    摘要: This invention relates to a treated pillared clay made by the process comprising the steps of:(A) contacting at least one clay with an effective amount of at least one ammonium ion source to exchange sodium and/or calcium ions in said clay for ammonium ions to provide an ammonium-containing clay, said clay comprising metal oxides and hydroxides and having a lamellar structure with lamellar layers and interlamellar spaces disposed between the lamellar layers and exchangeable sodium and/or calcium ions occupying said interlamellar spaces;(B) contacting said ammonium-containing clay with an effective amount of at least one source of fluorine to replace at least part of the hydroxyl groups in said clay with fluorine to provide a fluorine- and ammonium-containing clay;(C) contacting said fluorine- and ammonium-containing clay with an effective amount of at least one pillaring agent to form a fluorine-containing pillared clay; and(D) contacting said fluorine-containing pillared clay with an effective amount of at least one inorganic acid to impregnate and/or incorporate at least part of said acid on said clay.This invention also relates to a process for making the foregoing treated pillared clays. This invention also relates to the use of these treated pillared clays as alkylation catalysts.

    摘要: A system and method for arbitrating among memory requests. According to a preferred embodiment, the system comprises a global memory and a plurality of datapaths. Each datapath comprises a datapath processor for executing instructions of an instruction sequence and for providing a plurality of memory request signal types in accordance with the instructions, wherein the plurality of memory request signal types comprises instruction memory request signals, scalar memory request signals, first-in and first-out memory request signals, statistical decoder memory request signals, and block transfer memory request signals. Each datapath also comprises local memory, a global port for transferring data between the local memory and the global memory, and a dual port comprising first and second local ports for transferring data between the local memory and the datapath processor, wherein the first and second local ports permit simultaneous transfer of data between the local memory and the datapath processor. The system comprises a data bus coupled to the global memory for transferring data to and from the global memory, and a transfer controller for controlling block transfer and scalar data transfers between the local memory and the global memory over the data bus and for arbitrating among competing datapaths of the plurality of datapaths to grant to a selected datapath access to the data bus in accordance with the signal types of the memory request signals generated by datapaths of the plurality of datapaths.
