Provided is a method for manufacturing syngas including (S1) heat-treating organic wastes under hydrogen and a catalyst in a first reactor; (S2) separating the catalyst and the hydrogen from a product of (S1) and recovering a first mixed gas from which the catalyst and the hydrogen have been removed; (S3) reforming the first mixed gas recovered in (S2) with water vapor to form a product; (S4) separating carbon dioxide from a product of (S3) and recovering a second mixed gas from which the carbon dioxide has been removed; (S5) converting the carbon dioxide separated in (S4) into carbon monoxide through a reverse Boudouard reaction in the second reactor; and (S6) mixing the hydrogen separated in (S2), the mixed gas recovered in (S4), and the carbon monoxide converted in (S5) to produce syngas.

The present disclosure relates to a method of operating a reformer, wherein the reformer is operated at least with a first hydrocarbon mixture and a second hydrocarbon mixture. The reformer has a primary reformer that is supplied with a first gas stream. The reformer also has a secondary reformer that is supplied with a semifinished product gas stream from the primary reformer and with an air stream. The first gas stream and the air stream are used to form the quotient of the first gas stream divided by the air stream. A threshold value is defined, wherein the reformer is shut down below the threshold value. The threshold value is compared with the product of the quotient of the first gas stream divided by the air stream multiplied by a factor H, wherein the factor is defined depending on the chemical composition of the gas stream.

A method of maintaining a syngas composition ratio during an upset condition, including detecting a reduction in the import carbon dioxide flow rate with a carbon dioxide import stream flow sensor, evaluating the reduction in carbon dioxide flow rate or carbon dioxide pressure in a controller, performing one or more predetermined corrective actions as instructed by the controller. Wherein the predetermined corrective actions are chosen from the following: opening a CO2 import stream flow valve, opening a hydrocarbon and steam stream feed valve, opening a CO2 backup stream control valve, opening a syngas backup letdown valve, and starting a composition adjustment unit.

The present invention relates to net-zero hydrogen plants and methods of operating said plants having a lower cost and much larger scale compared to electrolysis driven plants utilized to produce green hydrogen.

There is described a method of producing hydrogen and nitrogen using a feedstock gas reactor. Reaction of feedstock and combustion gases in the reactor produces hydrogen and nitrogen through pyrolysis of the feedstock gas. Parameters of the process may be adjusted to control the ratio of hydrogen to nitrogen that is produced such that it may be suitable, for example, for the synthesis of ammonia.
