Increasing ambient carbon dioxide (CO₂) concentration from anthropogenic greenhouse gas emission has contributed to the growing rate of global land and ocean surface temperature. Various carbon capture and storage (CCS) technologies were established to mitigate this impending issue. CO₂ adsorption is gaining prominence since unlike traditional chemical absorption, it does not require high energy usage for solvent regeneration and consumption of corrosive chemical solvent. In CO₂ adsorption, activated carbons show high CO₂ adsorption capacity given their well-developed porous structures. Numerous researches employed oil palm wastes as low-cost precursors. This paper provides a comprehensive assessment of research works available thus far in oil palm-derived activated carbon (OPdAC) for CO₂ adsorption application. First, we present the desired OPdAC characteristics and its precursors in terms of their chemical properties, elemental, and proximate compositions. This is followed by an overview of various activation methodologies and surface modification methods to attain the desired characteristics for CO₂ adsorption. Then the focus turned to present available OPdAC CO₂ adsorption performance and how it is affected by its physical and chemical characteristics. Based on these, we identify the challenges and the potential development in different aspects such as precursor selection, process development, and optimization of parameter. A pilot scale production cost analysis is also presented to compare various activation and surface modification methods, so that the appropriate method can be selected for CO₂ adsorption.

人为温室气体排放引起的环境二氧化碳（CO ₂）浓度增加，已导致全球陆地和海洋表面温度的增长率不断提高。为了缓解这一迫在眉睫的问题，人们建立了各种碳捕集与封存（CCS）技术。由于与传统的化学吸收不同，CO ₂吸附正变得日益重要，因为它不需要高能量消耗来进行溶剂再生和消耗腐蚀性化学溶剂。在CO ₂吸附中，活性炭显示出较高的CO ₂考虑到其发达的多孔结构的吸附能力。许多研究都将油棕废料用作低成本的前体。本文提供了迄今为止对可用于CO ₂吸附的油棕衍生活性炭（OPdAC）的研究工作的全面评估。首先，我们从化学性质，元素和附近的组成方面介绍了所需的OPdAC特性及其前体。接下来是对各种活化方法和表面改性方法的概述，以实现所需的CO ₂吸附特性。然后焦点转向提供可用的OPdAC CO ₂吸附性能以及它如何受到其物理和化学特性的影响。在此基础上，我们确定了不同方面的挑战和潜在发展，例如前体选择，工艺开发和参数优化。还提出了中试规模的生产成本分析，以比较各种活化方法和表面改性方法，以便可以为CO ₂吸附选择合适的方法。
