US 2026/0250587 A1 · METHOD FOR OBTAINING A SYNTHESIS GAS FROM WASTE PRODUCTS VIA A GASIFICATION REACTION IN CONJUNCTION WITH A REFORMING REACTION WITH THERMAL ENERGY RECIRCULATION

Abstract

Disclosed are methods and devices for obtaining a synthesis gas from a waste product via a gasification reaction in conjunction with a reforming reaction under thermal energy recirculation. A feed material and a first and/or second oxidizing agent are fed into a gasification reactor. The feed material includes a solid, liquid and/or gaseous waste product. The feed material is gasified by the first and/or second oxidizing agent, with the addition of thermal energy, into a hydrocarbon gas mixture and at least one by-product including bottom ash and/or fly ash. The hydrocarbon gas mixture is fed into a reformer unit and processed into a raw synthesis gas with the first and/or second oxidizing agent. At least part of the thermal energy released by processing the raw synthesis gas is recirculated into the gasification reactor to provide at least part of the thermal energy for gasification of the feed material.

Dependent claims

A method for obtaining a synthesis gas from at least one waste product via a gasification reaction in conjunction with a reforming reaction under thermal energy recirculation, wherein the method comprises the following steps:

S1:
Feeding a feed material and a first and/or second oxidizing agent into a gasification reactor, wherein the feed material comprises, in particular, at least one solid, liquid, and/or gaseous waste product;
S2:
Gasifying the feed material in the gasification reactor in the presence of the first and/or second oxidizing agent with the addition of thermal energy into a hydrocarbon gas mixture, wherein at least one by-product is produced, wherein the by-product comprises, in particular, bottom ash and/or fly ash;
S3:
Feeding the hydrocarbon gas mixture from the gasification reactor into a reformer unit;
S4:
Processing the hydrocarbon gas mixture in the reformer unit into a raw synthesis gas with the addition of the first and/or second oxidizing agent;
wherein at least a portion of thermal energy generated in step S4 is recirculated to the gasification reactor to provide at least a portion of the thermal energy supplied in step S2.
