Mazut M100

Mazut M100


Mazut is the residue from distillation of gasoline, ligroine, kerosene, and diesel oil fractions from petroleum.

Mazut is a heavy, low quality fuel oil, used in generating plants and similar applications. In the United States and Western Europe, mazut is blended or broken down, with the end product being diesel.

The main difference between the different types of Mazut-100 is the content of sulphur. The grades are represented by these sulfuric levels:

  • ”Very Low Sulphur” is mazut with a sulphur content of 0.5%
  • ”Low Sulphur” is a mazut with a sulphur content of 0.5-1.0%
  • ”Normal Sulphur” is a mazut with a sulphur content of 1.0-2.0%
  • ”High Sulphur” is a mazut with a sulphur content of 2.0-3.5%

Main Applications:

  Boiler fuel oil

  The preparation of distillate and residual lubricating oils

Cracking processes for the manufacture of motor fuel (gasoline or diesel oil)
