20100081564 | PROTECTION OF SOLID ACID CATALYSTS FROM DAMAGE BY VOLATILE SPECIES - The invention provides a method to avoid catalyst damage and achieve longer catalyst life by selecting appropriate materials for reactor spacers, liners, catalyst binders, and supports, in particular, by not using crystalline silica-containing and high phosphorus-containing materials, if the presence of even small amount of steam is anticipated. In addition, alkali metals and alkaline earth metals are avoided due to potential damage to the catalyst. | 04-01-2010 |
20110027141 | Aromatics Co-Production in a Methanol-to-Propylene Unit - The present invention provides a reactor system having: (1) a first reactor receiving an oxygenate component and a hydrocarbon component and capable of converting the oxygenate component into a light olefin and the hydrocarbon component into alkyl aromatic compounds; (2) a separator system for providing a first product stream containing a C | 02-03-2011 |
20110028771 | Aromatics Co-Production in a Methanol-to-Propylene Unit - The present invention provides a reactor system having: (1) a first reactor receiving an oxygenate component and a hydrocarbon component and capable of converting the oxygenate component into a light olefin and the hydrocarbon component into alkyl aromatic compounds; (2) a separator system for providing a first product stream containing a C | 02-03-2011 |
20110143919 | OCP Catalyst With Improved Steam Tolerance - A catalyst is present for use in an olefin cracking process. The catalyst is a zeolite that has been loaded with an alkaline earth metal. The alkaline earth metal loaded catalyst has an increased steaming tolerance and increases the useful life of the catalyst during the cracking process and the regeneration cycle. | 06-16-2011 |
20110230333 | Olefin Cracking Catalyst and Manufacturing Process - A new catalyst and method of preparing the catalyst is presented. The catalyst is a molecular sieve used for cracking olefins, and has improved selectivity to increase propylene yields and to reduce the amount of aromatics and methane produced. The catalyst been ion-exchanged to reduce the alkali composition in the catalyst. | 09-22-2011 |
20140163280 | CONVERSION OF METHANE TO AROMATIC COMPOUNDS USING UZM-44 ALUMINOSILICATE ZEOLITE - A new family of aluminosilicate zeolites designated UZM-44 has been synthesized. These zeolites are represented by the empirical formula. | 06-12-2014 |
20140163281 | CONVERSION OF METHANE TO AROMATIC COMPOUNDS USING A CATALYTIC COMPOSITE - A catalyst for the conversion of at least one low carbon number aliphatic hydrocarbon in a feedstream to provide at least one aromatic hydrocarbon, the catalyst comprising a zeolite and a promoter metal M, the zeolite characterized by the retention of greater than 40% of the tetrahedral aluminum sites in the zeolite following calcination of the catalyst in air at 750° C. for 3 hours when compared to the amount of tetrahedral aluminum in the same catalyst after calcination in air at 500° C. for 3 hours. | 06-12-2014 |
20140163282 | CONVERSION OF METHANE TO AROMATIC COMPOUNDS USING UZM-39 ALUMINOSILICATE ZEOLITE - A new family of coherently grown composites of TUN and IMF zeotypes has been synthesized and shown to be effective catalysts in processes for converting at least one aliphatic hydrocarbon having from 1 to about 4 carbon atoms in a feedstream to provide at least one aromatic hydrocarbon. These zeolites are represented by the empirical formula. | 06-12-2014 |
