Abstract:
The two stage technology of porous carbonaceous material obtaining via pyrolysis in inert medium with subsequent activation by steam is well-known. While steam could be a suitable substance for pyrolysis as well, the single-staged technology for waste tires recycling is yet to be developed. A comparative analysis of the characteristics of the carbonaceous materials obtained by the single-staged steam pyrolysis of waste tires was carried out, which could provide theoretical background for development of such technology. The steam pyrolysis was performed in a tubular reactor in an overheated steam medium (500 °C with 5 kg/h mass flow rate). The technical characteristics of the obtained samples were evaluated in context of their potential for further application as absorbent and raw material for the rubber production according to Chemical Abstracts Service No. 1333-86-4. The composition and physical-chemical properties of the obtained samples were studied using BET and thermogravimetric analysis, atomic emission, transmission and scanning electron microscopies, Raman, X-ray diffraction and photoelectron spectroscopies. The results revealed that the structure and properties of all obtained carbonaceous material samples were similar. The samples consisted of amorphous carbon (with a disordered graphite lattice) and contained a significant amount of metal oxides. According to experimental data, zinc was present in the form of ZnO with a binding energy of 1022.4 eV, while sulfur was observed in the form of sulfide and oxysulfide with binding energies of 161.8 and 163.2 eV, respectively. According to electron microscopy, the morphology of samples was represented by a set of spherical agglomerates comprising nanosized particles. According to the BET analysis of the samples, the specific surface area was varied in range between 52.0 and 66.0 m2/g, the pore volume values were within a range of 0.53–0.87 cm3/g while the average pore size was varied from 412 to 527 Å.
