Ni/ZnO Nano Sorbent for Reactive Adsorption Desulfurization of Refinery Oil Streams

Sulfur Adsorption

The aim of this chapter is to present the Ni/ZnO nano-sorbent for reactive adsorption desulfurization (RADS) of refinery oil steams. The preparation and modification of nano-sorbent are reviewed. Various characterizations involving in the relation of properties with components, structures and dynamic phase change during RADS, are extensively provided. The mechanisms of desulfurization, sulfur transfer and sulfur adsorption are proposed. The contradictories in literature about active structures and reaction mechanism are discussed and the solutions are suggested. This chapter unfolds the impressive application of RADS of Ni/ZnO nano-sorbent to produce a cleaner gasoline. It also delves into the inadequately engineer areas which require further attention so as to make the RADS process more economic and more efficient. The perspective applications other than gasoline desulfurization are also presented.

Sulfur Adsorption

Ni/ZnO nano-sorbent systems have been extensively used in the reactive adsorption desulfurization (RADS) of gasoline steams, especially in China, to meet the more rigorous regulation on the sulfur content. The apparent advantage of RADS is that most of the olefins are kept in the product with low consumption of hydrogen and little loss of octane. The authors discussed in this chapter the relation of catalytic properties with components and structures of Ni/ZnO sorbent. Based on detailed characterization and reaction results, they revealed the dynamic change of Ni/ZnO sorbents during RADS, the mechanisms of desulfurization, and the sulfur transfer and sulfur adsorption. Apart from the RADS of Ni/ZnO nano-sorbent for cleaner gasoline production, they also presented other potential applications.

Co Precipitation

The oxides adsorbent of NiO-ZnO/-Al2O3-SiO2 was prepared by co-precipitation method. SEM, XRD and BET studies were performed to understand the structural properties of the adsorbent. And the adsorbent can be used for the desulfurization of thiophene in n-hexane as model gasoline. Removal rate of thiophene increased with increasing reaction time. Removal rate of thiophene in equilibrium decreases with increasing the initial concentration of thiophene. The extent of adsorption in adsorbent increased with increasing the initial concentration of thiophene. The removal rate of thiophene increases with increasing reaction temperature, it showed that the desulfurization is a chemical process not a physical process.
