Undesirable side effects of antiwear additives for diesel fuels
Keywords: diesel fuel, side effects of additives.
GOST R 52368 and GOST 305 diesel fuels (with 0,05% sulphur content) cannot be produced without antiwear additives being added. At the refineries were being used until recent time foreign additives permitted for application and included into the Safety List, so called no-harm sheet. Domestic developers now get down to additives manufacture.
Antiwear additives are produced on the basis of fatty acids which could render negative side effects on operational properties of diesel fuel. Therefore the estimation of additives is performed with use of special DGMK 531-1 tests and additional methods, investigating carburization of injectors, interaction with elastomers, oxidative stability etc.
In order to avoid unsatisfactory claims, domestic additives are necessary to be proved for absence of undesirable side effects at their use in diesel fuels.

Application experience of sulphurising agent DMDS YANUO for hydrotreatment catalysts
Keywords: hydrotreatment catalysts, sulphurising agents, dimethyldisulphide.
Refiners concerning hydrotreating catalysts sulfiding can use data of different sulfur-containing substances. RADOIL group of companies have made pilot tests to compare sulfiding of commercial hydrotreating catalyst by DMDS, manufactured at HEBEI YANUO and in European Union. It has been determined that DMDS manufactured by HEBEI YANUO Chemical Industry Co., Ltd. is not worse than a European counterpart.

Estimating tribochemical stability of liquid lubricants in rolling friction zone by activation energy
Keywords: lubricants, working capacity, rolling bearings, one-time filling, friction parametres, contact tension, speed factor, activation energy, tribochemical transformations, atmosphere, vacuum.
Results of modelling the influence of friction parametres (contact tension and speed factor) upon activation energy of tribochemical wear of lubricants in a rolling friction zone with one-time filling are given. For activation energy the calculation data is used, concerning limited working capacity of lubricants in vacuum and in air medium, obtained with help of a five-ball friction machine. Liquid bases of high-temperature and special greases are taken as lubricants. On the basis of resulted model the possibilities of lubricants application in various operational conditions are observed.

Alternative alcohol fuels – once again
Keywords: fuel ethanol, motor gasoline, fuel Е 85.
A well-reasoned substantiation of necessity of fuel ethanol manufacture development in Russia is given. As an example could serve the experience of various countries of the world, where bioethanol use at motor gasoline production becomes obligatory, as it promotes decrease in СО2-emission into atmosphere with vehicle exhausts.
