Latest Patents
Doyle's latest patents include a method of obtaining para-xylene, which discloses an improved technique for making and obtaining para-xylene from a mixture of xylene isomers. This method involves contacting a mixture of xylene isomers and ethylbenzene with a para-xylene selective adsorbent to yield a para-xylene depleted raffinate and a desorption effluent enriched with para-xylene. Notably, the method allows for isomerization without the need for pressurization, thus eliminating costly compression steps. Another significant patent focuses on para-xylene selective adsorbent compositions, which are designed for vapor-phase adsorption processes. These compositions are effective in separating para-xylene from mixed xylenes or Caromatic mixtures.
