Точная регулировка температуры в тепловых зонах осуществляется за счет смешения газа-теплоносителя и газа-разбавителя, поступающих на вход каждой зоны. Перепад температуры в зонах термообработки обеспечивается на уровне не более 5°С. Распределение газообразного теплоносителя в объеме носителя катализатора изомеризации осуществляется за счет газораспределительного устройства, представляющего собой горизонтально расположенную систему конусообразных полых каналов, пронизывающих слой носителя.

Activated carbon blacks and the enhanced methods of preparing activated carbon blacks have been discovered. In order to form an activated carbon black, a conductive carbon black is coated with nanoparticles containing metal, and then catalytically activated in steam and an inert gas to form a catalytically activated mesoporous carbon black, where the mass of the catalytically activated carbon black is lower than the mass of the carbon black. The nanoparticles may serve as catalysts for activation rugosity of mesoporous carbon blacks. The catalytically activated carbon black material may be used in all manner of devices that contain carbon materials.

The present invention concerns a method of preparation of nanoparticular metal oxide catalysts having a narrow particle size distribution. In particular, the invention concerns preparation of nanoparticular metal oxide catalyst precursors comprising combustible crystallization seeds upon which the catalyst metai oxide is co-precipitated with the carrier metal oxide, which crystallization seeds are removed by combustion in a final calcining step. The present invention also concerns processes wherein the nanoparticular metal oxide catalysts of the invention are used, such as SCR (deNOx) reactions of nitrogen oxides with ammonia or urea as reductant, oxidations of alcohols or aldehydes with dioxygen or air to provide aldehydes, ketones or carboxylic acids, and photocatalytic oxidation of volatile organic compounds (VOCs).

Microencapsulated catalyst

Номер: US20120016139A1
Автор: Mohammed Nisar, Thomas Eric Oliver Screen
Принадлежит: REAXA Ltd

The present invention relates to a catalyst system. In particular the invention relates to a catalyst in the form of metal or an alloy that is encapsulated within a polymer shell or matrix. More specifically the invention is directed towards reactive catalytic metals that may be pyrophoric or otherwise reactive in air and/or susceptible to oxidation. In particular, the invention is concerned with catalysts based on nickel. Raney or sponge nickel is highly hazardous: a self-igniting solid; produces hazardous fumes when burning; causes irritation of the respiratory tract, nasal cavities; causes pulmonary fibrosis if inhaled; ingestion may lead to convulsions and intestinal disorders; causes eye and skin irritation; and chronic exposure may lead to pneumonitis and sensitization (“nickel itch”). The invention provides metal catalysts that avoid such problems and have a good shelf life and working life.

A method for producing double-component modified molecular sieve comprises adding molecular sieve to an aqueous solution containing phosphorus to form a mixture, allowing the mixture to react at pH of 1-10, temperature of 70-200° C. and pressure of 0.2-1.2 MPa for 10-200 min, and then filtering, drying and baking the resultant to obtain phosphorus-modified molecular sieve, and then adding the phosphorus-modified molecular sieve to an aqueous solution containing silver ions, allowing the phosphorus-modified molecular sieve to react with silver ions at 0-100° C. in dark condition for 30-150 min, and then filtering, drying and baking. The obtained double-component modified molecular sieve contains 88-99 wt % molecular sieve with a ratio of silica to alumina between 15 and 60, 0.5-10 wt % phosphorus (based on oxides) and 0.01-2 wt % silver (based on oxides), all based on dry matter.

Vertically oriented carbon nanotubes (CNT) arrays have been simultaneously synthesized at relatively low growth temperatures (i.e., <700° C.) on both sides of aluminum foil via plasma enhanced chemical vapor deposition. The resulting CNT arrays were highly dense, and the average CNT diameter in the arrays was approximately 10 nm, A CNT TIM that consist of CNT arrays directly and simultaneously synthesized on both sides of aluminum foil has been fabricated. The TIM is insertable and allows temperature sensitive and/or rough substrates to be interfaced by highly conductive and conformable CNT arrays. The use of metallic foil is economical and may prove favorable in manufacturing due to its wide use.

This present invention provides a method to more efficiently recover hydrogen and carbon dioxide, preferably at least 50%, even more preferably at least 75%, and most preferably at least 90% of the carbon dioxide. The present invention further provides the design for capture of at least 80%, carbon dioxide from syngas that allows for the simultaneous production of medium to high amounts of hydrogen in the syngas as a part of the production of hydrogen in a hydrogen generation plant. By using the process of the present invention, especially in terms of a hydrogen generation plant, it is possible to increase recovery of hydrogen and capture of the carbon dioxide in the syngas stream by balancing the recycle of the hydrogen rich permeate from the hydrogen membrane separation units to the process unit and/or the water gas shift as capacity allows when a carbon dioxide separation unit, a carbon dioxide membrane separation unit and two hydrogen membrane separation units are utilized.
