In a process for producing cyclohexylbenzene, benzene is reacted with cyclohexene in a first reaction zone under conditions effective to produce a reaction product comprising cyclohexylbenzene and at least one polycyclohexylbenzene. At least a portion of the reaction product and a stripping agent comprising at least one C1 to C11 hydrocarbon or hydrogen are then separately supplied to a separation device and separated into at least a first fraction rich in cyclohexylbenzene and a second fraction rich in the at least one polycyclohexylbenzene.

In a process for producing a cycloalkylaromatic compound, an aromatic compound and a cyclic olefin are contacted with a first catalyst under conditions effective to produce a reaction product comprising the cycloalkylaromatic compound and at least one non-fused bicyclic by-product. The at least one non-fused bicyclic by-product is then contacted with a second catalyst under conditions effective to convert at least a portion of the at least one non-fused bicyclic by-product to a converted by-product.

This invention relates to stabilized aggregates of small primary crystallites of zeolite Y that are clustered into larger secondary particles. At least 80% of the secondary particles may comprise at least 5 primary crystallites. The size of the primary crystallites may be at most about 0.5 micron, or at most about 0.3 micron, and the size of the secondary particles may be at least about 0.8 micron, or at least about 1.0 μm. The silica to alumina ratio of the resulting stabilized aggregated Y zeolite may be 4:1 or more.

In a process for producing cyclohexylbenzene hydroperoxide, cyclohexylbenzene is contacted with oxygen to produce a reaction product comprising cyclohexylbenzene hydroperoxide and unreacted cyclohexylbenzene. The reaction product is then maintained under conditions such that crystals of cyclohexylbenzene hydroperoxide form and separate from the reaction product. The cyclohexylbenzene hydroperoxide crystals are then recovered from the reaction product.

This invention provides a request controlling apparatus, processor and method. The request controlling apparatus is connected to a request storage unit and includes: a queue unit storing flag recording region configured to record a storing flag corresponding to a queue unit in the request storage unit, a comparing means configured to judge whether a incoming first queue unit corresponds to a same message as an already existing queue unit, where the already existing queue unit is in the request storage unit and a flag setting means is configured to set the storing flag corresponding to the already existing queue unit in the queue unit storing flag recording region, to indicate that a message state related to the already existing queue unit will not be stored if the first queue unit corresponds to the same message as in the already existing queue unit.

This invention relates to aggregates of small particles of synthetic faujasite zeolite. Small primary particles of zeolite are clustered into larger secondary particles. The observable average width of the primary particles may be 0.3 micron or less and the observable average width of the secondary particles may be 0.8 micron or more. The silica to alumina ratio of the zeolite may be less than 4:1.

A processing unit coupled to a bus for accelerating data transmission and a method for accelerating data transmission. The present invention provides a streaming data transmission mode in which a plurality of data blocks are transmitted via one handshake. The present invention employs handshake save policy, when a processing unit sends a request comprising a plurality of data blocks on a bus, a cache or memory will perform address matching to judge whether there is any hit data block. If there is any hit data block, the cache or memory only needs to reply once and then start to continuously transmit the hit data blocks it possesses. Thus, a separate handshake for each data block is no longer needed.

An automatic filling termination device and a cryogenic vessel are provided including a body with a chamber, defined in the cryogenic vessel and provided with an inlet, communicated with the inlet for filling cryogenic medium into the chamber, and an outlet, arranged on the top wall of the body for discharging the cryogenic medium in the chamber into the cryogenic vessel; a flow termination member blocking the outlet, defined in the chamber of the body and has a predetermined weight to not be floated in the cryogenic medium; a floater, located outside the body and moving up and down when the liquid level of the cryogenic medium as filled into the cryogenic vessel is changed; and a connection, penetrated through the outlet to connect the flow termination member with the floater, wherein the outlet internal diameter is greater than the connection outer diameter by a predetermined dimension.
摘要:
A mesoporous oxide composition includes, other than oxygen, a major amount of aluminum and lesser amounts of phosphorus and at least one rare earth element. The compositions have high surface area and excellent thermal and hydrothermal stability, with a relatively narrow pore size distribution in the mesoporous range. These compositions may be prepared by a hydrothermal co-precipitation method using an organic templating agent. These mesoporous oxide compositions may be used as catalysts or as supports for catalysts, for example, in a fluid catalytic cracking process.
