Abstract: Provided is a method for converting waste plastic pyrolysis oil into light olefins with a high yield. The method includes: (1) inputting waste plastic pyrolysis oil into a reactor; (2) allowing the waste plastic pyrolysis oil to react in the reactor in the presence of a catalytic cracking catalyst containing a first metal and a second metal to form a product; and (3) recovering light olefins by separating the catalytic cracking catalyst and oil from the product obtained in step (2).

Abstract: 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.

Abstract: The present invention relates to a Bacillus subtilis JCK-1398 strain (Accession No. KCTC 14084BP) having induced resistance activity in pine trees and various plants, a pesticidal or antibacterial composition comprising same as an active ingredient, a composition for controlling plant diseases or pests, and a control method using same. The Bacillus subtilis JCK-1398 strain of the present invention was experimentally confirmed to have control activity against pests, nematodes, and fungi, which cause various plant diseases, by inducing resistance in a host. Thus, the Bacillus subtilis JCK-1398 strain of the present invention can be effectively used to control related plant diseases and can be spread over a wide area through foliar spraying, and therefore is expected to be able to prevent the spread of pine wilt disease at low cost.

Abstract: The present invention relates to Bacillus methylotrophicus strain DR-08 which produces a natural volatile compound and has antimicrobial activity, and a use thereof. The Bacillus methylotrophicus strain DR-08 according to the present invention, which is an antagonistic microorganism for controlling phytopathogenic microorganisms, and secondary metabolites produced by the strain, which include antibacterially- and antifungally-active non-volatile and volatile materials, are harmless to humans and domestic animals, and exhibit excellent control activity against various phytopathogenic bacteria and fungi while not causing environmental pollution. Thus, the strain and the secondary metabolites can be very usefully used for controlling various plant diseases in an environmentally-friendly manner.
