On the issue of conducting the conversion of fractional compositions of petroleum products and oils in order to predict the yields in volumetric and mass percentage
Keywords: Model of compositions conversion, volumetric and mass percentages, cubic splines, experimental and calculated data, TBP, GOST 2177, the adequacy of the model.
Abstract. Algorithm is developed and the program is implemented in MS Excel environment, which solved the problems of petroleum products and oil and gas condensate feedstock compositions conversion as per TBP into the compositions according to GOST 2177 and vice versa. It allows using minimum initial information
on fractions outputs with known boiling point obtained experimentally in the laboratory for converting. If one knows a few points with fractions end points, it is possible to extend them using the proposed method. Comparison of experimental and calculated data for the conversion of motor fuels was carried out (as per TBP compositions into the compositions according to GOST 2177) and oil and gas condensate feedstock (vice
versa). The proposed model was adequate to experimental data with a mean relative error of less than 1%. It can be used to obtain the calculated distillations (in volume or mass percent) for fractions with different boiling range.

Influence of solid additives during sulfurous tar coking on the quality of products obtained
Keywords: petroleum coke, tar, coking, solid additives, sulfur content in coke, coking distillates.
Abstract. By means of the delayed coking pilot plant GUP INKhP RB conducted studies on tar coking using solid additives: coke breeze, slate powder and lignite. The experiments have shown that a significant reduction in the sulfur content of the coke is observed during tar coking with slate powder, and no significant changes in the quality characteristics of the distillate fractions have been identified.

Process of joint processing of ammonia and hydrogen sulfide containing gases with high sulfur recovery rate
Keywords: hydrogen sulfide, ammonia, sulfur production, Claus method, optimization.
Abstract. The growth of environmental requirements to industrial facilities on process emissions makes it actual the task of increasing the degree of sulfur recovery during the sulfur-containing feed processing. However, the existing hydrogen sulfide processing technologies do not work in optimal conditions, without providing the highest possible degrees of sulfur recovery. The presence of ammonia in the process hydrogen
sulfide gases creates certain difficulties in the process management. This paper shows the directions of optimizing the individual stages of the existing sulfur production process by Claus method, the result of which was the development of the process with a degree of sulfur recovery of more than 99% with the presence of ammonia in the process gas.

Abstract. Studies of regeneration by supercritical carbon dioxide and with the addition of the chlorinated compound (CCl4) of superacid catalysts based on mixed heteropoly acids applied onto acid activated montmorillonite were conducted. A comparison of the effectiveness of the catalyst performance in the oligomerization process after five «reaction-regeneration» cycles was conducted.

From the experience of the development of regional standards for road bitumen and polymer bitumen binders, for asphalt and polymer asphalt concrete
Keywords: road bitumen, road construction, non-oxidized bitumen, modified bitumen, PBB polymer asphalt concrete.
Abstract. New standards for bitumen and polymer bitumen materials, asphalt and polymer asphalt concretes do not consider current operating conditions of road surfaces. Specific examples of the detected inconsistencies between the standards for organic binders and asphalt concrete are shown. The scheme of the regional experiment, which aims to bring order to the road construction in one particular region of Russia is presented. New draft standards for organic binders and a number of suggestions to improve the performance of asphalt concretes are presented. The necessity to develop the asphalt concrete standards, along with standards
for binders based on new organic binders is justified. Examples of the first practical tests of new materials are shown.
