Patents by Inventor Michael S. Allegro, II

Michael S. Allegro, II has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Conversion of plastics to monomers with integrated recovery with a cracking unit
    Patent number: 12012553
    Abstract: 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.
    Type: Grant

  • Integrated process for pyrolysis and steam cracking
    Patent number: 11572511
    Abstract: 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.

  • CONVERSION OF PLASTICS TO MONOMERS BY INTEGRATION OF LOW-TEMPERATURE AND HIGH-TEMPERATURE PYROLYSIS
    Publication number: 20220010217
    Abstract: A plastic pyrolysis process that can produce high yields of ethylene, propylene and other light olefins from waste plastics is disclosed. The plastic feed is pyrolyzed at a low-temperature pyrolysis process and subsequently pyrolyzed in a high-temperature pyrolysis process directly to monomers, such as ethylene and propylene. Insufficiently pyrolyzed product from the low-temperature pyrolysis process can be fed to the high-temperature pyrolysis process while preserving the desired low-temperature product monomers.
