GRANULAR AGGLOMERATE OF CARBONACEOUS FINE FIBROUS BODY

摘要

PROBLEM TO BE SOLVED: To provide granular agglomerate of a carbonaceous fine fibrous body which has high bulk density, excellent handleability and is efficiently and inexpensively mass-produced as the granular agglomerate of the carbonaceous fine fibrous body having homogeneous shape and property without causing solidification and clogging in the production process. SOLUTION: The granular agglomerate of the carbonaceous fine fibrous body has≥200 kg/m3bulk density. The granular agglomerate of the carbonaceous fine fibrous body is produced by introducing a catalyst particle and a carbon source gas into a jet bed reactor 30, producing agglomerate of the carbonaceous fine fibrous body having 10-200μm average particle diameter while forming a jet bed and introducing the agglomerate particle and the carbon source gas into fluidized bed reactors 40 and 50 to grow the agglomerate while forming a fluidized bed of the agglomerate.
