Mazut is a heavy, low quality fuel oil which is the residue from distillation of gasoline, ligroin, kerosene, and diesel oil fractions from petroleum. It may also be used as boiler fuel oil, in the preparation of distillate and residual lubricating oils, in cracking or hydrogenation processes for the manufacture of motor fuel (gasoline or diesel oil), and in the production of bitumen and coke, depending on its chemical composition and properties. It comprises all residual fuel oils, including those obtained by blending. Its kinematic viscosity is above 10 cSt at 80°C. The flash point is always above 50°C and the density is always higher than 0.90 kg/l.
The types include;
The main difference between the different types of Mazut-100 is the content of sulfur. The grades are represented by these sulfuric levels:
• "Very Low Sulphur" is mazut with a sulfur content of 0.5% • "Low Sulphur" is a mazut with a sulfur content of 0.5-1.0% • "Normal Sulphur" is a mazut with a sulfur content of 1.0-2.0% • "High Sulphur" is a mazut with a sulfur content of 2.0-3.5%

Types of Mazut

• CST 180
• CST 230
• CST 280
• CST 380
• M 100

Top uses of Mazut

• Generating plants and similar applications. In the United States and Western Europe, Mazut is blended or broken down with the end product being diesel.
• For heating houses in former USSR and in countries of Far East that do not have the facilities to blend or break it down into more traditional petro-chemicals. In the west, furnaces that burn mazut are commonly called “waste oil” heaters or “waste oil” furnaces.

Specifications & Characteristics

The less Sulphur, the better, 0.05% is the super quality for vehicles, etc., while other qualities are for generators, power plants, etc.
