摘要： Cationic layered materials, a process for their preparation and their use in hydrocarbon conversion, purification, and synthesis processes, such as fluid catalytic cracking. Cationic layered materials are especially suitable for the reduction of SOx and NOx emissions and the reduction of the sulfur and nitrogen content in fuels like gasoline and diesel. The new preparation process avoids the use of metal salts and does not require the formation of anionic clay as an intermediate.

摘要： The present invention is directed to a process for the preparation of crystalline anionic clay-containing bodies from sources comprising a trivalent metal source and a divalent metal source comprising the steps of: a) preparing a precursor mixture containing a liquid, a divalent metal source and/or a trivalent metal source, at least one of them being insoluble in the liquid; b) shaping the precursor mixture to obtain shaped bodies; c) optionally thermally treating the shaped bodies; and d) aging the shaped bodies to obtain crystalline anionic clay-containing bodies; with the proviso that if no divalent or trivalent metal source is present in the precursor mixture of step a), such source is added to the shaped bodies after shaping step b) and before aging step d); and with the further proviso that the combined use of an aluminium source as the trivalent metal source and a magnesium source as the divalent metal source is excluded. The quintessence of the present invention is that the major part of the final amount of anionic clay is formed after shaping, i.e., in situ in the shaped body. This results in attrition resistant bodies, without the need to add a binder material.

摘要： The invention pertains to a continuous process for the conversion of inorganic solid starting particles which either are amorphous or possess a degree of order into inorganic solid product particles which when the starting particles are amorphous, possess a degree of order, or when the starting particles possess a degree of order, possess a different order, a different degree of order, or no order, which product particles are suitable for use in or as a catalyst, in or as a carrier, or in or as an adsorbent, in which process the starting particles are dispersed in a liquid thus forming a suspension. The suspension flows through at least two separate conversion vessels (3) which are connected in series and the suspension is agitated in each of these vessels (3). The invention furthermore relates to an apparatus suitable for carrying out the process according to the invention. This invention allows the processing of suspension with a high Solids to Liquid Ratio. The conversion vessels are decoupled by one or more of the process conditions in one or more of the conversion vessels differing from those in the other vessel or vessels.

摘要： A method of serially transferring annihilation information in a compact positron emission tomography (PET) scanner includes generating a time signal representing a time-of-occurrence of an annihilation event, generating an address signal representing a channel detecting the annihilation event, and generating a channel signal including the time and address signals. The method also includes generating a composite signal including the channel signal and another similarly generated channel signal concerning another annihilation event. An apparatus that serially transfers annihilation information includes a time signal generator, address signal generator, channel signal generator, and composite signal generator. The time signal is asynchronous and the address signal is synchronous to a clock signal. A PET scanner includes a scintillation array, detection array, front-end array, and a serial encoder. The serial encoders include the time signal generator, address signal generator, channel signal generator, and composite signal generator.

摘要： A digital video recorder employing standard hard disk arrays employs a caching system to enable continuous video data to be supplied to and provided from the standard disk drives which may not be adapted for continuous data stream operation. The system is implemented as an array of disk drives and includes cache management functions for governing disk read and write operations. A predictor enables the cache to predict disk reads and disk writes and to maintain the cache based on the predictions. Redundancy enables playback in the event of failure of a drive in the array and also provides improved playback data retrieval time.
