Formation and characterization of catalytic carbons obtained from CO disproportionation over an iron nickel catalyst—I

摘要: Abstract A series of catalytic carbons has been prepared by CO disproportionation (2CO→CO2 + C) over an iron nickel catalyst. The catalyst is under the form filings (particle sizes ranging from 10 to 160 μm) alloy (75 wt % nickel, 25 iron). dependence rate carbon deposition on temperature, between 400 and 650°C, partial pressure in reacting 2 mixtures investigated. Since specific area initially very small, its fragmentation necessary obtain appreciable reaction. Experimental evidence suggest that existence a high density dislocations condition for fragmentation.
