Study on the carburizing character of iron catalysts by temperature programmed surface reaction of carburization
The promotion effect of potassium has been studied with the method of Temperature Programmed Surface Carburization (TPSC) technique and H-2-TPR. The process of carburization on the catalyst surface was enhanced by addition of potassium was added, so that the probability for the generated alkenes species to be further hydrogenated was increased. As a result, the percentage of the alkenes from C2 to C4 in the products was increased.
