不同模板剂对纳米氧化铁形貌及硫化性能的影响
Impacts of different templates on the morphologies and sulfuration performances of nano ferric oxides
摘要
Abstract
Nano ferric oxides with different morphologies were successfully prepared via a facile hydrothermal method. Analytical grade Fe(NO3)3·9H2O,CO(NH2)2and different template agent including glycerol,cetyltrimethyl ammonium bromide(CTAB)and tartaric acid were employed as raw materials. X-ray diffraction(XRD),scanning electron microscope(SEM)and nitrogen adsorption-desorption isotherms(BET) were used to characterize the phase composition,morphologies and pore structure of as-prepared products. The results revealed that the obtained pure Fe2O3crystals were spherical,rod-like or cuboid structures. Moreover,the template agent played an important role in controlling the shape and size of the products. The desulfurization behaviors were also investigated in a micro reactor. The three sorbents with different morphologies all showed excellent H2S capture ability. Specifically,the sorbent used tartaric acid as template agent showed enhanced desulfurization performance than others,of which,the breakthrough time reached 350min,and the corresponding sulfur capacity was 11.5g/100g sorbent. In this paper,we prepared desulfurizer active group with different morphologies by adding template agent,which could increase the sulfuration properties,and provide new thoughts for high efficiency desulfurization.关键词
