Heavy fuel oil TKK is a liquid alternative fuel that obtained by coke processing and consists of three base chemical components:
1. Anthracene fraction 40%
2. Naphthalene fraction 30%
3. Absorption fraction 30%
TKK manufactured in Ukraine according to technical conditions TU U U 24.1-00190443-121-2001
TKK is an analog of heavy fuel oil named Mazut M-100, but TKK has two main advantages over Mazut M-100 such as:
1. The price of TKK is lower than the price of Mazut M-100 more than 10% per metric ton.
2. Congelation point of TKK is not more than 8 °С, at that time Mazut M-100 congelation point is +25 °С. That is why usage of TKK in cold conditions is most rational than usage of Mazut M100 that requires heating.

TKK can be used for heat and steam generation in such industry as:

1. Heating systems, boilers (heat generation for housing and utilities infrastructure).
2. Alcohol plants, canneries and dairy plants, brick and glassware plants, asphalt plants, tire plants (steam generation).
3. Plants producing carbon black (raw material for carbon black).
4. Elevators, silos, grain-points (heat generation for drying cereals).
5. Foundry (heat generation to melt the metal).
And many others.

Export code of TKK is 2707 99 99 00.
