In this study the results of calculation of rate constants for graphite gasification reaction (reverse Boudouard reaction) taking into account heat andmass transfer processes at temperatures of 900-1200°C are presented.The calculation of rate constants ofC+CO2 reactionongraphite inpresenceofcalcium,magnesium, strontium, iron (II) and iron (III) oxides, strontiumcarbonate andmetallic ironwas performed.The graphs of linear dependencies of pre-exponential factor on acti- Original Article ChemXpress 5(3), 078-088, (2014) ISSN(Print) : 2320 –1967 ISSN(Online) : 2320 –1975 vationenergyforcalcium, strontiumandironcompounds were plotted. The isokinetic temperatures for various groups of catalystswere calculated.
