Patent application number | Description | Published |
20090176643 | Sour service dewaxing catalyst without separate hydrogenation function - Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include a zeolite with a low silica to alumina ratio combined with a low surface binder, or alternatively the formulated catalyst has a high ratio of zeolite surface area to external surface area. | 07-09-2009 |
20090206004 | Aromatic hydrogenation process - An MCM-41 catalyst having a crystalline framework containing SiO | 08-20-2009 |
20090215612 | Aromatic hydrogenation catalysts - An MCM-41 catalyst having a crystalline framework containing SiO | 08-27-2009 |
20100075831 | Multiple molecular sieve catalyst for sour service dewaxing - Catalysts for dewaxing of hydrocarbon feeds, particularly feeds with elevated sulfur and nitrogen levels, are provided. The dewaxing catalysts include at least two zeolites, including a zeolite with a low silica to alumina ratio. The catalysts may be combined with a low surface binder, or alternatively the catalysts as formulated may have a high ratio of zeolite surface area to external surface area. | 03-25-2010 |
20100187156 | Sour service hydroprocessing for lubricant base oil production - An integrated process for producing lubricant base oils from feedstocks under sour conditions is provided. The ability to process feedstocks under higher sulfur conditions allows for reduced cost processing and increases the flexibility in selecting a suitable feedstock. The sour feed can be delivered to a catalytic dewaxing step without any separation of sulfur and nitrogen contaminants, or a high pressure separation can be used to partially eliminate contaminants. | 07-29-2010 |
20130142717 | OFFSHORE GAS SEPARATION PROCESS - A process for the selective absorption of normally gaseous acid components from hydrocarbon gas mixtures containing both the acidic components and gaseous non-acidic components which is carried out in a gas separation unit located at an offshore marine production installation. The sorbent used in the process comprises a severely sterically hindered amino ether. The process is capable of selectively removing H | 06-06-2013 |
20130309129 | INHIBITION OF CORROSION IN BOILER SYSTEMS WITH ETHERAMINES - Aminoethers are used as corrosion inhibitors in boiler systems in which a working fluid comprising water with an aminoether corrosion inhibitor is circulated from a heater to a utilization site at which the working fluid gives up energy and decreases in temperature. A preferred class of aminoethers are the alkoxytriethyleneglycol-tert-alkylamines such as methoxy triethyleneglycol-tert-butylamine. | 11-21-2013 |
20130310623 | AMINE GAS TREATMENT SOLUTIONS - A process for the selective absorption of acidic components from normally gaseous hydrocarbon mixtures using an aqueous amine absorbent solution comprising an antioxidant and a non-detergent co-solvent for the amine and the antioxidant. | 11-21-2013 |
