20090134065 | Pentasil Catalyst for Light Olefins in Fluidized Catalytic Units - The catalyst of this invention is capable of enhancing light olefin, e.g., propylene, yields in fluidizable catalytic cracking (FCC) processes. The catalyst comprises (a) pentasil zeolite, (b) at least 5% by weight phosphorus (P | 05-28-2009 |
20100010279 | Catalyst Compositions Comprising Metal Phosphate Bound Zeolite and Methods of Using Same to Catalytically Crack Hydrocarbons - A catalyst composition comprising metal phosphate binder and zeolite can be used to enhance olefin yields during hydrocarbon cracking processes. The composition typically further comprises aluminum phosphate, and the metal of the metal phosphate is a metal other than aluminum. Depending on the metal chosen, enhanced propylene and isobutylene yields in fluid catalytic cracking processes can be obtained compared to catalysts that do not contain such metal phosphate binders. The catalyst can also comprise non-zeolitic molecular sieves, thereby making the composition suitable for use in areas outside of catalytic cracking, e.g., purification and adsorbent applications. | 01-14-2010 |
20100252484 | PROCESS FOR PREPARING HIGH ATTRITION RESISTANT INORGANIC COMPOSITIONS AND COMPOSITIONS PREPARED THEREFROM - A process for the production of high attrition resistant inorganic compositions is provided. The formation of highly attrition resistant compositions is accomplished by forming a slurry of inorganic components, a binder, and optionally clay and matrix materials, milling the slurry, and cooling the milled slurry to a temperature below 17° C., preferably below 10° C. The cooled slurry is subjected to spray-drying, and optionally calcining and/or washing, to provide highly attrition resistant inorganic particles. Catalytic cracking catalysts formed by the process are also disclosed. | 10-07-2010 |
