摘要： 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° 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.

摘要： A process for converting pyrolysis effluent stream into hydrocarbon products. Waste plastics are pyrolyzed at high temperature in a pyrolysis reactor to obtain a plastic pyrolysis effluent stream. The plastic pyrolysis effluent stream is further sent to a steam cracking unit for the separation of plastic pyrolysis effluent stream into a C5+ hydrocarbon stream and a C4 hydrocarbon stream. The pyrolysis reactor is operated at a to obtain hydrocarbon products of high value.

摘要： A plastic pyrolysis process produces light olefin product and heavier products. The light olefin products are separated in a recovery process while the heavier product can be sent to a cracking unit to be further cracked to desired products. The cracked effluent stream may be subjected to the recovery process along with the light olefin product.
