  • Patent number: 12258528
    Abstract: A method of producing diesel from municipal solid waste (MSW and Tire Waste) without Fischer-Tropsch synthesis, the method includes sorting waste feedstock into conforming waste capable of being converted into hydrogen-rich gas. The conforming waste is then conditioned into a specific recipe of moisture, cellulose, and/or hydrocarbons, resulting in sized fluff. Upon testing and meeting a standard for elemental composition, the fluff is then pelletized to form a very dense, high-BTU-rich, consistent solid fuel feedstock. The solid fuel pellets are then processed thermally in a high-temperature pyrolysis system which converts the solid fuel into a hydrogen-rich fuel gas. The fuel gas is reconstituted, converting it into a liquid ULSD fuel. The liquid fuel is then further analyzed and upgraded into fully compliant renewable diesel fuel and other valuable byproducts.

  • Patent number: 12258530
    Abstract: Alkylated naphthalene compositions are usually formed by reacting naphthalene with an electrophilic agent under acid-catalyzed conditions to afford a mixture of monoalkylated naphthalenes, dialkylated naphthalenes, and sometimes polyalkylated naphthalenes. Reaction conditions are usually chosen to change the product distribution for purposes of modifying lubricant properties such as viscosity or volatility. Rarely does the product distribution exceed 90 wt. % monoalkylated naphthalenes. Viscosity and volatility may alternately be modified by obtaining a first fraction enriched in monoalkylated naphthalenes and a second fraction enriched in dialkylated naphthalenes and combining the first fraction and the second fraction in a specified ratio to produce a modified alkylated naphthalene composition having a targeted value of one of the viscosity or the volatility.

  • Patent number: 12195677
    Abstract: A method of hydroprocessing is performed wherein non-petroleum feedstocks, such as those containing from about 10% or more olefinic compounds or heteroatom contaminants by weight, are treated in a first reaction zone to provide reaction products. The process involves introducing the feedstock along with diluents or a recycle and hydrogen in a first reaction zone and allowing the feed and hydrogen to react in a liquid phase within the first reaction zone to produce reaction products. The reaction products are cooled and/or water is removed from the reaction products. At least a portion of the cooled and/or separated reaction product are introduced as a feed along with hydrogen into a second reaction zone containing a hydroprocessing catalyst. The feed and hydrogen are allowed to react in a liquid phase within the second reaction zone to produce a second-reaction-zone reaction product.
