Résumé
In the present study, catalytic fast pyrolysis of waste mixed cloth in an ex-situ method using hierarchical HZSM and commercial CaO was investigated. Pyrolysis of waste mixed cloth in a temperature range of 450 °C to 750 °C mainly allowed for the formation of levoglucosan without any catalysts. The utilization of HZSM with Brønsted/Lewis acid sites on micro- and mesoporous structures significantly contributed to monocyclic/dicyclic chemicals production, mainly referring to monoaromatics and naphthalene-based derivatives, especially in the case of high heating rates and catalyst usages. Furthermore, CaO revealed strong deoxygenation performance for the transformation of waste mixed cloth into low oxygen-containing chemicals, such as ketones, aliphatic hydrocarbons and aromatics. The present research thus highlights a feasible route for the catalytic upgrading of waste mixed cloth into some kinds of value-added chemicals.
