Abstract: A method of processing a plastic and a method of processing pyoil derived from a plastic. A numerical model for a correlation between chlorine content in one or more process streams of a steam cracking unit and a hydrocarbon to steam ratio in a feed stream of the steam cracking unit is constructed. A pyoil and naphtha blend is mixed with steam at a hydrocarbon to steam ratio obtain from the model to produce the feed stream for a steam cracking unit. The feed stream is processed in the steam cracking unit to produce olefins.

Abstract: The invention relates to the synthesis of tetraphenol-substituted structures, in particular meta-substituted xylenes. Said tetraphenol-type structures are reacted to obtain organic phosphorus compounds, in particular organophosphites. The invention further relates to the production of catalytically active compositions which contain transition metals in addition to the aforementioned organic phosphorus compounds. According to another subject matter of the invention, said catalytically active compositions are used in chemical reactions with small molecules, e.g. HCN, CO, hydrogen, and amines.
