Liquid distributors for monolith catalysts and substrates

The present invention relates to different liquid distributors for monolith in multiphase applications. The present invention more particularly relates to distributor devices in the form of a single injection and multiple injection pipe distributors; shower head distributor comprising a plurality of holes for plunging liquid; a packing of spherical particles with a pre-distributor to split the liquid into manifold streams, before entry into the monolith bed. The present invention provides liquid distributors for monolith in multiphase applications providing improved liquid distribution into the monolith bed resulting in uniform fluid flow in each channel so as to make maximum use of the catalyst surface area.

System and method of dehydrogenative coupling

Embodiments include a system that may include a reactor including a reaction zone and a gas release zone separated by a selectively permeable membrane, wherein the selectively permeable membrane permits hydrogen to pass through the membrane and substantially blocks a substrate and its dehydrogenative coupling product from passing through the membrane. Embodiments further include a method of producing a dehydrogenative coupling product, wherein the method may include exposing a substrate to a catalyst in a reaction zone of a reactor; coupling the substrate to form the dehydrogenative coupling product and hydrogen; and separating the hydrogen from the dehydrogenative coupling product using a selectively permeable membrane and passing the hydrogen to a gas release zone of the reactor.

DEHYDROGENATION CHEMICAL REACTOR

A dehydrogenation chemical reactor includes: a housing; a catalyst part made of a thermally conductive material and disposed in the housing, where the catalyst part has a panel shape, and a catalyst is coated on a surface of the catalyst part to separate hydrogen from an organic hydrogen carrier; a heat transfer pipe which is installed to contact the catalyst part, and conducts latent heat to the catalyst part while pressurized and saturated fluid is supplied therein; and an organic hydrogen carrier line which is connected to the housing to form a passage in which the organic hydrogen carrier is introduced into the housing, contacts the catalyst part to separate hydrogen, and then is discharged.

Methods and systems for producing para-xylene from C8-containing compositions

A method for producing para-xylene (PX) includes introducing a C.sub.8 aromatic-containing composition to a xylene rerun column to separate the C.sub.8 aromatic-containing composition into a xylene-containing effluent and a heavy effluent and passing the xylene-containing effluent to a PX processing loop that includes a PX recovery unit operable to separate a PX product from the xylene-containing effluent, a membrane isomerization unit operable to convert a portion of the MX, OX, or both from the xylene-containing effluent to PX, an EB dealkylation unit operable to dealkylate EB from the xylene-containing effluent to produce benzene, toluene, and other C.sub.7− compounds, and a membrane separation unit operable to produce a permeate that is PX-rich and a retentate that is PX-lean. The permeate is passed to the PX recovery unit for recovery of PX, which the retentate is bypassed around the PX recovery unit circulated through the xylene processing loop.

BATCH SYSTEMS AND METHODS FOR HYDROGEN GAS EXTRACTION FROM A LIQUID HYDROGEN CARRIER

A system for extracting hydrogen gas from a liquid hydrogen carrier may include a hydrogen gas reactor, a catalyst for facilitating extraction of the hydrogen gas from the liquid hydrogen carrier, and a reservoir for containing the liquid hydrogen carrier and a spend liquid hydrogen carrier. The system may be configured to regulate a flow of liquid hydrogen carrier in and out of the hydrogen gas reactor, to move a catalyst relative to a volume of the liquid hydrogen carrier, and to provide a continuous flow of the hydrogen gas, in response to a demand for the hydrogen gas.

SUSTAINABLE SILICATES AND METHODS FOR THEIR EXTRACTION

Liquid silicate products derived from processed organic plant matter (112), such as rice hulls, have improved purity and properties for use in the production of higher purity amorphous silica compositions (180). The liquid silicate can be optically clear, can have a controlled ratio of silica to metal earth oxide components, and can have lower concentrations of undesirable contaminants such as aluminum, chloride, iron, sulfate, and titanium.
