| Inhoud: |
Sulfur uptake by reduced Mo03 and CoMoO4 catalysts when passing H235S pulses was measured. Also, the release of labelled sulfur was monitored when thiophene and cyclohexanol pulses were reacted over these catalysts. The sulfur release was about 20% of the retained amount in the H2S/thiophene system. Here the conversion of thiophene in HDS was inversely proportional with the amount of irreversibly retained sulfur. A few pulses of cyclohexanol could stop sulfur uptake indicating that oxygen can be more firmly held by the catalyst than sulfur. All these arc in favor of interpreting the active sites as anion vacancies. @KEYWORDS: Catalysts, Sulfur, Radiotracer, Mo and Co-Mo Catalysts. |
