GILSONITE – OXIDIZED BITUMEN

GILSONITE – OXIDIZED BITUMEN FOR INDUSTRY



Gilsonite is mined ore as natural resinous hydrocarbon, and it is also called natural asphalt. This natural asphalt is similar to hard petroleum asphalt and is often called a natural asphalt, asphaltite, uintaite in US, or Asphaltum. This ore is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt and it reacts with petroleum compounds as a polymer chemical substance. Due to its unique compatibility, Gilsonite is frequently used to harden softer petroleum products. Gilsonite in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder


Gilsonite, is very important in fuel processing industry, matching and interpreting the results from different techniques. The Gilsonite was characterized by elemental analysis (EA) to determine the concentrations of C, H, N, S, and O, by Fourier transform infrared spectroscopy for comparative analysis of the chemical structures, by Nuclear magnetic resonance spectroscopy of hydrogen (1 H NMR) to ascertain the aliphatic and aromatic hydrogen fractions, and by Thin layer chromatography-flame ionization detection (Iatroscan TLC FID) to quantify saturated and aromatic hydrocarbons, and resin/asphaltene fractions


It has low hydrogen to carbon atomic ratio 1.44, it has low sulfur value 0.27 % and high nitrogen 3.25 % contents were the main characteristics. FTIR revealed the presence of alkane, aromatic rings, phenyl rings, alcohols, carbonyl groups, organic sulfoxides, and sulfate salts, confirming the fact that Gilsonite is composed of high molecular weight polycyclic constituents comprising of nitrogen, sulfur and oxygen heteroatoms

This unique mineral is used in more than 160 products, primarily in dark-colored printing inks and paints, oil well drilling muds and cements, asphalt modifiers, foundry sands additives and a wide variety of chemical products. Gilsonite was a shiny, black substance similar in appearance to the mineral obsidian

Application of gilsonite:

  1. cement companies
  2. pipeline companies
  3. metal foundries
  4. refineries
  5. construction companies (constructing roads and cities)
