Ordered carbon material that preserves the structural regularity of the parent zeolite template was synthesized by using ethylene as carbon source and HY-zeolite in a batch reactor. The obtained carbons exhibit a high degree of microporosity having BET surface areas between 1400 and 2400 m(2)/g. The morphology and structure of the prepared carbon materials were investigated by elemental analysis, X-ray diffraction measurements, scanning electron microscopy and nitrogen adsorption. The results were compared with the parent zeolite template. The carbonization procedure of precursor-encapsulated samples was investigated by thermal analysis and it has been found that the resulting quality of the ordered carbons strongly depends on the heat treatment of the composite material.
