METHOD FOR STORING PETROLEUM-BASED HIGH-SOFTENING-POINT PITCH

Document Type and Number:

WIPO Patent Application WO/2024/034930

Kind Code:

A1

Abstract:

A method for storing petroleum-based high-softening-point pitch, of the present invention, comprises the steps of: (a) injecting petroleum-based high-softening-point pitch into a storage tank; and (b) storing the petroleum-based high-softening-point pitch, wherein the softening point of the petroleum-based high-softening-point pitch is 150-300°C, and step (b) comprises (b-1) a process of periodically charging an inert gas into the petroleum-based high-softening-point pitch and/or (b-2) a process of stirring the petroleum-based high-softening-point pitch.
