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.
摘要:
A method for producing 1,1,1,2-tetrafluoropropene and/or 1,1,1,2,3-pentafluoropropene using a single set of four unit operations, the unit operations being (1) hydrogenation of a starting material comprising hexafluoropropene and optionally recycled 1,1,1,2,3-pentafluoropropene; (2) separation of the desired intermediate hydrofluoroalkane, such as 1,1,1,2,3,3-hexafluoropropane and/or 1,1,1,2,3-pentafluoropropane; (3) dehydrofluorination of the intermediate hydrofluoroalkane to produce the desired 1,1,1,2-tetrafluoropropene and/or 1,1,1,2,3-pentafluoropropene, followed by another separation to isolate the desired product and, optionally, recycle of the 1,1,1,2,3-pentafluoropropene.
摘要:
The invention relates to the production of synthesis gas by means of particularly a series arrangement of heat exchange reforming and autothermal reforming stages, in which the heat required for the reforming reactions in the heat exchange reforming stage, is provided by hot effluent synthesis gas from the autothermal reforming stage. More particularly, the invention relates to optimisation of the operation and control of an arrangement of heat exchange reforming and autothermal reforming stages and introduction of an additional waste heat boiler.
摘要:
Device and method for handling multi-component mixtures, comprising at least two not completely mixable fluid phases. The device comprises an arrangement of at least two high-pressure separators, being operatively connected each with a low-pressure separator. Each high-pressure separator comprises an outlet line for volatile gaseous constituents. Each low-pressure separator is operatively connected to a gas collecting container or shares at least one gas collecting container with a further low-pressure separator. At least one high-pressure separator has at least one outlet connection for gaseous constituents, being connected with a part to the analysis. The device is used in high-throughput research or in combinatory chemistry, preferably for the research of multi-component mixtures produced in experiments with catalyst, or in connection with high-pressure processes.
摘要:
A method and apparatus for simultaneously performing chemical reactions and determining molecular transport dynamics on a plurality of samples such as thin film samples. The apparatus of the present invention is capable of containing multiple samples in individual sample holding positions in a sample holder within a housing and maintaining those holding positions in chemical isolation from each other. Under control of a computerized controller, the apparatus positions the sample holder so that each sample holding position may be positioned adjacent to one or more ports connected to a distribution manifold. The apparatus exposes each sample to one or more fluids in liquid or gas phase, thereby carrying out a chemical reaction and/or determining molecular transport dynamics under controlled temperature and pressure conditions. The sample holding positions may be positioned in an analytical measurement station within the housing so that the resulting chemical compound or mixture may be characterized.
