A gasification pilot plant was built up in order to investigate the influence of both feedstock type and co‐gasification on the distribution and composition of the products. The results showed that at the same process condition, different feedstocks could result in different product yields. For instance, the highest gas yield was obtained from tire gasification, while the lowest one belonged to weed gasification. The characterization of the products showed the presence of different components and functionalities in the samples produced. In addition, the co‐gasification of the feedstocks resulted in the products with different specifications than single feeding, proving the existence of different reaction pathways. This means that feedstocks and their derivatives could interact with each other and resulted in nonproportional yields and composition for the char, tar, and gaseous products in comparison with the products from the gasification of the single feedstocks. As an example, the tar from co‐gasification had a lower content of acids but a higher content of amines and amides. This confirmed that co‐gasification influenced the reaction network significantly, impacting the formation of gases, tar, and char, originated from the cross‐interaction among the reaction intermediates derived from the pyrolysis/gasification of the various feedstocks.

废物的气化：原料类型和共气化对挥发物和焦炭形成的影响

为了研究原料类型和共气化对产品分布和组成的影响，建立了一个气化试验工厂。结果表明，在相同的工艺条件下，不同的原料可能导致不同的产品收率。例如，最高的气体产量来自轮胎的气化，而最低的是杂草气化。产品的表征表明所生产的样品中存在不同的组分和功能。此外，原料的共气化导致产品的规格与单次进料不同，证明存在不同的反应路径。这意味着原料和它们的衍生物可能相互相互作用，与焦化单一原料的产物相比，焦炭，焦油和气态产物的产率和组成不成比例。例如，共气化焦油的酸含量较低，但胺和酰胺含量较高。这证实了共气化显着影响了反应网络，影响了气体，焦油和焦炭的形成，这是由各种原料的热解/气化衍生的反应中间体之间的交叉相互作用所致。共气化的焦油中酸含量较低，但胺和酰胺含量较高。这证实了共气化显着影响了反应网络，影响了气体，焦油和焦炭的形成，这是由各种原料的热解/气化衍生的反应中间体之间的交叉作用所致。共气化的焦油中酸含量较低，但胺和酰胺含量较高。这证实了共气化显着影响了反应网络，影响了气体，焦油和焦炭的形成，这是由各种原料的热解/气化衍生的反应中间体之间的交叉作用所致。
