Investigation on Effect of Raw Coal's Granularity on Pore Structure and Adsorption Properties of Carbonized Material
-
Abstract
The low ash anthracite from Ningxia was heated by box-type resistance furnace to prepare carbonized material.Microstructure and phase of carbonized material were characterized by scanning electron microscope (SEM) and X-ray diffractometer(XRD).The effects of raw coal's granularity on adsorption properties and pore distribution of carbonized material were studied by testing its methylene blue adsorption value and N2 adsorption.The results show that the carbonized materials,which were prepared with 0.2 ~0.3 mm raw coal at 5 ℃/min heating to 550 ℃ for 2 h,have many graphite crystallites which form pore structure as carbon-skeleton.The pores and holes distributed equably in carbonized material.As the granularity of raw coal decreased,the surface area and micropore of carbonized material increased,but total pore volume decreased. -
