Countercurrent contacting devices and method of manufacture
The contacting device for countercurrent contacting of fluid streams and having a first pair of intersecting grids of spaced-apart and parallel deflector blades and a second pair of intersecting grids of spaced-apart and parallel deflector blades. The deflector blades in each one of the grids are interleaved with the deflector blades in the paired intersecting grid and may have uncut side portions that join them together along a transverse strip where the deflector blades cross each other and cut side portions that extend from the uncut side portions to the ends of the deflector blades. At least some of the deflector blades have directional tabs and associated openings to allow portions of the fluid streams to pass through the deflector blades to facilitate mixing of the fluid streams.

Hydrogen generator
A hydrogen generator includes a reaction vessel, a water supply, a temperature adjustor, and a controller. The reaction vessel houses a hydrogen generating material having hydrogen generating ability. The hydrogen generating material includes a two-dimensional hydrogen boride sheet having a two-dimensional network and containing multiple negatively charged boron atoms. The controller is configured to execute a hydrogen generating mode to generate hydrogen from the hydrogen generating material and a regenerating mode to recover the hydrogen generating ability of the hydrogen generating material. The controller controls the temperature adjustor to heat the hydrogen generating material at a first predetermined temperature during the hydrogen generating mode. The controller controls the temperature adjustor to adjust the temperature of the hydrogen generating material to a second predetermined temperature and controls the water supply to supply water during the regenerating mode.
FILL SHEETS AND RELATED FILL PACK ASSEMBLIES
A fill sheet for cooling heat transfer fluid in a cooling tower includes an air intake end, an air outlet end, a top edge and a bottom edge. The air outlet end is positioned opposite the air intake end along a lateral axis. The top edge connects the air intake end and the air outlet end and the bottom edge also connects the air intake end and the air outlet end. The bottom edge is positioned opposite the top edge along a vertical axis. A plurality of flutes extends generally parallel to the lateral axis between the air intake end and the air outlet end. An offset extends generally parallel to the vertical axis. A first flute of the plurality of flutes transitions from a first peak at a first side of the offset to a first valley at a second side of the offset.

Wettable media and method of making the same
A wettable media pad comprises an inlet side and an outlet side and a porous structure made from a non-woven material, comprising a plurality channels having a hexagonal cross-section defined by six walls, the channels running from the inlet side to the outlet side, wherein the wettable media pad is configured to direct fluid from a top surface of the media pad to a bottom surface of the media pad along at least one of the walls of the channels, wherein the wettable media pad is configured to exchange heat and mass between a fluid positioned on or in a wall of the channels and a gas flowing through the channels as the gas flows from the inlet side to the outlet side, and wherein the wettable media pad is produced with additive manufacturing. A method of making a wettable media pad is also described.
PROCESS FOR PRODUCING SYNTHESIS GAS WITH REDUCED STEAM EXPORT
A process is proposed for producing synthesis gas with reduced steam export by catalytic steam reforming of a hydrocarbonaceous feed gas with steam in a multitude of reformer tubes in a burner-heated reformer furnace to form a steam reforming flue gas. This process includes a configuration of the reformer tubes as reformer tubes with internal heat exchange and the use of a structured catalyst. For amounts of export steam between 0 and 0.8 kg of export steam per m.sub.N.sup.3 of hydrogen produced, these features interact synergistically when particular steam reforming conditions are selected.
Hydroprocessing reactor to lower pressure drop and extend catalyst life
A reactor for accommodating high contaminant feedstocks includes a reactor vessel having an inlet for introducing a feedstock containing contaminants into an interior of the reactor vessel. A basket is located within the reactor vessel interior and contains a particulate material for removing contaminants from the feedstock to form a purified feedstock that is discharged to a purified feedstock outlet. A catalyst is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.
