF THE FIRST ISSUE B. P. Toumanian STATE AND PROBLEMS OF RUSSIA OIL REFINING INDUSTRY B. P. Toumanian OPPORTUNITIES OF EXTRACTION ENGINEERING IN PRODUCTION OF NON-POLLUTING MOTOR FUELS A. A. Gaile, V. Е. Somov, L. V. Semenov, A. A. Zuikov, G. D. Zalishchevskii, О. М. Varshavskii, E. A. Kaifadzhyan, and L. L. Koldobskaya At hydrotreatment of fuel, only heteroatomic compounds are removed efficiently whereas arenas are hydrogenated to an insignificant degree. As alternative to hydrogenation processes, we have developed extraction technologies. Considered in this article is extraction treatment technology, various extraction agents are analyzed, and the results of extraction treatment of straight-run and hydrotreated cuts are given. MAXIMIZATION OF INCOME FROM PETROLEUM PRODUCT SALE TAKING INTO ACCOUNT MARKETING OUTLETS I. V. Rjazanov and V. A. Mironova PERSPECTIVE DIRECTIONS IN CHEMICAL TREARMENT OF METHANOL S.N.Antonyuk, E.V.Egorova An opportunity to match the processes of methanol decomposition with production of hydrogen-containing gas (Н2 + СО or Н2 + СО2), methyl formate, dimethyl ether and catalytic decarbonylation of methyl formate for production of carbon monoxide has been studied. Various variants of the reactor loading distinguished in catalyst system sequence arrangements have been investigated. A NEW CONCEPT FOR STUDYING AND DEVELOPING OIL AND GAS POOLS (FRACTAL GEOFLUIDODYNAMICS OF PETROLEUM SYSTEMS) N.P. Zapivalov, G.I.Smirnov, V.I.kharitonov, I.P.Popov, O.M.Garipov A new method is proposed for fractal analysis of geodynamics of oil and gas fields being developed under conditions of technogenic actions. An interrelation is studied between fractal structure of multiphase medium modeling reservoir and features of propagating seismic waves in the above medium. Optimal regimes of development (additional development) and methods of possible intensity increasing for each specific object are needed. Besides, we have to provide rehabilitation periods for the fields and pools with exhausted "fractured" reserves. A major part of "damaged" petroleum saturated fields should be put out of production (relaxation period) for achieving stable fluidodynamic equilibrium of the system. This task has to be solved for each pool individually on the base of fluid dynamic monitoring. Such is a way to increase extractable active reserves even 2-3 times. PUMPING OF DIESEL FUEL INJECTED WITH THE POLYMER ADDITIVE NECADD-547 Chelintsev, E. Chelintseva, I. Eroshkina., H. Harjuhahto, V. Maron, A. Prokhorov. DISPUTED INSTABILITY OF THE PRICE ON PETROLEUM AND WAYS OF ITS STABILIZATION. V. I.Maron, M.N.Fridman KINETIC PECULIARITIES OF SYNTHESIS OF ADAMANTAN-CONTAINING POLYAMIDOACIDS AND POLYIMIDES I. A Novakov, B. S.Orlinson, G. E. Zaikov, V. G.Zaikov SOLID POLYMERIC SULFOACIDS AS CATALYSTS OF ALKYLATION'S PROCESSE V. A.Zavorotny, J. A.Topoljuk, K. D.Korenev, D. K.Korenev, O.I.Bentzianov. It has represented a review of publications concerning of use of solid polymeric sulfogroups (SPS) based on copolymers of styrene and divinylbenzene and perfluorated copolymers as catalysts of alkylations of alcohols, phenol, isobutane, benzene and it's homologies with different olefins. It has shown the results of indicates catalytic process depend on the structure of polymeric matrice and the distribution of active sulfogroups in granules of polymers. A most effective catalysts are less cross-linked SPS for alkylation of polar compounds (alcohols, phenol). These catalysts have large-sized pores in its polymeric granules. More cross-linked SPS having the developed surface of pores are preferred for alkylation of less polar compounds (aromatic hydrocarbons etc). To alkylate isobutane it needs the SPS having the superacid sulfogroups. It could be reached by use the perfluorinated polymer matrice or by modification of sulfogroups with acidic protonoaceptor substances. THERMOCATALYTIC PROCESSES FOR DEEPENING OIL REFINING AND IMPROVING MOTOR FUEL QUALITY E.F.Kaminsky, T.Kh.Melik-Akhnazarov, V.M.Kurganov, L.N.Osipov, V.A.Khavkin. While accounting for 85% to 95% in the developed countries of Europe and the Americas, the yield outcome from oil refining in Russia is only 63% to 65%. The broad implementation of secondary destructive oil refining processes, such as catalytic cracking, hydrocracking, thermal processes*, is required here. Motor gasolines and diesel fuels should be in strict compliance with the new environmental requirements. It is important for the manufacture of gasoline to phase out lead and substitute A-76 and A-80 with a high octane unleaded fuel. The sulfur content of diesel fuels, when in manufacture, should be brought down to 0.2% wt. Schemes based on separation processing of vacuum distillates and petroleum residues are promising. |
