  • Publication number: 20240158698
    Abstract: A process for converting solid plastic waste to hydrocarbon oil includes melting a feed comprising solid plastic waste to produce a liquefied plastic stream and visbreaking the liquefied plastic stream in a visbreaker unit having a visbreaker furnace and a soaker vessel. Visbreaking includes heating the liquefied plastic stream in the visbreaker furnace to produce a heated liquefied plastic stream, maintaining the heated liquefied plastic stream at the reaction temperature in the soaker vessel for a residence time to produce a visbreaker effluent, and injecting a stripping gas into the soaker vessel. The stripping gas includes at least one of steam, nitrogen, helium, argon, or combinations of these. The process includes introducing the stripping gas to the liquefied plastic stream upstream of the visbreaker furnace, the heated liquefied plastic stream downstream of the visbreaker furnace, or both. The visbreaker effluent is separated to produce a liquid hydrocarbon oil.

  • Patent number: 9925284
    Abstract: The present invention relates to a nanoparticle having a linker connected to a long alkane or alkene chain, and a method for preparing the nanoparticle. The alkyl chain of C10-30 introduced with a ligand of the present invention can be coated on a hydrophobic nanoparticle through a noncovalent bond, enabling easy introduction of various ligands to the nanoparticle, and the nanoparticle having various functional groups prepared using the method can be applied to fluorescent detection, MRI, raman spectroscopy, optical detection, PET, SPECT, or gamma image device, and the ligand of the visualization agents can be modified to be used for new vessels detection, cancer cell detection, immunocyte detection, hepatocyte detection, cell death detection, and gene detection.
