环境友好新材料的开发:微波法研制固体强碱及其在油品脱硫醇中的应用

Investigation on the Novel Environment Benign Materials: The Solid Strong Bases pepared by Use of Microwave Irradiation and their Application for Sweetening

用微波辐射能将ＭｇＯ等氧化物负载在ＮａＹ等分子筛及ＳｉＯ_２的表面上，形成具有强碱性和高比表面的复合新材料，并实现了制备过程中的“零排放”而成为环境友好新工艺。本文探讨了沸石孔结构、表面含水量以及客体性质对于微波法制备样品的影响，并探讨了新型固体强碱在汽油脱硫酸工艺中的应用。

Oxides such as MgO could be well dispersed on the host zeolite NaY or SiO_2, forming a coated layer on the surface of host by use of the microwave irradiation. Compared with the common methods such as ion exchange or impregnation, microwave irradiation costs less time, energy and money, and the operation is simpler. The resulting novel porous material has a strong basicity and a large surface area similar to host; Moreover, no any pollution was caused during the preparation process that is thus proven to be an environment benign one. In this paper the influence of many factors on the microwave irradiation, including the pore structure and the surface state of zeolite was investigated, and the intrinsic properties of guest materials were also discussed. The application of the new solid strong bases for sweetening was also investigated.
