With the raw material of gas coal and weakly caking coal-char,a set of formed cokes were prepared by changing the size of gas coal and weakly caking coal-char.

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).
