208262100 | Halogen contaminant removal | 7 |
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 |
20100032346 | Process for Reducing Bromine Index of Hydrocarbon Feedstock - The present invention relates to a process for reducing the Bromine Index of a hydrocarbon feedstock having at least 50 wt. % of C | 02-11-2010 |
20100270212 | Start Up Procedure in a Process for Purifying Aromatic Streams - A process for the purification of aromatic streams is provided that includes a new start up procedure that in embodiments significantly reduces impurities in an aromatics feedstock. | 10-28-2010 |
20100282641 | Process for Reducing Bromine Index of Hydrocarbon Feedstocks - A process for reducing the Bromine Index of a hydrocarbon feedstock, the process comprising the step of contacting the hydrocarbon feedstock with a catalyst at conversion conditions, wherein the catalyst includes at least one molecular sieve and at least one clay, and wherein said catalyst is sufficient to reduce more than 50% of the Bromine Index of a hydrocarbon feedstock. | 11-11-2010 |
20100320125 | REDUCTION OF ORGANIC HALIDE CONTAMINATION IN HYDROCARBON PRODUCTS - A method for reducing halide concentration in a hydrocarbon product having an organic halide content from 50 to 4000 ppm which is made by a hydrocarbon conversion process selected from the group consisting of polymerization, dimerization, oligomerization, acetylation, metatheses, copolymerization, isomerization, olefin hydrogenation, hydroformylation, and combinations thereof, using an ionic liquid catalyst comprising a halogen-containing acidic ionic liquid, comprising contacting at least a portion of the hydrocarbon product with at least one molecular sieve having a pore size from 4 to 16 Angstrom under organic halide absorption conditions, wherein the organic halide is absorbed during the contacting, to reduce the halogen concentration in the hydrocarbon product to less than 40 ppm. | 12-23-2010 |
20120325724 | RECOVERY OF ALKYL CHLORIDE ADSORBTION CAPACITY BY BASIC SOLUTION TREATMENT OF SPENT ADSORBENT - Processes for the rejuvenation of a spent adsorbent, wherein the adsorption capacity of the spent adsorbent may be repeatedly restored by treating the spent adsorbent with a basic solution and subsequent adsorbent activation, thereby allowing a plurality of adsorption cycles using a single adsorbent sample. Processes for ionic liquid catalyzed hydrocarbon conversion and hydrocarbon product purification are also disclosed. | 12-27-2012 |
20150053589 | HYDROCARBON HYDROTREATING DEVICE AND METHOD FOR REMOVING CHLORIDE FROM A HYDROCARBON STREAM - A method for processing hydrocarbons includes providing a hydrocarbon stream including chlorides from one or more of a crude, vacuum or coker column and contacting the provided hydrocarbon stream with an adsorbent capable of adsorbing the chlorides from the hydrocarbon stream. The dechlorinated hydrocarbon stream is then provided to a hydrotreater reactor. | 02-26-2015 |
