Propylene production

   
   

A method for making propylene from alpha olefins, internal linear olefins and isoolefins wherein the alpha olefins are subjected to a combination of hydrogenation and double bond isomerization to form additional internal linear olefins, the internal linear olefins are separated from the isoolefins and disproportionated with ethylene to form a propylene product, while the thus separated isoolefins are subjected to skeletal isomerization to form yet additional internal linear olefins to be converted into yet additional propylene product.

Um método para fazer o propylene dos olefins do alfa, dos olefins lineares internos e dos isoolefins wherein os olefins do alfa são sujeitados a uma combinação do hydrogenation e do isomerization da ligação dobro para dar forma a olefins lineares internos adicionais, os olefins lineares internos está separado dos isoolefins e desproporcional com etileno para dar forma a um produto do propylene, quando os isoolefins assim separados forem sujeitados ao isomerization esqueletal ao formulário contudo aos olefins lineares internos adicionais a ser convertidos em contudo ao produto adicional do propylene.
