Abstract: Disclosed herein are methods of producing a gas at a controlled rate, the methods comprising directing air through a layered bed to produce a gas. The layered bed comprises alternating layers of a layer of dry particles comprising a precursor and a layer of dry particles comprising a proton-generating species. The gas is produced at a rate that is controlled by controlling the presence or absence of air flowing though the layered bed, the amount of time the air flows through the layered bed, the total number of layers in the layered bed, the average thickness of each of the layers of dry particles comprising the precursor in the layered bed, the average thickness of each of the layers of dry particles comprising the proton-generating species in the layered bed, the temperature the method is performed at, or a combination thereof.

Abstract: A system for continuously treating recycled polymeric material includes a hopper configured to feed the recycled polymeric material into the system. An extruder can turn the recycled polymeric material in a molten material. In some embodiments, the extruder uses thermal fluids, electric heaters, and/or a separate heater. The molten material is depolymerized in a reactor. In some embodiments, a catalyst is used to aid in depolymerizing the material. In certain embodiments, the catalyst is contained in a permeable container. The depolymerized molten material can then be cooled via a heat exchanger. In some embodiments, multiple reactors are used. In certain embodiments, these reactors are connected in series. In some embodiments, the reactor(s) contain removable static mixer(s) and/or removable annular inserts.

Abstract: A method and a device system for producing dimethyl oxalate through high-pressure carbonylation of industrial synthesis gases and producing ethylene glycol through dimethyl oxalate hydrogenation. The method comprises the following steps: adopting industrial NO, O2 and methanol as raw materials to perform an esterification reaction to produce methyl nitrite, then adopting industrial CO and methyl nitrite to perform a carbonylation reaction in a plate reactor to produce carbonylation products which mainly include dimethyl oxalate and dimethyl carbonate, separating the carbonylation products to obtain dimethyl carbonate products, and subsequently performing hydrogenation to dimethyl oxalate in the plate reactor to produce ethylene glycol products; and performing coupling recovery treatment to waste acid in the esterification reaction and purge gas in the carbonylation reaction for recycling. The system comprises an esterification reaction system, a carbonylation reaction system, a purge gases and waste acid coupling recovery system and a hydrogenation reaction system.

Abstract: The invention relates to a device and method for distributing a liquid and gas in a multiple-bed downflow reactor, such as a hydrocarbon processing reactor, like a hydrocracker. The device comprises respectively the method uses a distributor device comprising a substantially horizontal collecting tray provided with a central gas passage. Gas passing in downward direction through the central gas passage is forced into a swirling motion by a swirler. This swirling motion has a swirl direction around a vertical swirl axis so that the gas leaves the central gas passage as a swirl. At a location above the collecting tray, a quench fluid is ejected into gas in an ejection direction, which is, viewed in a horizontal plane, at least partly opposite to the swirl direction.

Abstract: A system for reducing dioxygen (O2) present in vapors from oil storage tanks. The system may include an inlet that receives vapors from the tanks; a heating device coupled with the inlet that heats vapors to a first temperature to form heated vapor; and a vessel coupled receiving heated vapor and containing at least one catalyst to reduce dioxygen from the heated vapor. The catalyst may include palladium, and the vessel may include zinc oxide to remove sulfur from the heated vapor. A compressor may be used to compress the vapors. A controller may be provided to monitor O2 concentration in heated vapor, and the controller directs flow of heated vapor to a gas pipeline if the O2 concentration is below a predetermined level; or if the O2 concentration is unacceptably high, the controller directs flow of vapor to be re-circulated within the system to further reduce O2 concentration therein.
