In the field of waste management, thermal disposal is a treatment option able to recover resources from "end of life" products. Pyrolysis and gasification are emerging thermal treatments that work under less drastic conditions in comparison with classic direct combustion, providing for reduced gaseous emissions of heavy metals. Moreover, they allow better recovery efficiency since the process by-products can be used as fuels (gas, oils), for both conventional (classic engines and heaters) and high efficiency apparatus (gas turbines and fuel cells), or alternatively as chemical sources or as raw materials for other processes. This paper presents a comparative study of a steam gasification process applied to three different waste types (refuse-derived fuel, poplar wood and scrap tyres), with the aim of comparing the corresponding yields and product compositions and exploring the most valuable uses of the by-products.
在废物管理领域，热处置是一种能够从“寿命终结”产品中回收资源的处理方式。热解和气化是新兴的热处理方法，与传统的直接燃烧相比，它们在较温和的条件下运行，可减少重金属的气态排放。此外，它们具有更高的回收效率，因为工艺副产品可作为燃料（气体、油类）用于传统设备（传统发动机和加热器）和高效设备（燃气轮机和燃料电池），或者用作化学原料或其他工艺的原材料。本文对应用于三种不同废物类型（垃圾衍生燃料、杨树和废旧轮胎）的蒸汽气化过程进行了比较研究，目的是比较相应的产量和产物组成，并探索副产品最有价值的用途。
