20080226520 | Airlift Loop Reactor without the Need for External Gases - This invention provides an airlift loop reactor without the need for external gases, which comprises main reactor ( | 09-18-2008 |
20090169446 | System for hydrogen generation - The present invention relates to a composition and method for storage and controlled release of hydrogen. In particular, the present invention relates to the use of borohydride based solutions as a hydrogen storage source and a catalyst system to release hydrogen therefrom. | 07-02-2009 |
20090324465 | Reactor Design for Smaller Batch Transfers of Catalyst - A moving bed of catalyst loses activity as it moves through the reactor. Creating multiple passes for the process fluid moving across a catalyst bed, increases the utilization of the catalyst and creates a pseudo-counter current flow of catalyst and process fluid. The flow improves the temperature profile of the bed and allows higher temperature fluid contacting the less active catalyst. | 12-31-2009 |
20100015020 | METHOD AND APPARATUS FOR REFINING BIODIESEL - Method and apparatus for producing biodiesel fuel, i.e., alkyl ester, from vegetable and/or animal oil. A transesterification catalyst is prepared in a base catalyst tank by spraying alkyl alcohol under pressure through jets at metal hydroxide pellets until the pellets have fully reacted with the alcohol. The oil is heated and transesterified in the presence of alkyl alcohol and the transesterification catalyst in a closed, recirculating transesterification flow system under slight cavitation to yield product alkyl ester and product glycerol. Cavitation is achieved by permitting air to enter the transesterification flow system through an adjustable air inlet valve. When permitted to stand, product alkyl ester forms an upper layer that is decanted and subjected to purification steps, to remove particulates and alkyl alcohol from the product alkyl ester, and a lower layer of product glycerol is drained away. Purification of the product alkyl ester preferably includes subjecting the product alkyl ester to an overhead water mist in a wash tank with simultaneous infusion of a stream of air bubbles. Alcohol vapor is reclaimed as liquid alcohol within an alcohol condenser and stored for reuse. If the oil contains free fatty acids, prior to transesterification, the oil is heated and the free fatty acids are esterified in the presence of an esterification catalyst and alkyl alcohol. For safety, baffles and explosion damper/flame arrestors are provided in locations where flammable vapors pose a risk. | 01-21-2010 |
20100092354 | HIGH SHEAR PROCESS FOR THE PRODUCTION OF CHLORAL - Use of a high shear mechanical device incorporated into a process for the production of chloral as a reactor device is capable of decreasing mass transfer limitations, thereby enhancing the chloral production process. A system for the production of chloral from acetaldehyde and chlorine, the system comprising a reactor and an external high shear device the outlet of which is fluidly connected to the inlet of the reactor; the high shear device capable of providing a dispersion of chlorine gas bubbles within a liquid, the bubbles having an average bubble diameter of less than about 100 μm. | 04-15-2010 |
20140186233 | DUST SEPARATING AND CARRIER RETURNING DEVICE - Disclosed is a dust separating and carrier returning device, which comprises: an outer raw material transfer passage ( | 07-03-2014 |
422235000 | And means heating or cooling loop or reaction mass located therein | 1 |
20110135544 | Apparatus For The Hydroformylation Of Olefins - The present invention relates to a method for preparing aldehydes by reacting olefins with a synthesis gas including carbon monoxide and hydrogen, and to an apparatus therefore. More particularly, the present invention relates to a method for preparing aldehydes, characterized by spraying and supplying olefins, synthesis gas including carbon monoxide and hydrogen, and a catalyst composition into an oxo reactor through a nozzle, and to an apparatus therefore. According to the present invention, the hydroformylation efficiency can be improved, thereby obtaining desirable aldehydes with a high yield. | 06-09-2011 |
