摘要:
合成了ZSM-5/SBA-15复合分子筛材料,并对其晶型结构、孔道参数、酸性质等物理化学性质和加氢异构化性能进行了表征和评价。结果表明:所合成的复合分子筛具有ZSM-5和SBA-15分子筛骨架结构,适宜的酸性和独特的介-微复合孔道结构;将其作为载体负载金属Pt后制得的Pt-ZSM-5/SBA-15催化剂,在正辛烷的加氢异构反应中,较纯硅SBA-15基催化剂Pt-SBA-15、微孔ZSM-5分子筛基催化剂Pt-ZSM-5和ZSM-5与SBA-15物理混合基催化剂Pt-ZS-H,具有更高的双支链异构产物选择性和较低的裂化选择性。
Abstract:
The ZSM-5/SBA-15 micro-mesoporous composite was prepared, and its physicochemical properties (such as crystalline and pore structures and acidity) and catalytic performance in alkanes hydroisomerization were systematically characterized and evaluated, respectively. The results showed that the obtained ZSM-5/SBA-15 composite had both the framework structure of ZSM-5 and SBA-15, suitable acidity and unique meso-microporous structure. The catalyst Pt-ZSM-5/SBA-15 obtained by loading Pt on ZSM-5/SBA-15 support exhibited higher selectivity to di-branched isomers and lower selectivity to cracking than the pure silicon SBA-15 based catalyst Pt-SBA-15, microporous ZSM-5 based catalyst Pt-ZSM-5, and the physical mixture of ZSM-5 and SBA-15 based catalyst Pt-ZS-H in the hydroisomerization of n-octane.
