A method of controlling cooling in an aircraft system includes endothermically cracking a fuel to increase its cooling capacity using a catalyst that includes at least one transition metal compound of at least one of carbides, nitrides, oxynitrides, oxycarbonitrides, oxycarbides, phosphides, and combinations, and the transition metal includes at least one of zirconium, hafnium, tantalum, niobium, molybdenum, tungsten, platinum, palladium, rhodium, iridium, ruthenium, osmium, rhenium, and combinations thereof. The cracked fuel is used to cool a heat source that includes an aircraft component.

A contaminant removal system is disclosed for selectively removing contaminants from a fluid stream. The contaminant removal system has a catalytic reactor of the type that is susceptible to deactivating agents, and is configured to remove contaminants from a fluid stream. The contaminant removal system has a first adsorbent device positioned upstream, with respect to the fluid stream direction, of the catalytic reactor, that is configured to chemically bind with and remove the deactivating agents from the fluid stream. The contaminant removal system can have a second adsorbent device positioned downstream, with respect to the fluid stream direction, of the catalytic reactor. The second adsorbent device is configured to remove undesirable byproducts that may be generated when the catalytic reactor removes contaminants from the fluid stream.

Systems and methods for removal of contaminants from fluid streams

A catalytic device comprises a mixed structure of photocatalyst and silica. The mixed structure may be comprised of alternating layers of photocatalyst and silica, a layer having a uniform mixture of photocatalyst particles and silica particles, or a layer having a graded mixture of photocatalyst particles and silica particles.

The present disclosure relates to a fluid purification device that has a deactivation resistant photocatalyst having nanocrystallites of less than 14 nanometers (nm) in diameter with at least 200 msurface area/cmof skeletal volume in cylindrical pores of 5 nm in diameter or larger, with the mode of the pore size distribution 10 nm or more.

Deactivation resistant photocatalysts

A method for regenerating at least one impurity-adsorbing sorbent bed includes passing impurity-containing fluid through the impurity-adsorbing bed. The impurity-adsorbing sorbent bed adsorbs an impurity in the impurity-containing fluid to produce a purified fluid. A portion of the purified fluid is sent back through the impurity-adsorbing sorbent bed that contains the adsorbed impurity. The impurity-adsorbing sorbent bed is exposed to microwave energy to desorb the impurity adsorbed on the impurity-adsorbing sorbent bed.

On-board fuel desulfurization unit

A photocatalyst system for volatile organic compounds with two parts that include a photocatalyst layer on a substrate and a porous overlayer. The photocatalyst layer is reactive with volatile organic compounds when UV light is projected on it. The overlayer is situated on the photocatalyst layer. The overlayer is UV transparent and has an interconnected pore network that allows contaminated air to pass through the overlayer. The size and the shape of the interconnected pores acts to selectively exclude certain contaminants that can deactivate the photocatalyst.

Preparation and manufacture of an overlayer for deactivation resistant photocatalysts

Deactivation resistant photocatalysts can be formulated by coating one or more photocatalyst crystals onto a suitable substrate. The photocatalyst crystals are doped with a dopant M. The dopant can be used to repel the silicon-based compound or be used to attract the silicon-based compound. The dopant can uniformly be distributed in the photocatalyst crystals. The dopant can be introduced only to photocatalyst crystals between about 0.1 to about 2 nanometers below the surface of the structure. The doped photocatalyst crystals can be interdispersed with non-doped photocatalyst crystals.
