摘要:
The present invention relates to a process for producing BTX comprising pyrolysis, aromatic ring opening and BTX recovery. Furthermore, the present invention relates to a process installation to convert a pyrolysis feedstream into BTX comprising a pyrolysis unit, an aromatic ring opening unit and a BTX recovery unit.
摘要:
A process for producing olefins from oxygenates comprises the following steps: (i) heterogeneously catalyzed conversion of at least one oxygenate to an entire stream containing propylene, aromatics and cyclic olefins; (ii) olefin interconversion of at least a part of the entire stream; (iii) separation of a stream rich in aromatics from the reaction product of the olefin interconversion; and (iv) hydrogenation of the stream rich in aromatics.
