The Laboratory of heteroorganic petroleum compounds

Head of the Laboratory Prof. Raisa S. Min E-mail: lgosn@ipc.tsc.ru  Phone: 7 (3822) 492034; 491959 The field of the scientific interest: study of the composition, structure and properties of sulfur-containing crude oil compounds, chemistry of donor-acceptor interactions in non-aqueous multicomponent organic mixtures. Extensive studies to establish theoretical and applied bases of using metal halogenides to isolate oil components from complex organic mixtures and to apply theoretical concepts of complex formation in the practice of isolation and analysis of oil systems have been carried out under her direction.

Research fields:

Study of the composition, structure, properties, processes and mechanisms of the transformation of heteroatomic components of the crude oils and other hydrocarbon systems:

• The development of the methods to study heteroatomic components of the hydrocarbon systems;

• The study of the nature and mechanisms of the distribution of heteroatomic compounds in different hydrocarbon systems;

• The study of the pathways of the conversion of dispersed organic matter of recent and ancient sediments into the components of natural hydrocarbon systems;

• Revealing the general relationships between the chemical composition of heteroatomic components and the conditions of the occurrence and accumulation of crude oil pools;

• The study of the specific properties of oil components and their competent use.

Main results of basic research:

• The application of metal halogenides to isolate and separate the components of natural hydrocarbon systems was justified theoretically and practically: for the first time the extraction systems 'metal chloride-coordinating organic solvent', liquid adsorption chromatography of oil components with electron acceptors and coordination chromatography were successfully applied to isolate and concentrate heteroatomic crude oil components.

• General regularities of the distribution, composition and structure of native heteroatomic components with the chemical type of the crude oil and conditions of its occurrence in the Earth entrails have been established. 

• The features of the distribution and composition of heteroatomic crude oil components remaining in rocks of the reservoir developed by water flooding have been revealed. The contributions of nitrogen-, oxygen- and sulfur- containing compounds into the processes occurring at the oil-water and oil-rock boundaries have been determined.

Applied research:

The methods for the isolation of heteroatomic components from natural and technogenic feedstock have been developed. These methods are of importance when providing the scientific fundamentals for the technologies of extracting and manufacturing products of a desired composition to be purposefully used in different branches of the national economy, for example:

• the application of the modified concentrates of petroleum nitrogen-containing compounds as the catalysts of oxygen electroreduction, liquid-phase oxidation of hydrogen sulfide, selective heterogeneous reduction of nitrogen oxides;

• the application of the concentrates of aromatic and heteroatomic compounds in the processes of the flotation enrichment of coal  and polymetallic ores. Industrial tests showed a high efficiency of the oil concentrate (which is a new apolar collector) at the flotation of sulfide ores and coal slacks.

Leading staff:

 The field of the scientific interest: research of the nature and specific properties of nitrogen-containing oil compounds and other caustobioliths. A complex of methods allowing one to isolate bases, weak bases and neutral nitrogen compounds from complex organic mixtures, to study the relationships between the distribution, composition and structure of nitrogen-containing oil components differing by geologic and geochemical parameters of the reservoirs, to reveal the trends of the transformation of native nitrogen compounds under the conditions of catagenesis, biodegradation, production and processing of petroleum feedstock has been developed. The researches performed are of importance to solve fundamental problems of oil genesis, to establish the scientific fundamentals of the selection of the technologies for enhanced oil recovery in producing horizons and the ways of refining of the crude oil produced at the individual fields, to competently use the organic nitrogen compounds. 

 The field of the scientific interest: the study of the molecular composition of crude oil porphyrins and the methods for their isolation and analysis; the possibilities of their practical application; research of the distribution of different classes of crude oil compounds using the integral parts of oil dispersion systems (dispersed phase and dispersion medium). The investigation results allow one to extend the knowledge of the role, place and properties of different types of heteroatomic compounds in petroleum dispersed systems and to explain their behavior under reservoir conditions, at the processes of crude oil recovery, transport and refining.
