Document Type and Number:
WIPO Patent Application WO/2023/095737
Kind Code:
A1
Abstract:
[Problem] To provide a graphene oxide manufacturing system and a graphene oxide manufacturing method that can manufacture high-quality graphene oxide while suppressing equipment costs. [Solution] A graphene oxide manufacturing system 10 comprises a centrifugal separation device 16 and a rotating filtration device 18. The centrifugal separation device 16, by performing centrifugal separation processing on a graphite oxide dispersion obtained by oxidizing graphite, performs deoxidation processing to remove acid from the graphite oxide. The rotating filtration device 18 performs filtration processing on the graphite oxide dispersion which has been subjected to the deoxidation processing. The rotating filtration device 18 comprises a layer thickness adjustment blade 184 that is configured to apply force for adjusting the accumulation thickness of a cake layer 186, the cake layer 186 being a layer added to a filtration filter 182 and containing graphite oxide,
