Die entsprechenden Versuche werden in einem Top Blown Rotary Converter (TBRC) im Versuchs- und im Demonstrationsma\u00dfstab durchgef\u00fchrt. Die effiziente Koagulation w\u00e4hrend des Recyclingprozesses wird anhand unterschiedlicher Salzmischungen untersucht. Zudem erfolgt die Evaluierung von einer thermischen Behandlung von organisch behaftetem Material. Diese dient der Entwicklung eines optimalen Prozesses als Kombination aus Vorbehandlung und Recycling.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Des Weiteren werden von der Arbeitsgruppe Untersuchungen bez\u00fcglich der Reinheit der Schmelze unter Anwendung verschiedener Entfernungs- und Detektionstechniken durchgef\u00fchrt, um die hohen Anforderungen an die Produkt- und Materialeigenschaften erf\u00fcllen zu k\u00f6nnen. Bez\u00fcglich des Partikelverhaltens in Schmelzen, wie beispielsweise das Agglomerations- und Absetzverhalten, wird weiterhin Grundlagenforschung betrieben, um den Kenntnisstand \u00fcber Partikel zu erweitern. Die wesentlichen Ziele der Arbeit liegen in der Verbesserung bestehender Technologien und dem Verst\u00e4ndnis der vorliegenden Mechanismen.<\/p>\n\n\n\n<div class=\"wp-block-stackable-columns stk-block-columns stk-block stk-a7b143f\" data-block-id=\"a7b143f\"><div class=\"stk-row stk-inner-blocks stk-block-content stk-content-align stk-a7b143f-column\">\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-46d9d54\" data-v=\"4\" data-block-id=\"46d9d54\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-46d9d54-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-46d9d54-inner-blocks\">\n<p class=\"wp-block-paragraph\"><strong>Kontakt:<\/strong><\/p>\n<\/div><\/div><\/div>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-efd7c0a\" data-v=\"4\" data-block-id=\"efd7c0a\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-efd7c0a-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-efd7c0a-inner-blocks\">\n<p class=\"wp-block-paragraph\"><strong>Alumni:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\" data-block-type=\"core\">\n<li data-block-type=\"core\"><a href=\"\/de\/team\/alumni\/cong-li\/\">Dr.-Ing.
