WebKeywords: bitumen; bitumen fractional composition; crude oil; chromatography. 1. Introduction Bitumen is a byproduct of the distillation process of the crude oil in refineries. It is an oily, viscous and flammable material. Bitumen properties highly depend on crude oil type and production technology. Production technology is adjusted to the WebAsphalt is a dark brown to black, highly viscous, hydrocarbon produced from petroleum distillation residue. This distillation can occur naturally, resulting in asphalt lakes, or occur in a petroleum refinery using crude oil.In 2024, the U.S. produced about 21 million tons of asphalt ().Roads and highways constitute the largest single use of asphalt at about 80 …

The bitumens have a rather complex chemical composition. For example, they may consist of saturated hydrocarbons from С9Н20 to С30Н62. All the various organic hydrocarbon compounds that form the bitumen can be classified into three groups: solid component, tar and oil fraction. The hard part of the … See more Bitumen is a solid or retinoid product, which is a mixture of hydrocarbons and their nitrogen, kislorodnykh, sulfur and metal-containing … See more The most valuable properties of bitumen and bituminous materials is their chemical resistance to aggressive substances, which corrode … See more Bitumen (lat. bitūmen — mountain tar, asphalt) is a solid or retinoid product, which is a mixture of hydrocarbonsand their nitrogen, … See more Note: * Bitumen is an amorphous substance having no melting point.

Chemical Composition of Bitumen: Molecular weight wise, bitumen is a mixture of about 300 – 2000 chemical components, with an … WebAsphalt is a mixture of moderate molecular weight hydrocarbons, dominantly aliphatic and aromatic, and containing moderate amounts of sulfur, small amounts of oxygen and nitrogen, and other trace elements including transition metals. The physical and chemical characteristics of asphalt are consequences of its chemical composition. WebThe composition of bitumen is usually given in terms of the relative quantity of its so called SARA fractions. For saturate, aromatics, resins, and asphaltenes, as shown on this figure. It has to be noted that the percent of each SARA fractions depends on the crude origin, manufacturing process, and grade of analyzed bitumen. el rey jesus church
