Abstract:
Methodologies, systems, and devices are disclosed for generating a chemical compound. A reaction chamber holds an amount of a precursor chemical, an activator chamber holds an amount of an activator chemical, and a quenching and neutralizer chamber holds an amount of quenching and neutralizing chemicals. A pump transfers the activator chemical from the activator chamber to the reaction chamber, where the activator chemical reacts with the precursor chemical to form the desired chemical compound. The desired chemical compound is allowed to exit the reaction chamber. Subsequently, the pump transfers the quenching and neutralizing chemicals from the quenching and neutralizer chamber to the reaction chamber, resulting in a quenched and neutralized solution.

Abstract:
A device includes a case having a surface with a perforation and a cavity. A membrane is supported by the case inside the cavity and has an impermeable valve plate positioned proximate the perforation. The membrane is water vapor permeable and gas impermeable and flexes responsive to a difference in pressure between the cavity and outside the cavity to selectively allow water vapor to pass through the perforation into the cavity as a function of the difference in pressure.
Abstract:
In the thermochemical water splitting process by the Cu—Cl cycle, oxygen gas is produced by a thermolysis process in a three-phase reactor. A precise knowledge of the hydrodynamic and heat transfer analyses is required for the scale-up of the thermolysis reactor. However, in the experimental studies of the scale up analysis, there are some challenges in using the actual materials of the thermolysis reactor products (i.e. molten salt CuCl and oxygen gas). In accordance with the teachings herein, alternative materials are defined, by using dimensional analyses, to simulate the hydrodynamic and heat transfer behaviors of the actual materials. It has been found that these alternative materials are liquid water at 22±2° C. and helium gas at 90±2° C. The alternative materials provide safe environment for the experimental runs as well as lower operating temperature. Furthermore, these alternative materials are more readily available and are low cost.
Abstract:
Methods and systems for producing hydrogen from methane or other fuels that has lower input heat requirements than conventional steam reformation schemes are provided. The system has a reactor with a controlled feed of fuel, water/steam, CO and recycle gases. The methods generally use significantly high amounts of steam (water) and carbon monoxide (CO) in the feed that substantially enhances the reaction rate of the water-gas shift reaction, which transforms CO and H2O to CO2 and H2. Since this reaction is exothermic, its enhancement alters the endothermic nature of the overall reforming process to the point where the overall reforming process is no longer endothermic. The CO requirements may be met in part with the reverse water-gas shift reaction from CO2 produced by the reactor. The lower heat requirements may be satisfied with renewable sources such as solar or from hydrogen produced by the system.

The distribution areas are characterized by:the discontinuity of the walls along the distribution area on the side of the inflow of gaseous flows or on the side of the outflow thereof; andthe increase in the width of the walls along the distribution area on the side of the inflow of gaseous flows or on the side of the outflow thereof.
Abstract:
Systems and methods for reducing or eliminating corrosion of components of a reactor system, including a supercritical water gasification system, are described. The reactor system may include various system components, such as one or more pre-heaters, heat exchangers and reactor vessels. The system components may be configured to receive a reactor fluid corrosive to an inner surface thereof and to separately receive a protective fluid that has a higher density and is substantially immiscible with the reactor fluid. A rotating element may be configured to generate a rotational force that forces at least a portion of the protective fluid to flow in a layer between the reactor fluid and at least a portion of the inner surface, the layer operating to reduce corrosion by forming a barrier between the reactor fluid and at least a portion of the inner surface.
