Research subject of the thesis firstly are international treaties regulating marine resources management, including multilateral treaties in the field of law of the sea and sea environment protection relating to the mineral exploration and exploitation; bilateral and regional treaties and agreements on protection sea environment from pollutants of activities in continental shelf, treaties that establish joint exploitation areas.

Pyrolysis of activated sewage sludge was investigated under inert conditions in a fluidised-bed to study the effects of temperature and gas residence time on the product distribution and composition with an aim to maximise the oil yield.

In petroleum industry, it is desirable to produce lighter hydrocarbons such as gasoline, kerosene and gas–oil from unused heavy oils. Thus we have developed zirconia-supporting iron oxide catalysts View the MathML source to decompose petroleum residual oil (atmospheric distilled residual oil) with steam.

A new method for the synthesis of nanosized zeolites in organic solvents, such as formamide and toluene as crystallization medium instead of water, in the presence of organosilane has been developed. Organic solvents have a great impact on the synthesis of nanozeolites.

The velocity at which radiation travels (or propagates) through a medium is dependent on the medium itself When radiation travels through a medium and does not undergo a frequency change, it cannot be undergoing a permanent energy transfer However, radiation can still interact with the medium – Radiation, an EM field, polarizes the electron clouds of atoms in the medium – Polarization is a temporary deformation of the electron clouds

 IUPAC Definition: chromatography is a physical method of separation in which the components to be separated are distributed between two phases, one of which is stationary while the other moves in a definite direction  Stationary phase (SP): common name for the column packing material in any type of chromatography  Mobile phase (MP): liquid media that continuously flows through the column and carries the analytes  Analyte: the chemical species being investigated (detected and quantitatively measured) by an analytical method...

 Matched against a wide range of spectroscopic and chromatographic techniques, the techniques of electroanalytical chemistry find an important role for several reasons: – Electroanalytical methods are often specific for a particular oxidation state of an element – Electrochemical instrumentation is relatively inexpensive and can be miniaturized – Electroanalytical methods provide information about activities (rather than concentration)

 UV-Visible spectra can be interpreted to help determine molecular structure, but this is presently confined to the analysis of electron behavior in known compounds.  Information from other techniques (NMR, MS, IR) is usually far more useful for structural analysis  However, UV-Vis evidence should not be ignored!
