20100258505 | PROCESS AND APPARATUS FOR SIMULATED MOVING BED SEPARATION COMPRISING BYPASS LINES IN EVERY OTHER BED AND WITH A MODULATED BYPASS FLUID FLOW RATE - A process for separating a feed F by simulated moving bed adsorption in a SMB device is described, the device comprising external bypass lines L | 10-14-2010 |
20100311566 | PROCESS FOR REGENERATING A REFORMING CATALYST - The invention concerns a process for regenerating a catalyst for the production of aromatic hydrocarbons or for reforming. Said process comprises a step for combustion in a zone A comprising at least 2 beds A | 12-09-2010 |
20100314288 | PROCESS FOR PRE-GENERATIVE REFORMING OF GASOLINES, COMPRISING RECYCLING AT LEAST A PORTION OF THE EFFLUENT FROM THE CATALYST REDUCTION PHASE - The present invention describes a process for regenerative reforming of gasolines, characterized by recycling at least a portion of the effluent from the catalyst reduction zone to the head of the last or penultimate reactor of the reaction zone. This arrangement can significantly improve the hydrogen balance of the unit and the production of reformate. | 12-16-2010 |
20110201865 | PROCESS AND DEVICE FOR SIMULATED MOVING BED SEPARATION WITH A MODULATED BY-PASS FLUID FLOW - A process for separating a feed F by simulated moving bed adsorption in a SMB device comprises at least one zone 1 for desorption of the compounds produced in the extract, a zone 2 for desorption of the compounds produced in the raffinate, a zone 3 for adsorption of the compounds produced in the extract, a zone 4 located between the raffinate withdrawal and the desorbant supply, the device comprising external by-pass lines L | 08-18-2011 |
20140027348 | CONTINUOUS CATALYST REGENERATION REACTOR WITH A CHAMBER FOR MIXING GAS AND DISTRIBUTING GAS IN THE OXYCHLORINATION ZONE - A reactor for regenerating catalyst grains comprises a vessel having an oxychlorination zone superimposed over a calcining zone having a line for introducing gas. A chamber, disposed between oxychlorination and calcining zones, comprises an internal space located between two plates which are gas tight and impervious to catalyst grains. A plurality of tubes pass through the chamber to allow catalyst to pass from oxychlorination zone to calcining zone. A plurality of means pass through the chamber to allow calcining gas to pass from calcining zone to oxychlorination zone. At least one oxychlorination gas injection line opens into the internal space of the chamber. Each means for passage of calcining gas comprises at least one orifice communicating with the chamber internal space, and a means for evacuating gas which is permeable to gas and impermeable to catalyst grains. | 01-30-2014 |
20140027349 | REACTOR FOR CONTINUOUS CATALYST REGENERATION WITH A PERFORATED BOX FOR MIXING AND DISTRIBUTING GASES IN THE OXYCHLORINATION ZONE - A reactor allowing continuous regeneration of catalyst grains having a chamber with an oxychlorination zone superposed on a calcination zone equipped with a pipe for introducing calcination gas and at least one pipe for injecting oxychlorination gas emptying into the inner space. Each gas passage has a gas evacuation device that is permeable to gas and impermeable to catalyst grains. | 01-30-2014 |
