The direct conversion of crude oil to light olefins is considered one the cheapest and most reliable sources of petrochemical primary feedstocks. Unlike in the past when refineries operated to produce mainly transportation fuels, such as gasoline and…
Petroleum refinery has been developed for production of transportation fuel with light alkenes and benzene, toluene, ethylbenzene, and xylenes (abbreviated BTEX), but global market demands are shifting to chemicals produced from light alkenes and…
Scope: This International Standard specifies a method for the determination of the bromine number of the following materials: a) petroleum distillates that are substantially free of material lighter than 2-methylpropane, and that have 90 %(V/V) (i.e.…
1 Scope This document specifies a test method for the determination of the content of mono-aromatic, di-aromatic and tri+-aromatic hydrocarbons in diesel fuels, paraffinic diesel fuels and petroleum distillates. This document defines two procedures,…
1 Scope This document specifies a fluorescent indicator adsorption method for the determination of hydrocarbon types over the concentration ranges from 5 % (V/V) to 99 % (V/V) aromatic hydrocarbons, 0,3 % (V/V) to 55 % (V/V) olefins, and 1 % (V/V) to…
The direct conversion of crude oil to light olefins is considered one the cheapest and most reliable sources of petrochemical primary feedstocks. Unlike in the past when refineries operated to produce mainly transportation fuels, such as gasoline and…
Natural gas liquids (NGLs) in shale gas are the predominant feedstock for light olefin production. Conventionally, NGLs are separated from CH4 and then fractionated into individual components before these components go through either steam cracking…
Based on the theory that viscous crude oil can form stable two-phase oil-water interfacial molecular membrane with surfactant, the oil-water interfacial activity and viscosity reduction of oil-water interface of viscous crude oil were studied for the…
A combination of multi-dimensional supercritical fluid chromatography and field ionization time-of-flight mass spectrometry (SFC FI-TOF MS) is developed for the detailed analysis of olefins and other hydrocarbon types in total petroleum liquid…
In this work, the fouling behaviour of thermally processed bitumen products obtained by visbreaking was studied. The feedstock was prepared by blending raw oil sands bitumen with 15 vol% hydrotreated light oil (HLO). The visbreaking products obtained…
The features of cracking catalysts produced by aluminosilicate technology are described. Approaches to designing cracking catalysts for processing various types of materials (light, heavy, mixed) are shown. The main methods for modifying components…
Bio-oils after hydrotreatment can still contain significant amount of phenols and cyclic olefins as the products of an incomplete deoxygenation. The removal of these compounds would be necessary to produce suitable components for automotive fuels.…
