| Number | Title | Issue Date |
| 7919662 | Process for the dissociation of MTBE Isobutene is prepared by dissociation of MTBE in the gas phase, by a) fractional distillation of an MTBE-containing stream comprising feed MTBE (I) and a recycle stream (VIII) to give an MTBE-containing overhead stream (II) and a bottom stream (III) having a boiling... | 04/05/2011 |
| 7087804 | Use of waste nitrogen from air separation units for blanketing cargo and ballast tanks The present invention relates to the use of a primarily nitrogen containing blanketing agent from the air separation unit of a Gas To Liquids, Heavy Hydrocarbon Conversion, or Methanol Synthesis Facility on transport vessels. The primarily nitrogen containing blanke... | 08/08/2006 |
| 4937059 | Absorption and desorption of carbon dioxide A process for absorption and subsequent desorption of carbon dioxide comprises contacting a CO2 -containing gas with a solid sorbent comprising alkali metal oxide and/or hydroxide (preferably LiOH) and lanthanum oxide. The used solid sorbent ca... | 06/26/1990 |
| 4096198 | Integrated process for regenerating fluorosulfuric acid catalyst An integrated process for regenerating a deactivated or partially deactivated alkylation catalyst comprising fluorosulfuric acid which comprises: (1) contacting said fluorosulfuric acid with water to form an acid-water mixture, thereby converting at least... | 06/20/1978 |
| 4096199 | Process for regenerating fluorosulfuric acid catalyst A process for regenerating an alkylation catalyst comprising fluorosulfuric acid, said catalyst being at least partially deactivated, which comprises: (1) contacting at least a portion of the fluorosulfuric acid with water to form an acid-water mixture, thereb... | 06/20/1978 |
| 4096197 | Process for regenerating fluorosulfuric acid catalyst An improved process for regenerating an alkylation catalyst comprising fluorosulfuric acid, said catalyst being at least partially deactivated, which comprises the method of: (1) removing a portion of the fluorosulfuric acid from said catalyst by contacti... | 06/20/1978 |
| 4048251 | Autorefrigerated isomerization process Acyclic and alicyclic aliphatic hydrocarbons are isomerized to form a product of enhanced octane by contacting same, in a reaction zone and in the presence of hydrogen, with a catalyst comprising a difficultly reducible metal halide in combination with at... | 09/13/1977 |
| 3988385 | Process for producing ethyl fluoride product and alkylate product in HF alkylation The overhead stream of a deisobutanizer in an HF-alkylation plant is extracted with HF to produce a stream containing isobutane, HF and ethyl fluoride, which in turn is fractionated under a pressure of about 150 to 300 psig. The bottoms stream of this fra... | 10/26/1976 |
| 3979475 | Recovery of HF and ethyl fluoride from alkylation of isoparaffin with olefins in presence of HF catalyst Lean HF is used to extract ethyl fluoride from depropanizer overhead by steps including contacting liquid propane containing ethyl fluoride with lean HF thus taking ethyl fluoride into the HF phase, contacting vent gas from the depropanizer overhead with ... | 09/07/1976 |
| 3972956 | Avoiding pollution by HF catalyst residues in alkylation A used HF catalyst rerun unit comprises in tandem at least two strippers, a first to remove substantially all readily vaporizable components, e.g., light hydrocarbons and HF, and to separate acid-soluble oils as a liquid residue, and a second to produce r... | 08/03/1976 |
| 3931352 | HF acid treating the paraffin feed stream to an integrated paraffin isomerization-alkylation process The normal paraffin feed stream to an integrated paraffin isomerization-HF acid-catalyzed alkylation process is treated for the removal of catalyst deactivating sulfur and nitrogen compounds and water by contacting the feed stream with liquid hydrofluoric... | 01/06/1976 |
