    Abstract: A process for producing para-xylene (PX) comprises supplying a hydrocarbon feed comprising xylenes and ethylbenzene (EB) to a PX recovery unit, where a PX-rich stream and at least one PX-depleted stream are recovered from the feed. The PX-depleted stream is then separated into an EB-rich stream and an EB-depleted stream in a divided wall column. The EB-depleted stream is then isomerized under at least partial liquid phase conditions to produce a first isomerized stream having a higher PX concentration than the PX-depleted stream, and the EB-rich stream is isomerized under at least partial vapor phase conditions to produce a second isomerized stream having a higher PX concentration than the PX-depleted stream. The first and second isomerized streams are then recycled to the PX recovery unit to recover additional PX and the process is repeated to define a so-called xylene isomerization loop.

    Abstract: A method for producing hydrocarbon products is proposed which comprises providing a C4 hydrocarbon stream (C4) that predominantly comprises branched and unbranched hydrocarbons each having four carbon atoms, and an n-C4 partial stream (n-C4), which predominantly comprises unbranched hydrocarbons with four carbon atoms and an iso-C4 partial stream (i-C4) which predominantly comprises branched hydrocarbons with four carbon atoms, from the C4 hydrocarbon stream (C4) or a stream derived therefrom. It is envisaged that at least part of the n-C4 partial stream (n-C4) or a stream derived therefrom should be cracked at a cracking severity at which not more than 92% of n-butane contained in the n-C4 partial stream (n-C4) or in the derived stream is converted.
