A process is provided of treating a feed comprising polyethylene terephthalate comprising dissolving said feed in a polar solvent at a temperature between about 100 to 250&#xb0; C. to produce a dissolved feed; then adding an anti-solvent that is less polar than said polar solvent followed by cooling a resulting mixture resulting in precipitation of purified polyethylene terephthalate and then separation of solid purified polyethylene terephthalate from remaining liquids.

Processes and apparatuses for producing para-xylenes are provided. The processes comprises providing a reformate stream comprising aromatic hydrocarbons to a reformate splitter to provide a reformate bottoms stream and a reformate overhead stream. A portion of the reformate bottoms stream is passed to a para-xylene separation unit for separating para-xylene, wherein the portion of the reformate bottoms stream is passed to the para-xyelene separation unit without an intermediate step for removal of olefins.

Isomerization processes such as the isomerization of ethylbenzene and xylenes, are catalyzed by the new crystalline aluminosilicate zeolite comprising a novel framework type that has been designated UZM-55. This zeolite is represented by the empirical formula:MRAlESiOwhere M represents a metal or metals selected from zinc or Group 1 (IUPAC 1), Group 2 (IUPAC 2), Group 3 (IUPAC 3) or the lanthanide series of the periodic table including sodium, potassium or a combination of sodium and potassium cations, R is an organic structure directing agent or agents derived from reactants R1 and R2 such as where R1 is diisopropanolamine and R2 is a chelating diamine, and E is an element selected from the group consisting of gallium, iron, boron and mixtures thereof. Catalysts made from UZM-55 have utility in various hydrocarbon conversion reactions.
