Typical municipal solid waste (MSW) is composed mainly of biomass and polymers. In this study, the co‐conversion of a feedstock obtained from a mixture of both constituent materials is investigated. The goal of this study was to determine the suitability of a low‐temperature process for achieving biochar with properties that can make it amenable to multiple energy and environmental applications. Co‐carbonization of oil palm (Elaeis guineensis) fiber (OPF) and low‐density polyethylene (LDPE) was conducted at a peak temperature of 529 °C for 80 min in a top‐lit updraft biomass conversion reactor using retort heating. The biochar yields for OPF and OPF‐LDPE were 15.9 wt% and 62.7 wt%, respectively, with the higher yield of the latter attributed to a polymer effect. The OPF and OPF‐LDPE biochars were mesoporous with relatively large specific surface areas of 352.9 and 391.4 m² g⁻¹, respectively. The addition of LDPE to the OPF feedstock was observed to be advantageous as it improved the biochar yield, carbon content, specific surface area, and pore volume. Consequently, the technology of choice for solid waste management offers key environment‐friendly benefits such as no electrical power requirement, an excellent waste‐to‐wealth approach, and the capacity to be used globally (in remote locations). © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd

油棕纤维-LDPE混合废料的热化学转化为生物炭

典型的城市固体废物（MSW）主要由生物质和聚合物组成。在这项研究中，研究了由两种组成材料的混合物获得的原料的共转化。这项研究的目的是确定一种低温工艺是否适合于获得生物炭，其特性应使其适合多种能源和环境应用。油棕共生碳化）纤维（OPF）和低密度聚乙烯（LDPE）在顶部加热的立式生物质转化反应器中通过re式加热在529°C的峰值温度下进行了80分钟。OPF和OPF-LDPE的生物炭收率分别为15.9 wt％和62.7 wt％，后者的较高收率归因于聚合物效应。OPF和OPF‐LDPE生物炭为中孔，比表面积较大，分别为352.9和391.4 m ² g ^-1， 分别。观察到将LDPE添加到OPF原料中是有利的，因为它提高了生物炭的产率，碳含量，比表面积和孔体积。因此，固体废物管理的首选技术提供了关键的环境友好优势，例如无需电力，出色的废物转化为财富的方法以及在全球（偏远地区）使用的能力。©2020年化学工业协会和John Wiley＆Sons，Ltd
