1. The distribution of elements at the sulfidation reaction product section of a sodium salt-modified desulfurization agent was analyzed by using the energy-spectrum scanning function of SEM.

2. Results reveal that the impregnation, drying, calcination and sulfidation are all important processes for the mechanical strength and reliability.

3. Effects of temperature programmed sulfidation process on sulfidation of the catalyst was investigated after sulfidation.

4. Increasing sulfidation temperature and time can enhance the resistivity of the pyrite films.

5. Results reveal that the impregnating, drying,(Sentencedict.com) calcination and sulfidation are all important processes for the mechanical strength and reliability of the catalyst.

6. The sulfidation performance of iron oxide prepared from various precursors was investigated, and the ferric nitrate with better sulfidation performance was chosen as precursor of active component.

7. The sulfidation of fresh phosphides and sequential HDS-HDN experiments revealed that sulfur played a positive role in the HDS reactions over metal phosphides.

8. Many factors have been confirmed to influence the sulfidation behavior of the iron aluminides intermetallics such as alloying component, corrosion atmosphere, temperature and pretreatment conditions.

9. The result showed that the agent was effective for sulfur removal and could be well regenerated, and sulfidation at higher temperature brought about higher sulfur capacity.

10. In rubber industry, they can be used as dispersant to facilitate sulfidation and be used as dispersant of carbon filler.

11. The key of the CO shift process is applying sulfidation resistance shift catalyst, so that the feed gas with sulfide can be shifted directly without removing sulfide.

12. Moreover, the electrical resistivity decreases while the carrier concentration increases with increasing the sulfidation temperature.

13. Based on the practice, this paper discusses the package sulfidation and maintenance of sulfur resistance lower temperature conversion catalyst in utilization.

14. The reasons for this phenomenon and the influence of the sulfide scale demixing on the sulfidation process of Fe-Cr alloys have been discussed.

15. Based on analyses of the structure and composition of sulfide scales, the sulfidation mechanisms of the alloys with different additions have been proposed.

16. The XPS results show that binding energy of metal oxide of fresh and regenerated sorbents hardly changed. So the sulfidation and regeneration processing is feasible for AC28 sorbent.

17. The presence of water vapor always inhibited reduction and sulfidation process.

18. They can be transformed into sulfide and become active for HDS reaction at normal sulfidation conditions.
