(2) activation of the carbonaceous material from elutrilithe and pitch to prepare activated carbon and (3) hydrothermal conversion (zeolitisation) of aluminosilicate in elutrilithe and additional SiO2 to zeolite X in alkaline medium. The adding of additional SiO2 in the reaction system to adjust SiO2/Al2O3 ratio of the reaction mixture was necessary for the formation of zeolite X. The char- acterization of XRD, SEM and N2 adsorption of the resulting composites had a hierarchical pore structure, which shows that pure X-type zeolite phase with high crystallinity could be obtained regardless of the content of carbon in the composites.
