The effect of different schemes for loading the catalyst into the reactor for hydrotreating of the mercaptan—containing IBP—350°C cut of Astrakhan' gas condensate on the degree of the increase in the pressure differential in the reactor is investigated. The basic causes of crust formation on...
The water solubility and thermal stability of sulfoxide concentrates obtained by oxidation of Arlan Crude Oil Diesel fuel cuts with hydrogen peroxide followed by separation of sulfuric acid were investigated. A dependence was found between the cutpoints and water solubility of the sulfoxide...
Heat treatment is a common method of improving the properties of heavy crude oils and petroleum products. Measurements showed for the first time that after heat treatment at 28—40°C, the rheological parameters of petroleum systems become much worse. The results obtained are important for...
Exhaust gas (EG) smoke from internal combustion engines (ICE) is one of the basic negative environmental factors of means of transportation and, other machines and mechanisms. This is primarily due to the high concentration of carcinogens formed in burning fuel in the engine and soot particles...
The possibility of eliminating the shortage of binder for production of carbon adsorbents from crude oil cuts was demonstrated previously (1). However, coal as a stock base prevents improving the sorption characteristics and expanding the assortment of adsorbents. Petroleum residues are also of...
The capacity of pentasils to aromatize C 2 — C 12 hydrocarbons is determined by a number of factors, in particular, the SiO 2 :Al 2 O 2 ratio in the zeolite, the degree of decationization, the presence of a modifying additive and its state in the reaction conditions, the amount of zeolite in...
Describing the kinetics of formation of non—Newtonian, rheologically complex media such as dispersions of polymers in petroleum residues is of great interest since this would provide information on the behavior of the system in different stages of fabrication of a composite material with...
The prohibition on use of tetraethyllead and the requirement of significantly reducing the aromatic hydrocarbon content make it necessary to incorporate large quantities of branched C 5 —C 6 paraffins in gasolines. These compounds can be obtained by isomerization of the corresponding linear...
