REVERSE FLOW REACTOR WITH RECUPERATIVE REVERSE-FLOW FEED CYCLE

A reverse flow reactor (RFR) and process having a forward reaction feed cycle, a reverse reaction feed cycle, and a reverse regeneration cycle. The heat convected in the forward feed cycle matches the heat convected in the reverse flow cycles. Compared to an RFR without the reverse feed cycle, the three-cycle RPR substantially reduces the regeneration air flow rate, associated compression requirements, and the overall reactor volume, that are required.

PROCESS FOR CONVERTING ALKANES TO OLEFINS
20210261480 · 2021-08-26 · ·

A process and apparatus for converting an alkane to an olefin. In one embodiment, the process involves oxidative coupling of an alkane, e.g., methane, with an oxidant, such as air, to produce an olefin having twice the number of carbon atoms as the alkane, e.g., ethylene. In another embodiment, the process involves oxidative dehydrogenation of an alkane, e.g., ethane, with an oxidant to form an olefin having the same number of carbon atoms as the alkane, e.g., ethylene. The process involves passing a flow of the oxidant from a first flow passage through a porous medium; diffusing a flow of the alkane from a second flow passage into the porous medium; and contacting the reactant alkane and the oxidant in the presence of a catalyst within the porous medium to produce the olefin.

HIGH TEMPERATURE FLOW SPLITTING COMPONENT AND HEAT EXCHANGER AND REFORMING MEANS USING THE SAME

A high-temperature flow-splitting component, applicable to a temperature range from a first temperature to a second temperature, includes an entrance channel, at least one primary channel and at least one subordinate channel. The entrance channel is used for introducing a fluid at a total flow rate. The at least one primary channel for introducing the fluid from the entrance channel at a first flow rate is connected with the entrance channel by a first angle ranging from 90°˜270°. The at least one subordinate channel for introducing the fluid from the entrance channel at a second flow rate is connected with the at least one primary channel by a second angle ranging from 30°˜150°. A sum of the first flow rate and the second flow rate is equal to the total flow rate.

Catalytically heated fuel processor with replaceable structured supports bearing catalyst for fuel cell

A highly compact heat integrated fuel processor, which can be used for the production of hydrogen from a fuel source, suitable to feed a fuel cell, is described. The fuel processor assembly comprises a catalytic reforming zone (29) and a catalytic combustion zone (28), separated by a wall (27). Catalyst able to induce the reforming reactions is placed in the reforming zone and catalyst able to induce the combustion reaction is placed in the combustion zone, both in the form of coating on a suitable structured substrate, in the form of a metal monolith. FeCrAIY steel foils, in corrugated form so as to enhance the available area for reaction, can be used as suitable substrates. The reforming and the combustion zones can be either in rectangular shape, forming a stack with alternating combustion/reforming zones or in cylindrical shape forming annular sections with alternating combustion/reforming zones, in close contact to each other. The close placement of the combustion and reforming catalyst facilitate efficient heat transfer through the wall which separates the reforming and combustion chambers.

10744475 · 2020-08-18 ·

A system and method of continuous production of methanol is disclosed utilizing enriched syngas and a homogenous liquid catalyst comprising an organo-nickel compound, an ether solvent, and an organic methoxide salt. The syngas is directed into a reaction chamber in such a way as to maximize the gas-liquid interface (e.g., an eductor nozzle or bubble column) while two condensers receive tail gas and reactant fluid from the reaction chamber, the latter after undergoing flash separation. Liquid catalyst is recovered and recycled back into the system via the second condenser.

FRACTAL FLUID PASSAGES APPARATUS

Aspects of the present disclosure include branching fluid passages in an apparatus that reduce turbulent flow and generate evenly distributed fluid pressure as the fluids branch off into the different passages. In some embodiments, the branching passages may be subdivided into two sets: the branching passages for the liquid fuel and the branching passages for the liquid oxidizer. In some embodiments, the two sets of passages are carefully designed in an elegant yet extremely intricate manner that is optimized for proper fluid flow and maximal burn efficiency. The ends of all of the passages meet at the injector interface, which dispense the liquids into the combustion chamber for ignition. Generally, these designs are achieved through additive manufacturing, and would be extremely difficult, if not impossible, to be manufactured using traditional techniques.
