The coliquefaction of sulfur lignites and bituminous coals from Ukraine with polyethylene and polypropylene wastes was studied. The gas environment and the nature of catalysts were varied. The degree of conversion of the mixture and the yields of oils, asphaltenes, preasphaltenes, and volatile matter from the residues of coliquefaction were determined. It was hypothesized that oils were mainly formed from coals, especially in the mixtures of coals with polyethylene, whereas asphaltenes and preasphaltenes were formed from polyolefins.

The results of analysis of the causes of sizable discrepancy of data for longitudinal constituent H z obtained experimentally and numerically with the help of Microwave Studio program are given. The author also examined the method which enabled to reduce systematic inaccuracy considerably at the cost of taking into account the impact of uncoordinated line load.

Methods of a field of electrodynamic systems of the closed and opened types structure are observed, wich allows to define oscillation mode of resonators, to define amplitudes of different types of waves in waveguides, to estimate influence discontinuity on structure of an electromagnetic field, to count composition of space harmonics of a field in antennas mouth.

The method of a magnetic probe on the basis of a ferromagnetic resonance for research of structure of an electromagnetic field in electrodynamics system is considered. The substantiation of a method is lead on an example of electromagnetic wave H10 in a rectangular wave-guide. The experimental research of structure of an electromagnetic field of system a dielectric wave-guide on a metal basis is lead.

The authors have studied the joint liquefaction of sulfurous brown and long-flame coals of Ukraine and polyethylene and polypropylene at 430 °C and an initial pressure of up to 5.0 MPa. The gas phase consisted of H 2 , CO 2 , Ar or H 2 + CO 2 . The total conversion of the mixture and the volatile-matter yield from the residue of joint liquefaction after extraction of the products by alcohol-benzene were determined. The observed overall effect of synergism varied from 0 to 30%, depending on the type of polyolefin, coal and gas medium. Tetralin and H 2 inhibit the decomposition of polyethylene, which is why the individual effects of synergism may be either positive or negative.

The effect of the characteristics of sulfur brown and long-flame coals (Ukraine) on the evolution of hydrogen sulfide upon hydroliquefaction has been studied quantitatively. The amount of sulfur in H 2 S is given in absolute value (in mass units) and in relative value (in percent of total sulfur). In these two cases the pair linear correlation coefficients for the evolution of H 2 S with the parameters of a polylinear equation has opposite signs. The greatest effect is exhibited by the content of total and pyritic sulfur. The relationship between the evolution of H 2 S and organic sulfur is complicated and no relationship with the degree of conversion is observed.
