20090266745 | METHOD FOR REMOVING HYDROFLUORIC ACID AND ORGANIC FLUORIDES FROM A FLUID STREAM - A method is provided for removing HF and organic fluorides from fluid streams in which the fluoride species exist as impurities and, in particular, from hydrocarbon fluid streams containing no more than about 1.0% by weight total fluorides. The method consists of first contacting the fluid stream first with a nonpromoted alumina and then with an adsorbent consisting essentially of activated alumina that has been treated with a promoter material selected from the oxides and phosphates of alkali metals and alkaline earth metals, and mixtures thereof. This is preferably accomplished by providing a suitable absorber vessel charged with the adsorbent in a fixed bed, and then contacting the fluoride-contaminated fluid through the fixed bed. | 10-29-2009 |
20100005964 | REGENERATIVE REMOVAL OF TRACE CARBON MONOXIDE - By the present invention, a process is provided to use a modified clinoptilolite adsorbent suitable for the separation of carbon monoxide from hydrogen and hydrocarbon streams without adsorbing hydrocarbons such as paraffins and olefins. In typical applications in platforming units within refineries, these hydrogen streams contain from 5 to 20 parts per million of carbon monoxide. In other applications the level of carbon monoxide may be higher. The separation of carbon monoxide from the hydrogen stream is achieved by using a clinoptilolite molecular sieve that has been ion-exchanged with at least one cation selected from lithium, sodium, potassium, calcium, barium, and magnesium. | 01-14-2010 |
20100222215 | HALIDE SCAVENGERS FOR HIGH TEMPERATURE APPLICATIONS - A composite sorbent is formed which is the reaction product of a solid alkali metal carbonate, rehydratable alumina and water or an aqueous solution of a metal salt. The reaction between the components occurs while forming particulates followed by curing and activation at high temperatures. The alkali metal in the sorbent exhibits a highly reactive and accessible state that is very favorable for various sorption applications. The sorbent is especially useful for removal of HCl and other acid contaminants from gas and liquid hydrocarbon streams at high temperatures. | 09-02-2010 |
20100326886 | LIGHT PARAFFIN ISOMERIZATION WITH IMPROVED FEED PURIFICATION - The service life and deactivation rate of a paraffin isomerization catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water and deactivation of an isomerization catalyst is practically eliminated. The fact that the guard bed material preserves the active metal phase-copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product. | 12-30-2010 |
