摘要： Provided is a method of producing dechlorinated waste plastic pyrolysis oil. The method includes (S1) putting a waste plastic feedstock containing moisture into a reactor; (S2) pyrolyzing the waste plastic feedstock by heating the reactor to a target temperature Tf at a heating rate R1 of 2° C./min or less; and (S3) recovering pyrolysis oil pyrolyzed in the reactor. Step (S2) includes one or more temperature plateaus in which a predetermined temperature T1 is maintained at a temperature of 100° C. or higher for a predetermined time.

摘要： The present disclosure provides a method and device for refining waste plastic pyrolysis oil, the method including (S1) subjecting a waste plastic pyrolysis oil feedstock to a heat treatment by charging the waste plastic pyrolysis oil feedstock into a rotary kiln reactor and increasing a temperature of the rotary kiln reactor to form a product; (S2) recovering a gas component from the product of step (S1); (S3) separating a high boiling point wax component from the recovered gas component and re-supplying the separated high boiling point wax component to the rotary kiln reactor in step (S1); and (S4) recovering refined oil from the gas component from which the high boiling point wax component is removed.

摘要： A cathode active material for a lithium secondary battery includes a lithium metal oxide particle and a thio-based compound formed on at least portion of a surface of the lithium metal oxide particle. The thio-based compound has a double bond that contains a sulfur atom. Chemical stability of the lithium metal oxide particle may be improved and surface residues may be reduced by the thio-based compound.

摘要： Provided are a polyamideimide film, a window cover film, and a display panel including the same. More specifically, a polyamideimide film including an amideimide structure derived from a dianhydride, a diamine, and an aromatic diacid dichloride is provided, wherein a chlorine content in the film is 5 to 33 ppm and a yellow index change amount ΔYI is 5 or less, the yellow index change amount being measured in accordance with ASTM E313 after repeating a process of irradiating 0.55 W/m2 of UVA at 340 nm at 40° C. for 20 hours and then blocking UVA for 4 hours three times.
