| 5395513 | Fluid bed catalytic upgrading of reformate A continuous process for upgrading reformate feedstock or the like to reduce benzene content and increase octane fuel rating. The improved process comprises maintaining a fluidized bed of regenerable acid solid medium pore zeolite catalyst particles in a ... | 03/07/1995 |
| 5372009 | Cryogenic distillation A cryogenic technique for recovering pure products from a mixture of at least three close-boiling components. A preferred process is provided for separating a hydrocarbon mixture containing an alkene (i.e. ethene or propene), corresponding alkane having t... | 12/13/1994 |
| 5369135 | Controlled microcellular foams of crystalline amorphous polymers Controlled foams of crystalline amorphous polymers include a second phase polymeric material having a transition temperature below that of the matrix polymeric material. The second phase material provides nucleating sites for the growth of gas formed cell... | 11/29/1994 |
| 5360530 | Lubricating oil dewaxing using membrane separation of cold solvent from dewaxed oil and recycle of cold solvent to filter feed A process for solvent dewaxing a waxy oil feed to obtain petroleum oil lubricating stock comprising the steps of contacting a warm waxy oil feed by indirect heat exchange first with cold filtrate, then with refrigerant to crystallize and precipitate the w... | 11/01/1994 |
| 5358675 | Controlling heterogeneous nucleation and growth of foams A method of controlling the nucleation of cells in a polymeric foam material includes blending a matrix material with a second phase material which provides sites for bubble nucleation. The selection of the second phase material controls the size and dens... | 10/25/1994 |
| 5358625 | Lubricating oil dewaxing using membrane separation of cold solvent from dewaxed oil A process for solvent dewaxing a waxy oil feed to produce a lubricating oil by contacting a warm waxy oil feed in counter-current with a cold oil/solvent filtrate stream through a selectively permeable membrane to transfer cold solvent through the membran... | 10/25/1994 |
| 5333730 | Bag pack and system for suspending and dispensing bags Plastic bags made of film are suspended in a pack on a rack having support rods for suspending the bags by their handles. During removal of a lead bag from the pack, adhesive contact causes opening of the next bag.... | 08/02/1994 |
| 5324865 | Di-isopropyl ether production A process for production of diisopropyl ether by conversion of hydrocarbon feedstock containing propene, propane and C2 - light gas components, including the steps of: optionally, prefractionating fresh feedstock containing propene, propane and... | 06/28/1994 |
| 5304675 | Ester derivatives of lower alkene oligomers An ester product consisting essentially of the acylation product of a mixture of near linear aliphatic 1-alkanols, said alkanols containing six to twenty carbon atoms and having a methyl to methylene branch ratio less than 0.25. These novel esters can be ... | 04/19/1994 |
| 5288924 | Process for starting up an olefin hydration reactor A method for starting up a fixed bed propylene hydration reactor containing shape selective metallosilicate catalyst particles for the production of isopropanol and/or diisopropyl ether is disclosed comprising the following sequential steps: contacting a ... | 02/22/1994 |
