Abstract: An apparatus and method are provided for storing a plurality of translation entries in a cache, each translation entry corresponding to one of a plurality of page table entries and defining a translation between a first address and a second address, and encoding control information indicative of an attribute of each page table entry; returning, in response to a lookup querying a first lookup address, a corresponding second address when the first lookup address corresponds to one of the plurality of translation entries stored in the cache; modifying at least some of the control information in response to notification of a modification of the attribute in a page table entry; and retaining in the cache at least one translation entry corresponding to the page table entry for use in a subsequent address lookup querying a corresponding first lookup address in response to the notification of the modification of the attribute in the page table entry.

Abstract: A method is described for preparing a sorbent comprising the steps of: (i) forming agglomerates comprising a particulate support material, (ii) coating the agglomerates with a coating mixture powder comprising a particulate copper sulphide and a particulate calcined, rehydratable alumina to form a coated agglomerate, and (iii) drying the coated agglomerate to form a dried sorbent.

Abstract: A method is described for preparing a sorbent comprising the steps of: (i) mixing together a particulate copper sulphide material and a particulate calcined rehydratable alumina, (ii) shaping the mixture, and (iii) drying the shaped mixture to form a dried sorbent.

Abstract: A method is described for preparing a sorbent precursor comprising the steps of: (i) forming agglomerates comprising a particulate support material, (ii) coating the agglomerates with a coating mixture powder comprising a particulate sulphidable copper compound and a particulate calcined, rehydratable alumina to form a coated agglomerate, and (iii) drying the coated agglomerate to form a dried sorbent precursor. The sorbent precursor may be sulphided and used to remove heavy metals such as mercury from fluid streams.

Abstract: A sorbent precursor is described comprising agglomerates of an inert particulate support material, the agglomerates being bound together with a binder comprising cement and/or clay, said binder being characterized as an agglomerate binder, wherein (a) the agglomerates are coated with a surface layer coating comprising a particulate copper compound and one or more coating binders, and (b) the surface layer has a thickness in a range of from 1 to 1000 ?m. The sorbent precursor may be sulphided to prepare a sorbent for removing heavy metals from fluid streams.
