  • Patent number: 11873451
    Abstract: Compositions based on effluents and/or products from FCC processing of a high saturate content, low heteroatom content feedstock are provided. By processing a high saturate content, low heteroatom content feed under various types of FCC conditions, a variety of compositions with unexpected compositional features and/or unexpected properties can be formed. The unexpected compositional features and/or unexpected properties can correspond to features and/or properties associated with one or more of the total effluent, a naphtha boiling range portion of effluent, a distillate or light cycle oil boiling range portion of the effluent, and/or a bottoms portion of the effluent.
    Type: Grant

  • Publication number: 20240010939
    Abstract: Provided herein is a method for producing a hydrocarbon fluid from waste plastic feedstock, comprising (a) providing a first hydrocarbon feed stream, wherein at least 50 wt % off said first hydrocarbon feed stream is obtained from pyrolysis of plastic waste; (b) removing contaminants from said first hydrocarbon feed stream using a washing step with a polar solvent and/or contacting the stream with one or more adsorbents; thereby obtaining a first hydrocarbon fluid; and (c) hydrogenation of olefins and diolefins in said first hydrocarbon fluid; thereby obtaining a hydroprocessed hydrocarbon fluid containing less than 0.1 wt % olefins; a total amount of Nmetals selected from mercury, lead, and iron below 5 wppm; less than 5 wppm of chlorine and fluorine; and less than 5 wppm of sulfur.

  • Publication number: 20230382818
    Abstract: A method for producing a higher alcohol from a waste plastic feedstock is disclosed, comprising: (a) providing a hydrocarbon feed stream comprising a pyrolysis oil feed obtained from pyrolysis of plastic waste, wherein the pyrolysis oil comprises at least 20 wt % higher olefins with a carbon number in the range C5-C20, based on its total hydrocarbon content; (b) contacting the hydrocarbon feed stream with synthesis gas under hydroformylation conditions in the presence of a hydroformylation catalyst and recovering a hydroformylation product; (c) subjecting the hydroformylation product to hydrogenation and/or a distillation to recover a higher alcohol product.
