摘要

摘要: 为实现园林废弃物科学处置并提高其资源化利用程度，研制了热解活化一体炉，将园林废弃物转变为热能与生物质活性炭，验证了园林废弃物热解同步活化处理提质的可行性。同时，研究了生物质活性炭对模拟烟气中SO₂的吸附能力。研究结果表明：热解同步活化技术可实现园林废弃物的高效处置与资源化利用，实现热-炭（活性炭）高质联产；活化后的生物质活性炭，碘值为550 mg/g，比表面积为245.94 m²/g，孔容为0.145 m³/g；以园林废弃物为原料制备的生物质活性炭的SO₂吸附容量为14.4 mg/g，达到了商品活性炭吸附容量65%。该研究可为园林废弃物高效处置、资源化利用以及热解同步活化技术的工程化推广提供参考。

Abstract: With the rapid development of urbanization in China， the huge production of garden waste in cities and towns has resulted in serious environmental pollution problems. In addition， recent treatment of garden waste is mainly focusing on incineration， which has an immediate and significant reduction effect， but is also a waste of biomass resources and unsustainable. Pyrolysis and activation are good options for resource utilization of garden waste. However， there is a lack of technical solutions to integrate pyrolysis with activation equipment to shorten the process flow and reduce the investment cost. In order to realize the scientific disposal of garden waste and improve its utilization， a pyrolysis-activation integrated furnace was developed to transform garden waste into heat and biomass-activated carbon， which verified the feasibility of the simultaneous treatment of pyrolysis and activation for garden waste. At the same time， the adsorption capacity of biomass-activated carbon on SO₂ in simulated flue gas was studied. The results showed that the simultaneous treatment of pyrolysis and activation could realize the efficient disposal and resource utilization of garden waste， and realize the high-quality cogeneration of heat-carbon （activated carbon）； the biomass activated carbon after activation had an iodine value of 550 mg/g， a specific surface area of 245.94 m²/g， and a pore volume of 0.145 m³/g； the biomass activated carbon prepared from garden waste had an adsorbing capacity on SO₂ of 14.4 mg/g， and that is 65% of the adsorption capacity of the commercial activated carbon. This study can provide a reference for the efficient disposal and resource utilization of garden waste， and the engineering promotion of simultaneous treatment of pyrolysis and activation.
