PP-III-9METAL CONTAINING ZEOLITES - CATALYSTS OF STEAM CONVERSION OFMETHANEKasumova N.M., Ahmedov M.M., Ismajlova N.S., Guliev A.I.Institute of Chemical Problems of the Azerbaijan National Academy of Sciences, AzerbaijanE-mail: chem@dcacs.ab.az., ximik21@rambler.ruThe practical approach to use clinoptylolyte of Aidag deposits as the carrier forimbibitions catalysts of steam conversion of methane is developed. Optimum conditions ofreaction of steam conversion of natural gas with the purpose of syn-gas production arecertained: temperature-900 °C, a volumetric ratio CH 4 /H 2 O=1÷1-3, volumetric rate of gas mix- 425-650 h -1 .One of parameters of technical progress in the developed countries is the level ofcapacities on manufacture of hydrogen and synthesis-gas. The main industrial way ofsynthesis-gas production is catalytic conversion of hydrocarbons, cheapest of which ismethane.Interest to processing of natural gas to liquid fuel and valuable chemical products, suchas, methanol, formaldehyde, methyltretbuthyl ether, dimethyl ether, etc., has stronglyincreased in connection with the rise in price of oil.Steam conversion of methane СН 4 + Н 2 О = СО + 3Н 2 , ΔН = 206,4 kJ/mole is one ofperspective processes of processing of natural gas and the main industrial way of productionof synthesis-gas, and is considered to be well studied /3/.Clinoptylolyte of Aidag deposits of the Azerbaijan Republic has been used for the firsttime as the carrier of the catalyst of steam conversion of methane. Application of naturalclinoptylolyte for obtaining synthesis-gas will allow not only to expand assortment ofcatalysts, but also to reduce raw, power expenses for its manufacturing.Ratio SiO 2 /Al 2 O 3 in clinoptylolyte testifies that it can be referred to highly-siliceouszeolites of ZSM-5 type which, as it is known, find rather wide application in processes of oilprocessing /4/.As an active component has been chosen traditional-nickel. The purpose of the presentresearch was creations of effective metal containing zeolite catalysts of steam conversion ofmethane, studying of composition and structure of the carrier, a way of preparation andconditions of activation of contact, and also an influence of the maintenance of an activecomponent of nickel in the catalyst.485
