Abstract

Abstract: Shenfu raw coal and vertical furnace semi-coke were used to be investigated.Using Nitrogen adsorption, XPS, FTIR spectrum and SEM to analyses the raw coal and semi-cokes, which showed that the specific surface area was larger and the pore structures were more developed of semi-cokes,compared with raw coal.Functional groups of semi-cokes and raw coal are similar while the contents are different.Facial functional groups have been changed after coal pyrolysis, semi-cokes facial C—C、C—O bonds were increased, C—H、C=O and O=CO bonds were reduced.

Key words: Shenfu raw coal, semi-cokes, functional?groups, pore structure, XPS
