摘要： The present invention relates to a method of reducing carbon dioxide and air pollutants, and more particularly to a method of simultaneously reducing emissions of carbon dioxide and air pollutants, in which an off-gas containing carbon dioxide, SOx, and NOx is passed through a sulfur-oxidizing microorganism reactor, thereby converting carbon dioxide present in the off-gas into biomass, SOx into sulfate ions, and NOx into amino-N.

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： The present disclosure provides a method of treating waste plastic pyrolysis oil. The method includes a first step of washing waste plastic pyrolysis oil with water and then removing moisture; a second step of mixing the waste plastic pyrolysis oil from which the moisture is removed and a sulfur source to prepare a mixed oil; a third step of hydrotreating the mixed oil with hydrogen gas in the presence of a hydrotreating catalyst; a fourth step of separating the hydrotreated mixed oil into a liquid stream and a gas stream to obtain liquid pyrolysis oil; and a fifth step of recovering hydrogen gas from the separated gas stream and recycling the recovered hydrogen gas to the third step.

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.
