Mikrowellenpyrolyse von carbonfaserhaltigen Kunststoffen als Recyclingoption

Abstract: Herausforderungen bei der Etablierung einer Circular Economy von carbonfaservertärkten Kunststoffen (CFK) ergeben sich insbesondere durch die nötige, jedoch problematische Trennung des Faser‐Matrix‐Verbunds. Das Pyrolyseverfahren stellt eine mögliche, bereits industriell umgesetzte, Technologie zur Verbundtrennung dar. Eine Weiterentwicklung ist die mikrowellenunterstütze Pyrolyse, bei der das CFK‐Material durch die Mikrowellen aufgeheizt und so die Faser freigelegt wird. Prozessgrundlagen und Einflüsse auf di… Show more

“…Their use for knowledgebased engineering of surface-reactive systems [11,12], however, is currently hindered by the high computational cost [9,10,13,14] associated with the detailed chemical kinetics on the catalyst scale. Even if the timescales of surface reactions and the gas phase are separated via the steady-state approximation [10,[15][16][17][18], the surface kinetics pose a severe computational bottleneck [9,10,13,[19][20][21]. Therefore, there is huge interest in accelerating the kinetic calculations [9,10,22,23].…”

“…To this end, steady-state solutions of surface kinetics are usually mapped in a tabulation approach. The in-situ adaptive tabulation [13,19,21,22,[24][25][26] builds such a map during the simulation by exploiting prior solutions to estimate new queries. In contrast, surrogate models like splines or the (error-based modified) Shepard interpolation approach map precomputed solutions to accelerate reactor simulations [2, 15,16,18,20,[27][28][29][30][31] or even spatial subsystems of the reactor [32,33] and breakthrough curves [34].…”
