Abstract
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 the vessel and wherein the product is discharged from the vessel by falling from the bed.
Claims18
A method for producing a particulate carbon product comprising:
- flowing a gas through an inlet port in a lower section of a reactor vessel having a first cross-sectional area;
- passing said gas from the lower section to an upper section of the reactor vessel having a second cross-sectional area, via a middle section having a cross-sectional area smaller than said first and second cross-sectional areas;
- flowing said gas through a gas outlet port in the upper section;
- using the flow of said gas to support a reaction bed of catalyst-containing particulate material in said upper section;
- harvesting a carbon product by allowing it to fall from said upper section into said lower section;
- and
- discharging particulate carbon product from the lower section of the reactor vessel via an outlet port.
