The global economy is threatened by the depletion of fossil resources and fluctuations in fossil fuel prices, and thus it is necessary to exploit sustainable energy sources. Carbon-neutral fuels including bio-oil obtained from biomass pyrolysis can act as alternatives to fossil fuels. Co-pyrolysis of lignocellulosic biomass and plastic is efficient to upgrade the quality of bio-oil because plastic facilitates deoxygenation. However, catalysts are required to produce bio-oil that is suitable for potential use as transportation fuel. This review presents an overview of recent advances in catalytic co-pyrolysis of biomass and plastic from the perspective of chemistry, catalyst, and feedstock pretreatment. Additionally, this review introduces not only recent research results of acid catalysts for catalytic co-pyrolysis, but also recent approaches that utilize base catalysts. Future research directions are suggested for commercially feasible co-pyrolysis process.
全球经济受到化石资源枯竭和化石燃料价格波动的威胁，因此有必要开发可持续能源。包括生物油在内的碳中和燃料可以作为化石燃料的替代品，生物油是通过生物质热解获得的。木质纤维素生物质和塑料的共热解可以有效地提高生物油的质量，因为塑料有助于脱氧。然而，需要催化剂来生产适合作为运输燃料的生物油。本综述从化学、催化剂和原料预处理的角度介绍了生物质和塑料共热解的最新进展。此外，本综述不仅介绍了用于催化共热解的酸催化剂的最新研究成果，还介绍了利用碱催化剂的最新方法。为了实现商业可行的共热解过程，提出了未来的研究方向。
