Abstract[English]
A process to reduce siloxanes in a waste plastic pyrolysis oil composition is disclosed. The process can include contacting the waste plastic pyrolysis oil composition with a modified silica gel composition under conditions sufficient to produce a purified waste plastic pyrolysis oil composition. The purified waste plastic pyrolysis oil composition can have at least 50% by weight less siloxanes, preferably at least 60% by weight less siloxanes, as compared to the untreated waste plastic pyrolysis oil composition. The siloxanes can include acyclic siloxanes, cyclic siloxanes, or a combination thereof. The modified silica gel composition can include cobalt or iron compositions.[French]
Est divulgué ici un procédé de réduction de siloxanes dans une composition d'huile de pyrolyse de déchets plastiques. Le procédé peut comprendre la mise en contact de la composition d'huile de pyrolyse de déchets plastiques avec une composition de gel de silice modifiée dans des conditions suffisantes pour produire une composition d'huile de pyrolyse de déchets plastiques purifiée. La composition d'huile de pyrolyse de déchets plastiques purifiée peut présenter au moins 50 % en poids de moins de siloxanes, de préférence au moins 60 % en poids de moins de siloxanes, par rapport à la composition d'huile de pyrolyse de déchets plastiques non traitée. Les siloxanes peuvent comprendre des siloxanes acycliques, des siloxanes cycliques ou une combinaison de ceux-ci. La composition de gel de silice modifiée peut comprendre des compositions de cobalt ou de fer.
