20100230361 | MERCURY REMOVAL - A mercury absorbent comprising a metal sulphide, a support material, a first binder and a second binder, wherein the first binder is a cement binder and the second binder is a high aspect ratio binder having an aspect ratio >2. A mercury removal process comprises contacting a mercury containing feed stream with the absorbent. | 09-16-2010 |
20100320153 | ABSORBENTS - An absorbent composition suitable for removing mercury, arsenic or antimony from fluid streams includes 5-50% by weight of a particulate sulphided copper compound, 30-90% by weight of a particulate support material, and the remainder one or more binders, wherein the metal sulphide content of the absorbent, other than copper sulphide, is below 5% by weight. | 12-23-2010 |
20110226700 | REDUCED COPPER SULPHIDE SORBENT FOR REMOVING HEAVY METALS - A sorbent, suitable for removing heavy metals, particularly mercury, from fluid streams containing a reductant such as hydrogen and/or carbon monoxide, is in the form of a shaped unit containing ≦0.1% by weight in total of heavy metal selected from mercury, arsenic, lead, cadmium and antimony, and 4-75% by weight of copper in the form of one or more reduced copper sulphides which have a sulphur to copper atomic ratio of ≦0.6:1. | 09-22-2011 |
20120103912 | MIXED VALENCY METAL SULFIDE SORBENTS FOR HEAVY METALS - A sorbent, suitable for removing heavy metals, including mercury, from fluids containing hydrogen and/or carbon monoxide at temperatures up to 550° C., in the form of a shaped unit comprising one or more mixed-valency metal sulphides of vanadium, chromium, manganese, iron, cobalt or nickel. | 05-03-2012 |
20120199538 | SULPHUR REMOVAL - A process for desulfurizing a process fluid includes contacting a sulphur compound containing feed stream with an absorbent including an iron, copper or nickel compound capable of forming a metal sulphide, a support material, a first binder and a second binder where the first binder is a cement binder and the second binder is a high aspect ratio aluminosilicate clay binder having an aspect ratio >2 and a ratio of the first binder to the second binder is in the range 2:1 to 3:1. | 08-09-2012 |

20140296607 | PURIFICATION PROCESS - A process for removing halogen compounds, particularly chlorine compounds, from a process fluid, includes the steps of (i) passing a process fluid containing hydrogen halide over a first sorbent to remove hydrogen halide and generate a hydrogen halide depleted process fluid and then, (ii) passing the hydrogen halide depleted process fluid over a second different sorbent to remove organic halide compounds therefrom. A purification system suitable for removing hydrogen halide and organic halide compounds from process fluids is also described. | 10-02-2014 |
20150060729 | METHOD FOR PRODUCING A SULPHIDED COPPER SORBENT - A method for producing a sulphided copper sorbent includes the steps of: (i) contacting a sorbent precursor material containing one or more sulphidable copper compounds, with a sulphiding gas stream including hydrogen sulphide to form a sulphided sulphur-containing sorbent material, and (ii) subjecting the sulphided sulphur-containing sorbent material to a heating step in which it is heated to a temperature above that used in the sulphiding step and ≧110° C., under an inert gas selected from nitrogen, argon, helium, carbon dioxide, methane, and mixtures thereof, the inert gas optionally including hydrogen sulphide. The method provides sulphided copper sorbents that have reduced levels of elemental sulphur. | 03-05-2015 |
