This invention relates to hydrocracking catalysts utilizing 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. This invention also relates to the use of such catalysts in hydrocracking processes for the conversion of heavy oils into lighter fuel products. The invention is particularly suited for the selective production of diesel range products from gas oil range feedstock materials under hydrocracking conditions.

This invention relates to a catalyst and method for hydrodesulfurizing naphtha. More particularly, a Co/Mo metal hydrogenation component is loaded on a high temperature alumina support in the presence of a dispersion aid to produce a catalyst that is then used for hydrodesulfurizing naphtha. The high temperature alumina support has a defined surface area that minimizes olefin saturation.

This invention relates to the composition, method of making and use of a fluidized catalytic cracking (“FCC”) catalyst that is comprised of a new Y zeolite which exhibits an exceptionally low small mesoporous peak around the 40 Å (angstrom) range as determined by nitrogen adsorption measurements. FCC catalysts made from this new zeolite exhibit improved rates of heavy oil cracking heavy oil bottoms conversions and gasoline conversions. The fluidized catalytic cracking catalysts herein are particularly useful in fluidized catalytic cracking (“FCC”) processes for conversion of heavy hydrocarbon feedstocks such as gas oils and vacuum tower bottoms.

A vehicle-dispatching system includes a service center and a plurality of hosts disposed in respective vehicles. For equally distributing the chances of accepting a reserved vehicle service task, a vehicle-dispatching method is provided. Firstly, the service center is in communication with the hosts of respective vehicles, thereby establishing a database and a dispatching priority ranking table. When the service center receives a vehicle service request, a vehicle is selected from the database according to the dispatching priority ranking table. If the host of the selected vehicle receives the inquiry signal and consents to accept a vehicle service task, a vehicle service confirming signal is issued from the host of the selected vehicle. When the service center receives the vehicle service confirming signal from the host of the selected vehicle, the host of the selected vehicle is adjusted to a lower priority ranking in the dispatching priority ranking table.

An automatic chauffeured vehicle dispatch system and method are disclosed. In the vehicle dispatch system, audio signals and an automated management system are used. The automatic chauffeured vehicle dispatch system of the present invention comprises a service system, a dispatch system, a dispatch center server, an address analysis module, a databank server and a voice conversion module. The dispatch center server is connected with a telecommunication network, the internet, a databank server, a voice conversion module, the service system and the dispatch system. The address analysis module is able to analyze patrons' addresses and store the addresses in the databank server in the order of frequency of use. The voice conversion module is connected with the databank server and is able to covert the addresses stored in the databank server into audio signals, which may be sent to clients via the dispatch center server and a communication network.
摘要:
The invention relates to a catalyst for hydrodesulfurizing naphtha, to a method for preparing said catalyst and to a method for hydrodesulfurizing naphtha using said catalyst. More particularly, the catalyst comprises a Co/Mo metal hydrogenation component on a silica support having a defined pore size distribution and at least one organic additive. The catalyst has high dehydrosulphurisation activity and minimal olefin saturation when used to hydrodesulfurize FCC naphtha.

This invention relates to the composition and synthesis of an Extra Mesoporous Y (or “EMY”) zeolite and its use in the catalytic conversion of organic compounds. In particular, this invention relates to a Y-type framework zeolite possessing a high large mesopore pore volume to small mesopore pore volume ratio. The novel zeolite obtained provides beneficial structural features for use in petroleum refining and petrochemical processes.
摘要:
In a method of forming a shaped body, a mixture is formed comprising a particulate silica-rich material, water and a potassium base or basic salt, wherein the total solids content of the mixture is from about 20 to about 90 weight percent. The mixture is extruded into extrudates and the extrudates are dried and heated to a temperature of from about 300° C. to about 800° C. to form the shaped body.
