The rapid thermal cracking technology of biomass can convert biomass into bio-oil and is beneficial for industrial applications. Agricultural and forestry wastes are important parts of China's energy, and their high-grade utilization is useful to solve the problem of energy shortages and environmental pollution. To the best of our knowledge, the impact of nanocatalysts on converting biowastes for bio-oil has not been studied. Consequently, we examined the production of bio-oil by pyrolysis of Aesculus chinensis Bunge Seed (ACBS) using nanocatalysts (FeO and NiO catalysts) for the first time. The pyrolysis products of ACBS include 1-hydroxy-2-propanone (3.97%), acetic acid (5.42%), and furfural (0.66%). These chemical components can be recovered for use as chemical feedstock in the form of bio-oil, thus indicating the potential of ACBS as a feedstock to be converted by pyrolysis to produce value-added bio-oil. The FeO and NiO catalysts enhanced the pyrolysis process, which accelerated the precipitation of gaseous products. The pyrolysis rates of the samples gradually increased at DTG effectively promoting the catalytic cracking of ACBS, which is beneficial to the development and utilization of ACBS to produce high valorization products. Combining ACBS and nanocatalysts can change the development direction of high valorization agricultural and forestry wastes in the future.
生物质的快速热解技术可以将生物质转化为生物油，有利于工业应用。农林废弃物是中国能源的重要组成部分，其高品位利用有利于解决能源短缺和环境污染问题。据我们所知，纳米催化剂对生物废物转化为生物油的影响尚未得到研究。因此，我们首次使用纳米催化剂（FeO 和 NiO 催化剂）研究了麻疯树种子（ACBS）的热解生产生物油。ACBS 的热解产物包括 1-羟基-2-丙酮（3.97%）、乙酸（5.42%）和糠醛（0.66%）。这些化学组分可以作为生物油的形式回收用作化学原料，从而表明 ACBS 作为原料通过热解生产增值生物油的潜力。FeO 和 NiO 催化剂增强了热解过程，加速了气态产物的沉淀。样品的热解速率在 DTG 处逐渐增加，有效促进了 ACBS 的催化裂解，有利于 ACBS 的开发利用，以生产高附加值产品。ACBS 和纳米催化剂的结合可以改变未来农林废弃物高附加值的发展方向。
