Abstract
A method of producing hydrogen may include: providing a catalyst-carbon gel; and flowing a hydrocarbon through a catalyst, wherein catalyst is a metal or mixture of metals that is non-wetting to solid carbon at 1 bar absolute and 10° C. above a melting point of the metal or mixture of metals.
Claims20
A method comprising:
- providing a catalyst-carbon gel;
- and
- flowing a hydrocarbon through the catalyst-carbon gel under conditions sufficient to pyrolyze the hydrocarbon, wherein a catalyst of the catalyst-carbon gel is a metal or mixture of metals that is non-wetting to solid carbon at 1 bar absolute and 10° C. above a melting point of the metal or mixture of metals.
A method comprising:
- flowing a hydrocarbon through a catalyst that is a metal or mixture of metals that is non-wetting to solid carbon at 1 bar absolute and 10° C. above a melting point of the metal or mixture of metals;
- entraining gaseous and/or liquid catalyst with the hydrocarbon;
- condensing and/or depositing the gaseous and/or liquid catalyst downstream of the catalyst;
- and
- pyrolyzing at least a portion of the hydrocarbon;
- thereby forming a catalyst-carbon gel.
3 more elements
A catalyst-carbon gel comprising:
- a plurality of catalyst particles at least partially coated with a solid carbon coating, wherein a catalyst of the plurality of catalyst particles is a metal or mixture of metals that is non-wetting to solid carbon at 1 bar absolute and 10° C. above a melting point of the metal or mixture of metals;
- and
- solid carbon not contacting portions of the plurality of catalyst particles and not being part of the solid carbon coating.
