In recent years, nanoscale metal-contaning materials as catalysts for the syngas processing have increasingly garnered the interest of the researchers. The syngas processing (hydrocarbon synthesis from carbon monoxide and hydrogen) is a second stage of the most recycling processes of non-oil raw materials (coal, natural or associated gas, peat, etc.) to eco-friendly fuel components. Syngas processing is catalyzed by metals in bulk state or distributed on the surface of a highly porous support. Their catalytic activity, selectivity and stability is defined by the shape and size of the applied active component particles. Application of ultrafine catalyst systems allows the conversion reaction of synthesis gas with high efficiency in the traditional fixed bed reactors and in three-phase slurry reactors.
At synthesis of nanoheterogeneous contacts in liquid hydrocarbon medium nanosize stable suspensions with a size of particles no more than 50 nm are obtained. The disperse phase in such disperse systems isn't inclined to sedimentation that does them perspective for industrial realization in liquid-phase slurry -reactors.
At synthesis of nanoheterogeneous contacts distributed in solid organic matrix methods for polymercontaining composite materials obtaining are used. Initial organic matrixes represent polyconjugated systems decomposing to carbon during formation of the catalyst. Thus particles of 10-20 nm in size metal are formed from salts immobilized on polymers.
Various physical-chemical methods of investigation of nanosized catalysts of synthesis gas conversion – IR- spectroscopy, magnetometry in situ, Mössbauer spectroscopy, X-ray diffraction, molecular modeling techniques will be described.
