Moving bed reactor for hydrocarbon pyrolysis

A moving bed reactor comprising:

• a housing;
• a core section disposed within the housing;
• a first heat transfer media disposed within the core section;
• an annular section disposed within the housing;
• a second heat transfer media disposed within the annular section;
• a reactor wall, wherein the reactor wall is disposed within the housing, wherein the reactor wall is disposed between and defines the core section and the annular section;
• a lower gas manifold, wherein the lower gas manifold provides fluid communication from the annular section to the core section through the reactor wall in a lower portion of the core section;
• and
• an upper gas manifold, wherein the upper gas manifold provides fluid communication from the core section to the annular section through the reactor wall in an upper portion of the core section,
• wherein the lower gas manifold and the upper gas manifold are configured to provide a reactant gas pathway from the annular section into the core section through the lower gas manifold, through a reaction zone in the core section, and from the upper portion of the core section to the annular section through the upper gas manifold.
