Carbonization products C1,C2,C3,C4 and C5 were prepared by the carbonization of date pit in limited air,at 500,600,700,800 and 1000℃, respectiveiy. C1-V-600,C3-V-600,C1-V-1000 and C3-V-100 were prepared by thermal treament of C1 and C3 under vacuum at 600 and 1000℃. The textural properties were derermined from nitrogen adsorption at 77K and from carbon dixide adsorption at 298 K.
