摘要:
Disclosed are a radiating wall catalytic reactor for providing heat from the inside wall surface 8 of a reaction chamber 1 by radiation 16 to support an overall endothermic gas phase chemical reaction taking place in the reaction chamber 1, and a process for carrying out a chemical reaction in the reactor. The reaction chamber 1 is provided with an entrance port 2 for introducing a gaseous reactant(s) in a continuous manner into the chamber 1 and an exit port 3 to enable the gaseous product(s) to leave the chamber 1 in a continuous manner. The reaction chamber 1 includes a plurality of catalyst segments (A)5, which has one void segment (B)6 on either side of it; and the reaction chamber 1 is made of a material(s) that is (are) suitable to resist a temperature of 700° C. or more.

In a reactor tube in which a plurality of catalyst carriers are disposed, each catalyst carrier is an annular container having a perforated inner wall defining a tube, a perforated outer wall, a top surface closing the annular container and a bottom surface closing the annular container. A surface closes the bottom of the tube and a skirt extends upwardly from the perforated outer wall of the annular container from a position at or near the bottom surface of the container. A seal is located at or near the top surface and extends outward from the container beyond an outer edge of the skirt. The reactor tube additionally includes a temperature measuring device configured to measure the temperature in two or more catalyst carriers within the reactor tube.

Disclosed are a gas to liquids (GTL)—floating production, storage and offloading (FPSO) system that can be used in offshore oil-gas fields or stranded gas fields and a method for producing synthetic fuel using the same. More particularly, the disclosure relates to a GTL-FPSO system capable of producing liquid synthetic fuel from gas extracted from stranded gas fields or associated gas extracted from oil-gas fields, including a reforming reactor and a liquid hydrocarbon producer, and a method for producing the same.
摘要:
Systems and methods conducive to the formation of one or more alkene hydrocarbons using a methane source and an oxidant in an oxidative coupling of methane (OCM) reaction are provided. One or more vessels each containing one or more catalyst beds containing one or more catalysts each having similar or differing chemical composition or physical form may be used. The one or more catalyst beds may be operated under a variety of conditions. At least a portion of the catalyst beds may be operated under substantially adiabatic conditions. At least a portion of the catalyst beds may be operated under substantially isothermal conditions.
摘要:
In a fixed-bed flow reaction using a multitubular heat exchange type reactor, an object of the present invention is to provide a novel packing for a reaction tube, which can control the reaction ratio in the vicinity of the reaction tube inlet, reduce the load unevenly placed on the catalyst in the reaction region, and distribute the load on the entire catalyst layer, a heat exchange type reactor, and a reaction method using the reaction tube. The packing for a reaction tube of the present invention is characterized in that the volume is continuously or step-by-step decreased from one end part or midway toward the other end part.
摘要:
The present invention describes a device and a method for dense and homogeneous loading of catalyst into the annular space 4 of bayonet tubes defined by an external tube 6 and an internal tube 5 used in a steam reforming reactor, said device using a rigid auxiliary tube 7 for introducing solid particles into said annular zone 4.
摘要:
The present disclosure relates to a single shell open interstage reactor (“SSOI”). The SSOI comprises a first reaction stage, an interstage heat exchanger, an open interstage region, and a second reaction stage. The SSOI may be configured for upflow or downflow operation. Further, the open interstage region of the SSOI may comprise a supplemental oxidant feed. When the open interstage region comprises a supplemental oxidant feed, the SSOI may further comprise a supplemental oxidant mixing assembly. Processes for producing acrylic acid through the oxidation of propylene are also disclosed.
