A process for on-site hydrogen reforming is disclosed. The process includes providing a combined reformer heat exchanger component in which heated air, steam, and hydrocarbon fuel react to form process gas containing hydrogen, and the process gas is cooled via the heat exchanger. The combined components enable reductions in size, materials, costs, and heat loss. Additionally, as the heat exchanger side of the component operates at a cooler temperature, an uninsulated flange for access to the catalyst chamber can be used. A combined combustion heat exchanger component is also provided with similar advantages. Process gas is processed, and hydrogen gas is produced via a purification process.

Low carbon hydrogen will play a crucial role in decarbonization of chemical complexes and manufacturing facilities. Depending on the application, different grades of low carbon hydrogen might be requiredfuel grade (90-99% H2 purity) or chemical grade (>99% H2 purity). The current invention describes a hydrogen production process based on autothermal reforming and CO2 capture to produce low carbon hydrogen with hydrogen rich offgas as part of the feedstock.

An internal combustion engine assembly comprising a fuel reformer, a combustion chamber and a controller. The fuel reformer comprises a first channel and a second channel, a portion of the second channel being adjacent to a portion of the first channel to facilitate heat exchange between the first and second channels. The first channel comprises a catalyst selected to reform ammonia to hydrogen and nitrogen. The first channel is configured to receive ammonia, pass the ammonia over the catalyst and output a first mixture comprising ammonia, hydrogen and nitrogen. The composition of the first mixture depends on a first reformer temperature of the first channel. The combustion chamber is configured to receive the first mixture from the fuel reformer; to receive an oxidant; to combust the first mixture in the oxidant to produce heat and a first product; and to output the first product. The second channel of the fuel reformer is configured to receive the first product.

Processes are disclosed for the conversion of biomass to oxygenated organic compound using a simplified syngas cleanup operation that is cost effective and protects the fermentation operation. The processes of this invention treat the crude syngas from the gasifier by non-catalytic partial oxidation. The partial oxidation reduces the hydrocarbon content of the syngas such as methane, ethylene and acetylene to provide advantageous gas feeds for anaerobic fermentations to produce oxygenated organic compounds such as ethanol, propanol and butanol. Additionally, the partial oxidation facilitates any additional cleanup of the syngas as may be required for the anaerobic fermentation. Producer gases and partial oxidation processes are also disclosed.
