报废汽车破碎残余物（ASR）催化气化机理及其资源化应用基础研究

我国未来几年汽车报废量将迎来暴发性增长。不断提高的回收利用法规要求和规模化的报废汽车回收利用产业，必然要采用大规模机械化拆解、破碎、分选装备，由此将产生大量汽车破碎残余物（ASR），从而影响我国报废汽车回收利用率的提高。因此，对于ASR资源化和能源化方面的研究亟待开展。.在前一项科学基金项目研究工作的基础上，针对ASR热裂解和气化反应不充分、可燃性气体产物热值低、环境负荷物质的转化机制尚不清晰等问题，通过研究和制备ASR气化反应催化剂、设计开发连续式催化气化试验装置、探讨ASR催化气化反应动力学机制和催化剂失活模型、制定和优化ASR催化气化工艺，提高可燃性合成气及氢气的转化率，进而提升热值，为ASR的能源化提供基础理论支持。通过研究和分析ASR催化气化过程中环境负荷物质的转化、消除机理，探讨重金属的固定机制，为扩大ASR的资源化应用提供基础理论和方法支持。

Within next few years, China will inevitably see the outbreak growth of scrap automobiles volume in community. With increasing regulatory requirements and rapid developing of End-of-Life Vehicles recycling industry, it will popular to adopt large-scale dismantling, shredding, and sorting facilities in the process of End-of-Life Vehicles; therefore, it is necessary to carry out the fundamental research on the recycling and energy recovery of automotive shredder residues (ASR)..On the basis of the previous research work, which is supported by NSFC project, the scientific issues such as, ASR pyrolysis/gasification reaction is insufficient, the low calorific value of combustible gas product, the elimination mechanism of environmentally hazardous substances is not yet clear, will be addressed in this project. The following research works will be implementation such as, preparation and characterization of ASR gasification reaction catalyst, design and development of a continuous catalytic gasification test equipment, investigation of the ASR catalytic gasification kinetics and mechanisms and catalyst deactivation model, development and optimization of ASR catalytic gasification process to improve the conversion rate of flammable syngas and hydrogen, and thus enhance the calorific value, and provide the basis for theoretical support for ASR energy recovery. The transformation and elimination mechanism of environmentally hazardous substances through ASR catalytic gasification process will be investigated, and meanwhile, the immobilization effects of heavy metals in solid residue will also be addressed in this project, to provide generic theories and technologies to support the extensive application of ASR recycling..The research project will provide new strategies and new ideas for carrying out eco-design and promoting recovery rate of automotive products in China.
