SOLID/HEAT-TRANSPORT GAS REACTOR INCLUDING GAS DIFFUSERS WITH REDUCED RISK OF CLOGGING

摘要

The invention relates to a solid/heat-transport gas reactor including stacked modules (1), characterized in that each module includes diffusers (20), each of which have an upper portion for supporting the solid reactant and a gas-diffusion portion under the upper supporting portion, said solid/heat-transport gas reactor also including a side gas-distributing channel (12) and a side gas-collecting channel (14). Each module includes a double wall (2) within which the gas flows before entering into said diffusers. Two directly consecutive modules in the stack define a holding cavity for receiving a solid reactant at least partially supported by said diffusers arranged in said cavity, wherein the side gas-distributing channels (12) of the stacked modules together form a vertical distributor (112) feeding gas into each of the spaces defined between the double walls (2), and characterized in that the side gas-collecting channels (14) of the stacked modules together form a vertical collector (114) for collecting the gas from each of the holding cavities.
