Process and Apparatus for Steam-Methane Reforming

Methane reacts with steam generating carbon monoxide and hydrogen in a first catalytic reactor; the resulting gas mixture undergoes Fischer-Tropsch synthesis in a second catalytic reactor. In the steam/methane reforming, the gas mixture passes through a narrow channel having mean and exit temperatures both in the range of 750° C. to 900° C., residence time less than 0.5 second, and the channel containing a catalyst, so that only reactions having comparatively rapid kinetics will occur. Heat is provided by combustion of methane in adjacent channels. The ratio of steam to methane may be about 1.5. Almost all methane will undergo the reforming reaction, almost entirely forming carbon monoxide. After Fischer-Tropsch synthesis, the remaining hydrogen may be fed back to the combustion channels. The steam for the reforming step may be generated from water generated by the chemical reactions, by condensing products from Fischer-Tropsch synthesis and by condensing water vapor generated in combustion.

Continuous process for the production of polymers

Method of preparing a polymer under predetermined temperature conditions, and apparatus therefor

A method of preparing a polymer under predetermined temperature conditions comprises conducting the polymerization within a closed reaction chamber configured such that most or all of an inner surface has heat exchange capability. The chamber's dimensions are such that the polymerization mixture contacts the effective heat exchange surface sufficiently to ensure that the temperature throughout the polymerization mixture does not vary more than a few degrees from a desired temperature. In one embodiment the chamber is formed of two adjacent, parallel heat exchange plates, wherein at least one plate has a peripheral lip which, in contact with the opposing plate, forms the closed chamber. Multiple plates can be arrayed to form multiple chambers, and each chamber's polymerization temperature, as well as resident polymerization mixture, can be individually predetermined. This method and apparatus are particularly useful for preparing polymers used in drag reducing agents for hydrocarbon transportation pipeline applications, as well as other polymers benefiting from narrow and/or customized temperature profiles during production.

Miniaturized reaction apparatus

A stacked plate chemical reactor in which simple plates, each incorporating no surface features other that an opening, are stacked together. When openings in adjacent plates are properly aligned, a fluid pathway is defined between inlet ports for each chemical reactant and an outlet port for a chemical product. In one embodiment of the invention, sixteen simple plates are stacked to provide a reactor incorporating three heat transfer fluid pathways, two reactant fluid pathways, one product fluid pathway, multiple mixing chambers, multiple reaction chambers, two reactant pretreatment heat exchangers, two reaction chamber heat exchangers, and multiple temperature sensor pathways. Precise dimensional control of the reactant fluid pathway height enables stacked laminar flow paths for the reactants to be achieved, allowing efficient and rapid diffusion mixing to occur. Because the simple plates incorporate no features other than openings, fabrication of such plates is easily achieved. Different reactor designs, having additional reactant pathways, more or fewer heat transfer fluid pathways, more or fewer heat exchangers, more or fewer mixing chambers, more of fewer reaction chambers, and more or fewer sensor pathways can readily be achieved by adding or removing plates from the stack, and or by changing the pattern and number of openings in the simple plates that are used. The simple plates can be field in the stack during use of the chemical reactor using pressure exerted on opposite outer simple plates of the stack, or can be permanently joined. A preferred material for the fabrication of the plates is stainless steel, although other materials such as glass, plastic, and other metals can alternatively be used, which are compatible with the selected reactants and the desired product.

Reforming unit and method for converting reagent into reaction products (alternatives)

FIELD: plate- type reforming units. SUBSTANCE: reforming unit is essentially stack of heat-conducting plates with catalytic strips in-between that has inner and outer reagent receivers. Catalytic strip is in direct contact with heat-conducting plates so that its temperature does not actually differ from that of heat-transfer plate; mechanical design of the latter is such that almost isothermal conditions are ensured in plate plane. As an alternative, one or more catalysts may be used and distributed along flow direction in plane of heat-transfer plates. Unit may function as steam reforming or partially oxidizing facility. In case of steam reforming heat energy required for steam reforming is supplied from outside due to radiation and/or heat transfer to heat-conducting plates. Reaction products are carbon oxide, hydrogen, steam, and carbon dioxide. In case of partial oxidation some portion of natural gas is oxidized in the environment of combustion catalyst and reforming catalyst. Reaction products are carbon oxide, hydrogen, steam, and carbon dioxide, Since catalytic strip is in direct thermal contact with heat-conducting plate, excess temperature cannot build up inside stack. Mechanical design of plate may vary to make it suited to various modifications of receivers where one or more inlets and outlets may be provided for reagent admission, preheating, and discharge. EFFECT: reduced space requirement, enhanced efficiency. 36 cl, 8 dwg ея‘ дс ПЧ с» (19) (13) ВИ 2 175 799 ‘”С2 5 МК’ Н 01 М 8/06, С 01 В 3/38 РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ РОССИЙСКОЙ ФЕДЕРАЦИИ (21), (22) Заявка: 98120512/09, 25.03.1997 (71) Заявитель: ЗТЕК КОПЭРЕЙШН (1$) (24) Дата начала действия патента: 25.03.1997 (72) Изобретатель: ХОУГ Итан Д.
