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： 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.

摘要： A system for polishing an outer surface of a specimen, the system including a motor and a rotatable shaft extending from a first end of the motor, wherein the specimen is removably attachable to the rotatable shaft, a safety cover configured to at least partially surround at least a portion of the rotatable shaft, wherein the safety cover includes a top panel, a first side panel and a second side panel spaced from each other across a width of the safety cover and extending downwardly from the top panel, and at least one aperture extending through at least one of the first and second side panels. The system further includes an abrasive material insertable through the at least one aperture so that the abrasive material is positionable to contact the outer surface of the specimen.

摘要： Lubricity additives for hydrocarbon fuels are provided according to formula I:
wherein n is 1 or 0; each Q is independently selected from oxygen and sulfur; each R is independently selected from C8-C60 alkenyl groups which are substituted or unsubstituted; and L is a linking group comprising 0-20 carbons which may be substituted or unsubstituted and may optionally comprise catenary heteroatoms. Fuel mixtures comprising a hydrocarbon fuel; and a lubricity additive according to the present disclosure are also provided. Methods of making lubricity additives comprise reacting an alkenyl succinic anhydrides (ASA's) with certain bisamides or bisthioamides.
