Title:
CARBONACEOUS MATERIAL FOR SINTERING IRON ORE
Document Type and Number:
WIPO Patent Application WO/2010/087468
Kind Code:
A1
Abstract:
Provided is a fuel for sintering iron ore which is less expensive and more efficient in sintering than sintering fuels that have been used conventionally, can improve the productivity of sintered ore and the product yield thereof, and can reduce the emission of nitrogen oxides in the course of the production of the sintered ore. A carbonaceous material to be used as a fuel in sintering iron ore which has the following properties: (i) the reaction starting temperature being lower than or equal to 550°C; (ii) the content of volatile matters (VM) being greater than or equal to 1.0%; (iii) the atomic ratio of hydrogen to carbon (H/C) being greater than or equal to 0.040; and (iv) the 0.1-10 μm pore volume measured by the mercury porosimetry being greater than or equal to 50 mm3/g.
