Abstract:
This invention relates to a method for the production of particulate carbon products in a reactor vessel wherein gas flow between a gas inlet port and a gas outlet port suspends a bed of catalyst-containing particulate material in said vessel and wherein the product is discharged from said vessel by falling from the bed.
Abstract:
This invention provides a reactor (1) for carbon nano- fibre production comprising a generally horizontal elongate cylindrical reaction vessel (902) arranged to rotate about its cylindrical axis and containing in use a particulate catalyst-containing reaction bed (72), said reaction vessel having a gas inlet port (1001) and a gas outlet port (1002) positioned such that one of said inlet and outlet ports is in said bed and the other is outside said bed.
Abstract:
This invention relates to a process for the preparation of fibrous carbon which comprises contacting a metallic catalyst with a carbon-containing gas at elevated temperature, characterized in that said catalyst is a porous metal comprising a transition metal or an alloy thereof.
