Heat and hydrogen generation device with ECU controlling air feed device
A burner combustion chamber (3), a reformer catalyst (4) to which burner combustion gas is fed, and a heat exchange part (13a) for heating the air fed to the burner (7) are provided. When the temperature of the reformer catalyst (4) exceeds the allowable catalyst temperature (TX) or when it is predicted the temperature of the reformer catalyst (4) will exceed the allowable catalyst temperature (TX), the air circulation route for guiding air to the burner (7) is switched from a high temperature air circulation route (13) for guiding air heated by the heat exchange part (13a) to the burner (7) to a low temperature air circulation route (14) for guiding air not flowing within the heat exchange part (13a) and lower in temperature than the air heated at the heat exchange part (13a) to the burner (7).

SYSTEMS AND METHODS TO PRODUCE HYDROGEN GAS FROM HYDROGEN SULFIDE
The disclosure relates to systems and methods to produce hydrogen (H.sub.2) gas from hydrogen sulfide (H.sub.2S). H.sub.2S is contacted with a catalyst to form H.sub.2 gas and sulfur adsorbed to the catalyst. The adsorbed sulfur is contacted with oxygen (O.sub.2) gas to convert the adsorbed sulfur to sulfur dioxide (SO.sub.2) and regenerate the catalyst
Fuel-reforming device and fuel-reforming method
Provided is a fuel-reforming device comprising: an ammonia tank (4); a reformer (5) for reforming ammonia and generating high-concentration hydrogen gas having a hydrogen content of at least 99%; a mixing tank (7) for mixing ammonia and hydrogen for temporary storage; and a control means (10) for controlling the respective supply amounts of ammonia and high-concentration hydrogen gas that are supplied to the mixing tank (7). The control means (10) calculates the combustion rate coefficient C of mixed gas with respect to a reference fuel on the basis of equation (1). Equation (1): S.sub.0=S.sub.H?C+S.sub.A?(1?C). In equation (1), S.sub.0 is the combustion rate of the reference fuel, S.sub.H is the combustion rate of hydrogen, S.sub.A is the combustion rate of ammonia, and C is the combustion rate coefficient of mixed gas. In addition, on the basis of equation (2), the control means (10) determines the volume fractions of ammonia and hydrogen that are supplied to the mixing tank. Equation (2): C=1?exp(?A?M.sub.B). In equation (2), M is the volume fraction of hydrogen in mixed gas, and A and B are constants.
PROCESS FOR PRODUCING LOW CARBON HYDROGEN
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.
Process and System for Water-Gas Shift Conversion of Synthesis Gas with High CO Concentration
A method for enriching a synthesis gas in hydrogen is presented. The method includes adding H.sub.2O to the synthesis gas to form a synthesis gas stream that includes hydrogen, carbon monoxide, and steam. The synthesis gas stream has a steam to dry gas molar ratio, S/DG; and an oxygen to carbon molar ratio, O/C. The method includes introducing the synthesis gas stream into a water-gas shift reactor and reacting the synthesis gas stream in the water-gas shift reactor in the presence of a non-iron-based catalyst to produce a shifted synthesis gas. The method further includes controlling an outlet temperature of the synthesis gas stream to remain at or below a critical temperature or to drop to or below the critical temperature by adjusting the S/DG ratio to maintain the O/C ratio below a lower O/C limit or above an upper O/C limit.

In addition, a fuel reformation system for controlling a fuel reformation reaction is provided, which includes a fuel reformation reactor and a control unit.
ENHANCED GASIFICATION SYSTEM AND METHOD
Method and apparatus for converting waste solid sustainable carbon material to chemical products is described herein. The methods add hydrocarbon derived from fossil sources to gas derived from gasifying waste solid sustainable carbon material to enhance hydrogen availability, and in some cases carbon availability, for production of the chemical products. Biomass is used to provide energy to dry solid sustainable carbon material to form dry sustainable carbon material to gasify. Carbon dioxide made by the process is at least partially sequestered to yield a chemical manufacturing process with environmental burden substantially less than conventional processes. Use of the hydrocarbon boosts yield of final products.
