  • CIRCULAR CHEMICALS OR POLYMERS FROM PYROLYZED PLASTIC WASTE AND THE USE OF MASS BALANCE ACCOUNTING TO ALLOW FOR CREDITING THE RESULTANT PRODUCTS AS CIRCULAR
    Publication number: 20230016550
    Abstract: This disclosure relates to the production of chemicals and plastics using pyrolysis oil from the pyrolysis of plastic waste as a co-feedstock along with a petroleum-based, fossil fuel-based, or bio-based feedstock. In an aspect, the polymers and chemicals produced according to this disclosure can be certified under International Sustainability and Carbon Certification (ISCC) provisions as circular polymers and chemicals at any point along complex chemical reaction pathways. The use of a mass balance approach which attributes the pounds of pyrolyzed plastic products derived from pyrolysis oil to any output stream of a given unit has been developed, which permits ISCC certification agency approval.

  • Alkylated 1,3-benzenediamine compounds and methods for producing same
    Patent number: 8563489
    Abstract: An alkylated 1,3-benzenediamine compound used as a deposit-control lubricant additives for organic materials including lubricating oil, gasoline, and diesel fuels. The invention improves the oxidative stability of the lubricants and fuels by adding the alkylated 1,3-benzenediamine compound. The alkylated 1,3-benzenediamine compound is formed using a catalytic hydrogenation that alkylates the 4 and/or 6 position of the central aromatic ring.
