摘要： 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.

摘要： Systems and methods are provided for reducing or minimizing the chloride content of products generated during co-processing of a plastic feedstock (such as plastic waste) in a refinery process. The reduction in chloride is achieved by mixing the plastic feedstock with one or more additional feedstocks for co-processing in a mixing and/or holding vessel that is maintained at a dechlorination temperature that allows for decomposition of chlorine from the plastic feedstock to form HCl, while reducing or minimizing other conversion of the plastic feedstock and/or the additional feedstock. A purge gas can be passed through the mixing/holding vessel to remove the evolved HCl from the vessel. Because the dechlorination temperature is selected to reduce or minimize conversion of the feedstocks in the mixture, the amount of carbon-containing products that are removed with the purge gas can be reduced or minimized. The dechlorinated mixture of plastic feedstock and additional feedstock(s) can then be processed in a convenient refinery process, such as a thermal cracking process (e.g., coking, visbreaking, other types of pyrolysis) or a catalytic conversion process (e.g., fluid catalytic cracking).

摘要： 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.
