    摘要: Disclosed are antioxidants used in compositions and methods to stabilize synthetic feedstock derived from plastic. Some methods disclosed herein include adding an antioxidant composition to a plastic-derived synthetic feedstock composition. Some methods disclosed herein include heating plastic under substantially oxygen free conditions at a temperature of from about 400° C. to about 800° C. to produce a pyrolysis effluent, distilling the pyrolysis effluent, recovering the synthetic feedstock, and adding a stabilizer to the synthetic feedstock to reduce contamination. The disclosure also provides compositions including a synthetic feedstock derived from plastic and an antioxidant.

    摘要: Lubricity additives for hydrocarbon fuels are presented according to formula I:


    R1[(—O—R2)n-Q]p  (I)

    wherein p is 3 or greater; each n is independently selected from integers equal to 2 or greater; R1 is a C3-C20 aliphatic hydrocarbon group of valence p which is branched or linear and which is substituted or unsubstituted; each R2 is independently selected from C2-C20 divalent aliphatic or aromatic hydrocarbon groups which are branched or linear and which are substituted or unsubstituted; and each Q is independently selected from —NH2 or a moiety according to formula II:




    wherein each R3 is independently selected from C8-C60 alkenyl groups which are substituted or unsubstituted, providing that at least one Q is the moiety according to formula II.

    摘要: Disclosed are antifouling agents used in compositions and methods to reduce or prevent foulants in synthetic feedstocks derived from plastic. A method of reducing or preventing fouling in a plastic-derived synthetic feedstock composition may include adding an antifouling agent including a carboxylic acid anhydride or a copolymer of a dicarboxylic acid anhydride and alpha olefin to a synthetic feedstock composition derived from plastic pyrolysis containing a foulant to provide treated pyrolysate. The foulant may include, for example, nylon, polyvinyl chlorides, polyethylene terephthalate, polyamides, caprolactam, benzoic acid, phenol, p-cresol, dimethylphenol, isopropyl phenol, tert-butylphenol, dimethylethylphenol, napthalenol, varying lengths of alkenes and alkanes, propylene, tolune, pentene, butane, tetramethylindole, ethylbenzene, ethyldimethylpyrrole, dimethylfuran, tetrahydroquinoline, and any combination thereof.

    摘要: Disclosed are extraction solvents used in compositions and methods to refine synthetic feedstocks derived from plastic. Methods of refining plastic-derived synthetic feedstocks are also provided. For example, a method of refining a plastic-derived synthetic feedstock composition may include adding an extraction solvent to a synthetic feedstock composition derived from plastic pyrolyis to provide an extract phase and a raffinate phase, wherein the extraction solvent includes a polar organic extraction solvent immiscible in the synthetic feedstock. The methods may also include separating the raffinate phase from the extract phase to obtain a refined synthetic feedstock.
