n–d–M Methods of structural and group analysis of many products from crude oils and coals are critically examined. Equations are proposed for the structural group analysis of heavy crude oil resid and brown coal hydrogenates. It is shown that the structural group compositions of the products...
Sorption of motor fuel vapors by sorbents of different natures is described. The goal is to select the optimum sorbent to prevent fuel losses from evaporation during storage. Industrial medium–pore silica gels KSS–3 and KSS–4 are effective in recovery. Industrial zeolite NaX and SKT...
The characteristics of modeling of distillation of products that nonmonotonically distill in gradual distillation according to the method in GOST 2177‐82 (ASTM D86), mixed products in particular ‐ naphthas with addition of alcohols, ethers, and aromatic compounds, are described.
Type 1A/1M, GK–3, and G–43–107 cat crackers (CC) with pulverized catalysts are important in the oil refining industry. A special feature of these cat crackers is the presence of parts subject to significant abrasive wear at 400–700°C. In the last ten years, CC have been actively revamped...
Technology was developed for manufacturing special asphalt varnish with improved properties directly in the stage of oxidation of the feedstock by addition of modifiers. Oxidation is intensified and the yield of target product increases. The asphalt obtained satisfies the requirements in GOST...
In conditions of ordinary use, the lifetime of lube oils is a function of their properties and the technical state and conditions of use of the machine. In severe conditions of use, the oil can exhaust its lifetime and consequently lose its work capacity long before the factory–recommended time...
Sources of environmental pollution in packaging, shipping, and use of hard asphalts are examined. Most environmental problems have been solved by changing to polyethylene film containers. There is almost no monitoring of air pollution by benz–α–pyrene, contained in the vapors liberated in...
An important problem in the oil-refining industry is exhaustive refining of hydrocarbon feedstock into high–octane components of motor fuels using destructive catalytic processes. This is due to the limited resources of crude oil and gas feedstock, the increasing demand for automotive...
Technology for manufacture of aviation oils based on oligomerization of C 8 –C 10 and C 6 –C 12 higher α–olefincuts, cutation, and hydrogenation is described. The oils obtained have good thermooxidative stability and viscosity–temperature and low–temperature properties.
Most of the country's oil units are primarily oriented toward production of lube oils. The by–products formed are used as components of furnace residual fuel oil. Even the slack wax obtained in dewaxing of selectively refined raffinates goes into furnace residual fuel oil. The slack wax...
