摘要： Disclosed are pour point depressants used in compositions and methods for achieving the cold flow properties of synthetic feedstock derived from plastic. A method of obtaining the synthetic feedstock is also disclosed, which includes heating plastic under substantially oxygen free conditions at a temperature of from about 400° C. to about 850° C. to produce a pyrolysis effluent, condensing the heated a pyrolysis effluent to obtain a synthetic feedstock, recovering the synthetic feedstock, and adding a pour point depressant to the synthetic feedstock to lower the pour point.

摘要： The present disclosure relates to various testing methods that can be applied to oils, such as pyrolysis oils. Different testing methods can be used to determine the oxidative stability of an oil. The testing methods may also be used to differentiate between various oils and to determine the effectiveness of various antioxidants on the oxidative stability of an oil.

摘要： Disclosed are antifouling agents used in compositions and methods to reduce or prevent foulants in synthetic feedstocks derived from plastic. Also disclosed is pyrolysis process equipment treated with an antifouling agent. 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.

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.
