SPECTROSCOPIC STUDIES OF THE DETERMINATION OF CHAIN GROWTH INTERMEDIATE IN THE FISCHER-TROPSCH SYNTHESIS REACTION ON THE BIMETALLIC SUPPORTED SYSTEM

The ruthenium-manganese bimetallic alloy system was prepared by co-imp regnation method from the ionic solution of ruthenium chloride and man ganese chloride dispersed on the high surface area aluminium oxide sup port and reduced to metallic form at 450 degrees C under hydrogen flow . The prepared sample was characterised using BET surface area measure ment and atomic adsorption spectroscopy.The prepared sample was then s ubjected to carbon monoxide hydrogenation reaction in the continuous f low reactor. The sample was then taken out of the reactor and transfer red to Secondary ion mass spectrometer, X-ray photo electron spectrome ter and Infra red spectrometer for study. The study indicates the pres ence of CH2 group on the surface. On the basis of this intermediate a mechanism for the formation of higher hydrocarbons in the Fischer Trop sch Synthesis has been postulated. In this manuscript modern spectrosc opic techniques have been used in determining the chain growth interme diate for the well known Fischer Tropsch Synthesis used for the produc tion of hydrocarbon products in the Petrochemical Industry.
