Method and system for thermal energy recovery from the production of solid carbon material by reducing carbon oxides

摘要

A method for recovering thermal energy from the production of at least one solid carbon material is to produce at least one solid carbon material and a gaseous effluent stream containing water vapor at a temperature of about 400 ° C. or higher, about 1 to 105 Pascals. Reacting at least one carbon oxide material and at least one gaseous reducing material in the presence of the above pressure and at least one catalyst material. Thermal energy is extracted from a gaseous effluent stream containing water vapor. Other methods of generating recoverable thermal energy are disclosed, such as solid carbon production systems with thermal energy recovery.
