MXCOL® (pronounced “M-X-COAL”) is the name and trademark for the use of syngas derived from coal in the commercially proven MIDREX® Direct Reduction Process.

MXCOL® can use reducing gas from several sources of syngas:

  • Commercial gasifiers using a variety of low cost fuels
  • Export gas from the coal-based COREX® Hot Metal Process by Siemens VAI Metals Technologies GmbH
  • The MIDREX® Thermal Reactor System™ (TRS®).

The first commercial application of MIDREX® Technology using syngas from coal was commissioned in 1999 at ArcelorMittal Steel South Africa (formerly Saldanha Steel). Here the export gas from a COREX® Plant is used in a MIDREX® Shaft Furnace to supply DRI to the meltshop in addition to the hot metal from the COREX® Plant.
