Coal gasification fine slag (FS) is a typical solid waste generated in coal gasification. Its
current disposal methods of stockpiling and landfilling have caused serious soil and …

Vast quantities of ash are produced in coal combustion power stations annually. Including
aluminosilicate matrix, all ashes also contain unburned carbon (UC) of varying amounts; in …

The chemical–structural properties of four South African bituminous coals were investigated
using wide angle X-ray diffraction–carbon fraction analysis (WAXRD–CFA), attenuated total …

Several animal (lamb, poultry and swine) fatty wastes were pyrolyzed under nitrogen, in a
laboratory scale fixed-bed reactor and the main products (liquid bio-oil, solid bio-char and …

The generation of coal chars is an important intermediate step in coal conversion processes
such as combustion and gasification. The char structure impacts their behaviour in these …

This study provides a review on research for improving the properties and qualities of coking
coal and metallurgical coke using preheating. Factors such as coal type, preheating …

Bio-char samples were prepared from gasification of corn straw under N 2, CO 2 and H 2 O
conditions, and systematically characterized to reveal the effects of gaseous agents on the …

Gasification fine slag contains a high content of carbon, which causes waste of resources
and environmental hazards. In essence, fine slag is a comprehensive reflection of the …

The purpose of the study was to present application of micro-Raman spectroscopy for
examination of coal macerals and to characterize the internal structure of semifusinite and …

The formation and evolution of micropore was controlled by molecular structure to a certain
extent. To study the influence of chemical structure on micropore structure, a well …
