THE 2. GENERATION COKE

A reactive nanostructured reducing coke

Highly porous and highly active

The 2. generation coke is produced by thermal processing of coals by use a new patented technology

Resulting in a multifunctionalreducing agent with high chemical activity

The new reducing agent is made for effective interaction in heterogeneous environment with solid gas.

It has been specially created structure consisting tunnel of macro,micro and nano-pores that provide maximum gas permeabilityand a large surface area of contact of the reaction gases with thepore walls at high speeds of up flow gases ferroalloy furnace.

Main differences between the new reducing agent vs. traditional structures of other carbonaceous materials used in the production of ferroalloys are:

Anisotropic highly porous structure with communicating poresopen, which ensures immediate heating of the pore walls, thusachieving efficiency of pore space in a temperature reduction ofmetal oxides.
