computer controlled weighing of the carbon samples in benzene vapours at normal pressure and room temperature in time the volume of pores that adsorbed benzene under the above described conditions was calculated according to the equation w s m 2 u2212 m 1 m 1 u00d7 d c 6 h 6 4 where m 1 and m 2 are the initial and final weights of the test sample respectively and d c6h6 is the density of benzene at room temperature specific surface s bet according to bet pore volume according to benzene w s and nitrogen v tot and incremental pore volume v d lt 11 u00e5 according to bjh method of carbon of the invention compared to the prior art are presented in table 2 the pore size distribution presented in fig1 and fig2 according to the density functional theory confirms the modified microporous structure of carbon of this invention compared to that of the prior art the effect of oxidation during chlorination is also obvious in hrtem picture in fig3 the bulk carbon of this invention is notably coarser compared to the material of prior art fig4 according to the second embodiment of the invention the fluidized bed reactor was loaded with titanium carbide pacific particulate materials 400 g with an average particle size of u02dc 70 u03bcm and flowed with the argon until the reaction temperature.
