It states the status of energy consumption of the blast furnace production,and analyzes the main reasons for influencing pulverized coal injection coke suppression on blast furnace prodution.

Review of study on gasification characteristic of coal char with carbon dioxide and steam;

Characteristic of the Shenfu coal char gasification with steam and carbon dioxide;

Study on reduction of NO by coal chars;

Its main energy source is non-coking coal and its product is simliar to pig iron produced in blast furnace.

The sorption characteristics of the single-component gas(CH4,N2,CO2) and the binary gas with different proportion(80% CH4+20% CO2,50% CH4+50% CO2,20% CH4+80% CO2,80% CH4+20% N2,50% CH4+50% N2,20% CH4+80% N2) on long-flame coal,coking coal and anthracite were studied by means of isotherm adsorption experiment in laboratory.

Four carbonaceous additives include coking coal,1/3 coking coal,hard coal-based pitch and charcoal were selected to study their influence on the properties of the agglomerated activated carbon(AC) made from Datong bitumite.

Catalytic mechanism of alkali metal on NO heterogeneous reduction by char:quantum chemistry study;

Investigation on Char Characteristics and Their Effect on Ash Formation;

The functionalities of nitrogen in Yibin coal and in whose chars are determined by Xray photoelectron spectroscopy (XPS).

Effect of heat treatment on the reactivity and microstructure of coal-char;

The effect of heat treatment on the catalytic capability of minerals for the oxidation of coal-char prepared from the vitrinite of YX coal and JJ coal was investigated using XRD and TGA.

Thermogravimetric experiments of Yanzhou bituminous coal-char and Jianyang anthracite-char under O2/CO2 atmosphere and O2/N2 atmosphere are studied.
