초록 ▼

Dual pore-structured carbon and graphite consist essentially of a macroporous agglomeration of strongly bonded microporous grains of carbon or graphite the radii of the macropores therein being from substantially 10 to 350 mm2/sec/atmos and a porosity of from 30 to 50%. Such materials are produced by including in a mixture of tar or pitch and finely divided solid carbonaceous material in suitable proportions, a particulate eliminable non-carbon-forming material having a particle size of 10 to 350 m

대표청구항 ▼

An artificial dual pore-structured carbon or graphite which is suitable for use as a catalyst substrate or an electrode material consisting essentially of a macro-porous agglomeration of strongly bonded microporous grains of carbon or graphite, the radius of the macropores being from substantially 10 to 350 m0.2 to 1.0 m0.70 to 1.50 gms/cc., a permeability to gases of from 20 to 500 cm2/sec/atmos, and a porosity of from 30 to 50%. A process for the production of an artificial dual pore-structured carbon suitable for use as a catalyst substrate or an electrode material consisting essentially of a macroporous agglomeration of strongly bonded microporous grains of carbon which process comprises preparing an aggregate of (a) 15-35% by weight of tar or pitch and (b) 85-65% by weight of a finely divided carbonaceous material having a particle size up to 100 microns, intimately admixing the resulting aggregate with a particulate, eliminable, non-carbon forming material which material is substantially insoluble in said aggregate, shaping the resulting product is desired shape by compression or extrusion, heating the resulting shaped product to a carbonisation temperature for a time sufficient to carbonize the pitch content thereof, cooling the carbonized shaped material and, when a residue of said particulate material is present in the cooled carbonaceous product, treating said cooled product to remove said residue therefrom, said particulate eliminable material being used in the form of particles which will produce macropores having a radius of 10 to 350 m0.70 to 1.50, a permeability to gases of from 20 to 500 cm3/sec/atmos and a porosity of 30 to 50%.
