生物质活性炭的制备、应用及再生利用研究进展

Research progress on preparation,application and regeneration of biomass-based activated carbon

综述了生物质活性炭的制备、应用以及再生方法,生物质活性炭因其发达的孔隙结构、高比表面积、理化性质稳定和较强的吸附性能而被广泛应用于化工、储能和催化领域。近年来研究学者在不同的领域对其进行了深入的探讨,不断取得新的进展,大部分研究成果表明,高品质生物质活性炭的低成本、高效制备以及废弃活性炭的再生是限制其工业应用的关键因素。但由于生物质自身具有密度较低、无粘结性等缺点,导致生物质基活性炭的强度较差,因此制备出高强度生物质基活性炭是今后的重点研究方向。

This article summarizes biomass activated carbon preparation,application and regeneration methods,biomass-based activated carbon was widely used in the areas of chemical,energy storage and catalysis with its’developed pore structure,high specific surface area,stable physic-chemical properties and strong adsorbability.In recent years,researchers have conducted in-depth discussions on it in different fields,and new progress has been made constantly.Most of the research results show that the production of biomass-based activated with low cost and high efficiency and the regeneration of waste activated carbon were the key factors limiting its industrial application.However,due to the low density of biomass itself,non-bonding and other shortcomings,leading to poor strength of biomass-based activated carbon,so the preparation of high-strength biomass-based activated carbon is the key research direction in the future.
