Preparation and Reactive Adsorption Desulfurization  Performance of ZnO Hollow Microspheres
Guan Zongchi, Kang Lei, Wang Haiyan, Zhong Dongkui
Abstract476)      PDF (2605KB)(226)      
Zn(OH) 2 carbon composite microspheres were prepared by hydrothermal method using sucrose as template and then roasted to form the ZnO hollow microspheres. The effects of calcination rate on the morphology and pore structure of ZnO hollow microspheres were investigated. The structures of the hollow microspheres were characterized by XRD, TG, SEM and N 2 adsorption. Then, the NiO/ZnO adsorbents with 5% Ni content were prepared by equal volume impregnation method. The results show that when the calcination rate is 3 ℃/min, the specific surface area and pore volume of hollow microspheres are as high as 37.21 m 2/g and 0.483 cm 3/g respectively; when the adsorption temperature is 350 ℃, the pressure is 1.2 MPa, the volume space velocity is 6 h -1 and the volume ratio of hydrogen to the simulated oil is 60, the desulfurization rate of the Ni/ ZnO adsorbent can reach as high as 96%, which has potential value in application.

Abstract320)      PDF (166KB)(194)      
    Paraffin wax was mix ed with microcry stalline paraffin wax by the mass ratio o f 4∶1.The total mass is 100 g .The catalyst and cocatalyst were added.The oxidation reaction w as taken place at the certain reaction temperature, air flow , and reaction time.The analysis of the heat -effect indicates that the maximum energy of forming the free radical and the activation energy are greatly affected by the air flow and the reaction temperature .When the air flow is 4 L/min, the temperature is 170 ℃, the maximum energy of forming the free radical and the activation energy are lower , the reaction is easy to occur .The forming of free radical is greatly affected by the mass of the catalyst and  cocatalyst .When the catalyst mass is 0 .016 g and the cocatalyst mass is 1 .6 g , the free radical is easy to be formed.The optimal reaction time is 6 h .
