Title:
PRODUCTION METHOD OF CATALYST SUPPORT AND PRODUCTION METHOD OF FIBROUS CARBON NANOSTRUCTURE
Document Type and Number:
WIPO Patent Application WO/2021/060419
Kind Code:
A1
Abstract:
The present invention relates to a method for producing a catalyst support used to produce a fibrous carbon nanostructure. This production method comprises: a stirring step for stirring a particulate support by rotating a substantially cylindrical rotary drum about the center axis thereof; a spraying step for spraying a catalyst solution onto the particulate support in the rotary drum; and a drying step for drying the catalyst solution attached to the particulate support by introducing a dry gas from the outside of the rotary drum into the rotary drum. In addition, in this production method, at least a portion of a time period in which the stirring step is performed overlaps with at least a portion of a time period in which the spraying step is performed.
