等离子体气化是一种创新技术，通过热等离子体将高热量废物流转化为有价值的合成气和玻璃化炉渣。建立了等离子体气化的可行性及对环境影响的试验方案。选择来自地毯和纺织品废料的RDF（垃圾衍生燃料）作为半中试气化试验的进料。测试的目的是：（1）评价制备稳定合成气的技术可行性;（2）表征该合成气的组成;（3）确定用于纯化合成气的合适的后处理配置和（4）表征炉渣的稳定性，即，它的抗浸出性可用作二级建筑材料。试验表明，等离子体气化可以产生合适的合成气质量和炉渣，其特征在于可接受的可熔化性。根据测试结果，将准备进一步扩大这一技术的规模，并进行验证测试。
Plasma gasification is an innovative technology for transforming high calorific waste streams into a valuable synthesis gas and a vitrified slag by means of a thermal plasma. A test program has been set up to evaluate the feasibility of plasma gasification and the impact of this process on the environment. RDF (refuse derived fuel) from carpet and textile waste was selected as feed material for semi-pilot gasification tests. The aim of the tests was: (1) to evaluate the technical feasibility of making a stable synthesis gas; (2) to characterize the composition of this synthesis gas; (3) to define a suitable after-treatment configuration for purification of the syngas and (4) to characterize the stability of the slag, i.e., its resistance to leaching for use as a secondary building material. The tests illustrate that plasma gasification can result in a suitable syngas quality and a slag, characterized by an acceptable leachability. Based on the test results, a further scale-up of this technology will be prepared and validation tests run.
