摘要

轻烷烃芳构化制备芳香族化合物在石油化工中的应用是一个有吸引力的研究领域。研究了二次金属共浸渍对丙烷芳构化ZSM-5中锌的稳定作用。采用co湿浸渍法对HZSM-5进行了锌和铁金属改性,并利用XRF、XRD、BET、n2吸附、FTIR、FTIR-吡啶、SEM、TEM、H2-TPR和XPS对其进行了表征。研究了不同载铁量对Zn/ZSM-5的酸度、芳香收率、产物分布和芳香化性能的影响。性能试验在540℃的固定床反应器中进行。°C,一个大气压。GHSV为1200ml /g-h。Zn与Fe共浸渍提高了10?与母体HZSM-5和Zn/ZSM-5相比,其芳香收率和丙烷转化率非常低。在HZSM-5上浸渍Zn作为脱氢金属,芳香收率从HZSM-5上的5%稳步提高到25%,10?h TOS。铁的共浸渍1-3 ?Wt %负载作为锌稳定性的第二种金属。在ZSM-5上添加wt% Zn后,10?h TOS。这进一步增强了芳香产品的分布,并减少了轻气体。

Highly selective and stable Zn–Fe/ZSM-5 catalyst for aromatization of propane

Light alkane aromatization for aromatic compound production, used in petrochemical industries is an attractive area of research. The effect of second metal co-impregnation was investigated in stabilizing zinc on ZSM-5 in aromatization of propane. HZSM-5 was modified with zinc and iron metal by co wet-impregnation and characterized using XRF, XRD, BET, N2-adsorption, FTIR, FTIR-Pyridine, SEM, TEM, H2-TPR and XPS. The effect of different loadings of Iron on Zn/ZSM-5 was investigated on acidity, aromatic yield, product distribution and aromatization performance. Performance test was conducted in a fixed bed reactor at 540?°C, one atmosphere. GHSV of 1200?mL/g-h. Co-impregnation of Zn with Fe improved the catalytic activity and aromatic yield for 10?h time on stream as compared to parent HZSM-5 and Zn/ZSM-5 of very low aromatic yield and propane conversion. Impregnation of Zn as the dehydrogenating metal on HZSM-5 steadily increased aromatic yield from 5% on HZSM-5 to 25% and was steadily dropped to 20% after 10?h TOS. The co-impregnation of iron of 1–3?wt% loading as the second metal for zinc stability with 2?wt% Zn on ZSM-5 improved propane conversion and aromatic yield to 55% for the 10?h TOS. This further enhanced aromatic product distribution and minimized light gases.
