The invention relates to a commercially viable modular ceramic oxygen transport membrane system for utilizing heat generated in reactively-driven oxygen transport membrane tubes to generate steam, heat process fluid and/or provide energy to carry out endothermic chemical reactions. The system provides for improved thermal coupling of oxygen transport membrane tubes to steam generation tubes or process heater tubes or reactor tubes for efficient and effective radiant heat transfer.

Disclosed herein is a method and a reactor for the conversion of a hydrocarbon gas to syngas. The method and reactor utilizes a oxy-hydrogen flame to partially oxidize hydrocarbon gas to syngas by provide an excess flow of oxygen gas. The oxy-hydrogen flame is generated by a multi-tubular oxy-hydrogen burner.

A catalyzing reactor comprising a reactor entrance and a reactor exit and an internal structure arranged for flowing a reacting medium through the reactor from the reactor entrance to the reactor exit. The reactor structure comprising at least one thin walled reactor channel arranged between the entrance and the exit of the reactor. The channel having a channel wall that includes a catalyst and that defines a flow path, in which channel in use, a catalyzed exothermic reaction takes place in the medium as it flows along the flow path. The at least one channel is looped to have a portion of its flow path that is downstream with respect to the reactor entrance in heat exchanging contact with a portion of a flow path that is that is more upstream with respect to the reactor entrance, so as to transfer heat between a downstream portion of the reacting medium to an upstream portion thereof.

The present invention provides a method for manufacturing a polymer by a flow-type reaction. The method includes introducing a liquid A of an anionic polymerizable monomer, a liquid B of an anionic polymerization initiator, and a polymerization terminator into different flow paths, allowing the liquids to flow in the flow paths, allowing the liquid A and the liquid B to join together, subjecting the monomer to anionic polymerization while the liquids having joined together are flowing to downstream in a reaction flow path, and allowing a solution, which is obtained by the polymerization reaction and flows in the reaction flow path, and the polymerization terminator to join together so as to terminate the polymerization reaction and to obtain a polymer having a number-average molecular weight of 5,000 to 200,000. A static mixer is disposed in the reaction flow path, and a polymer having a number-average molecular weight equal to or greater than 2,000 is introduced into an inlet port of the mixer. The present invention also provides a flow-type reaction system suitable for performing the manufacturing method.

The present invention is related to a two-step carboxylation reaction of an aryl group using continuous flow reaction conditions. This process permits large scale synthesis of useful reaction products in high yield.

A system and method including providing a feed having alkyl-bridged multi-aromatic compounds to a tubular reactor, heating the tubular reactor, and cleaving an alkyl bridge of the alkyl-bridged multi-aromatic compounds.

A thermochemical labyrinth reactor is disclosed. The reactor has a reoxidation zone and a reduction zone with electric heaters. A recuperation zone connects the reduction and reoxidation zones with first and second channels, the first channel adjoining the second channel, being separated by windows allowing an exchange of thermal radiation between channels while preventing gas exchange. The reactor also includes reactor plates composed of a reactive material, and a transit system running through the three zones, with the transit system configured to shuttle the plates between the reduction zone and the reoxidation zone, moving the plates along a circuit. The reactor also has a feedstock gas emitter to introduce a feedstock gas flowing opposite the movement of the plates. A gas extractor is configured to extract a product gas resulting from the feedstock gas being split by the oxidizing reactive material. All three zones are surrounded by an insulating housing.

The invention is directed to a chemical reactor (100) having (a) two or more gas reactor elements (12) with each gas reactor element (12) having (i) a first reaction chamber (38), and (ii) a feed assembly unit (36), (b) a second reaction chamber (20) coupled with each of the two or more gas reactor elements (12) and configured to independently receive two or more product streams from the two or more gas reactor elements (12); and optionally, (c) a gas converging section (40) located downstream to the second reaction chamber (20). The invention is further directed to a method of producing chemical products using the chemical reactor (100) of the present invention.
