Fusel oil, a by-product of bioethanol production, can be considered as a low-value and renewable material for transforming into value-added products. In this work, the catalytic cracking of fusel oil was studied in a fixed bed reactor to produce light olefins. The operating parameters, such as the temperature, feed flow rate of fusel oil, feedstock, and the co-feeding water, were investigated over a HZSM-5 catalyst in terms of the yields and distribution of the gaseous products. The highest total carbon in the gaseous products with excellent ethylene and propylene selectivity (44.7%, 34.4%, and 28.6%, respectively) were obtained at 550 °C, a feed flow rate of 0.04 mL/min, and 0.02 g of catalyst. After a long time on stream (TOS), the stability of HZSM-5 was slightly decreased due mainly to coke deposition. Thus, the catalytic cracking of fusel oil shows the ability to be converted into light olefins. However, catalyst improvement to enhance the catalytic activity and stability is still required, at the same time, the technical process with economic feasibility still needs more development in order to be realistically useable on an industrial scale in the future.

杂醇油是生物乙醇生产的副产品，可被视为一种低价值的可再生材料，可转化为增值产品。在这项工作中，杂醇油在固定床反应器中催化裂化生产轻烯烃进行了研究。在 HZSM-5 催化剂上研究了操作参数，如温度、杂醇油的进料流速、原料和共同进料的水，在气态产物的产率和分布方面进行了研究。在 550 °C、0.04 mL/min 的进料流速和 0.02 g 催化剂下获得了具有优异乙烯和丙烯选择性（分别为 44.7%、34.4% 和 28.6%）的气态产物中最高的总碳。在长时间运行（TOS）后，HZSM-5 的稳定性略有下降，主要是由于焦炭沉积。因此，杂醇油的催化裂化显示出转化为轻烯烃的能力。然而，仍需对催化剂进行改进以提高催化活性和稳定性，同时经济上可行的技术工艺仍需进一步开发，以便未来可在工业规模上实际应用。
