Abstract In mostDirect Reductionprocesses reducing gasis producedbycatalytic reforming ofnatural gas with steam CO2 or mixture ofboth Presently the catalystsusedin Ahwazand Mobarakeh steelcomplexes imported are from other countries In this research attempts weremadeto produce catalysts that can be used in DirectReductionplants Samplesof the importedcatalystswerefirst examinedusing XRD phaseanalysis and SEM electronmicroscopy Using theseresults several techniqueswereusedto prepare catalyst support and impregnate it with Nickel The effects of differentsparameters on support preparation and impregnation werestudies Thesewereparticlesizedistribution additives time temperature solution concentration pH etc A fewtestswerealso carried out using the preparedcatalyststo studythe reforming of naturalgas with CO2 The results werecomparablewith importedcatalysts t I Ii J I liJ pJr J Y ii I I I 1
