Abstract

Biomass can be converted into energy, fuels, and value-added products by adopting proper conversion or production methods. For many years, biomass has been considered to be a good candidate for producing biochar or activated carbon. The awareness created on mitigation of carbon dioxide (CO2), which is the major cause of global warming, necessitated developing potential methods and materials for curbing CO2 originating from various sources. Adsorption is the most viable option to mitigate CO2 by using activated carbon which can be derived from various biomass sources. In recent years, activated carbon has been produced from different biomass substances by varying carbonization and activation duration, carbonization and activation temperature, impregnation ratio, and the concentration of the activating agent to improve its surface area and porosity. This review article provides a comprehensive review on utilization, production and characterization of biomass-based activated carbon for CO2 adsorption. Initially, the article discusses the review of research works carried out on utilization of biomass-based activated carbon for CO2 adsorption. Furthermore, the article presents the research works carried out on surface textural characteristics, physicochemical properties, and maximum adsorption capacity of activated carbon obtained from different biomass substances. Finally, the article presents the research works carried out related to the biomass-based activated carbon and the parameters significantly enhancing the CO2 adsorption performance.

生物质活性炭对CO2的吸附研究进展

通过采用适当的转化或生产方法，生物质可以转化为能源、燃料和增值产品。多年来，生物质一直被认为是生产生物炭或活性炭的良好候选材料。二氧化碳是全球变暖的主要原因，随着人们对减少二氧化碳的认识的提高，有必要开发抑制各种来源的二氧化碳的潜在方法和材料。吸附是最可行的选择，以减少二氧化碳通过使用活性炭，可以从各种生物质来源。近年来，利用不同的生物质物质，通过改变炭化活化时间、炭化活化温度、浸渍比、活化剂浓度等方法来提高活性炭的比表面积和孔隙率。本文综述了生物质基活性炭在CO2吸附方面的研究进展。本文首先对生物质活性炭吸附CO2的研究进展进行了综述。介绍了不同生物质原料制备的活性炭的表面结构特征、理化性质和最大吸附量等方面的研究工作。最后，介绍了生物质基活性炭的相关研究工作和显著提高CO2吸附性能的参数。

期刊介绍： Energy & Environment is an interdisciplinary journal inviting energy policy analysts, natural scientists and engineers, as well as lawyers and economists to contribute to mutual understanding and learning, believing that better communication between experts will enhance the quality of policy, advance social well-being and help to reduce conflict. The journal encourages dialogue between the social sciences as energy demand and supply are observed and analysed with reference to politics of policy-making and implementation. The rapidly evolving social and environmental impacts of energy supply, transport, production and use at all levels require contribution from many disciplines if policy is to be effective. In particular E & E invite contributions from the study of policy delivery, ultimately more important than policy formation. The geopolitics of energy are also important, as are the impacts of environmental regulations and advancing technologies on national and local politics, and even global energy politics. Energy & Environment is a forum for constructive, professional information sharing, as well as debate across disciplines and professions, including the financial sector. Mathematical articles are outside the scope of Energy & Environment. The broader policy implications of submitted research should be addressed and environmental implications, not just emission quantities, be discussed with reference to scientific assumptions. This applies especially to technical papers based on arguments suggested by other disciplines, funding bodies or directly by policy-makers.
