20120041243 | INTEGRATION OF A METHANOL-TO-OLEFIN REACTION SYSTEM WITH A HYDROCARBON PYROLYSIS SYSTEM - An integrated MTO synthesis and hydrocarbon pyrolysis system is described in which the MTO system and its complementary olefin cracking reactor are combined with a hydrocarbon pyrolysis reactor in a way that facilitates the flexible production of olefins and other petrochemical products, such as butene-1 and MTBE. | 02-16-2012 |
20120041244 | PRODUCING 1-BUTENE FROM AN OXYGENATE-TO-OLEFIN REACTION SYSTEM - 1-butene is recovered as a purified product from an MTO synthesis and especially from an integrated MTO synthesis and hydrocarbon pyrolysis system in which the MTO system and its complementary olefin cracking reactor are combined with a hydrocarbon pyrolysis reactor in a way that facilitates the flexible production and recovery of olefins and other petrochemical products, particularly butene-1 and MTBE. | 02-16-2012 |
20120322650 | LAYERED CATALYST - One exemplary embodiment can be a layered catalyst for use in a selective hydrogenation of acetylenes and diolefins to olefins. The layered catalyst may include an inner core having an inert material, an outer layer including a metal oxide bonded to the inner core, and a metal deposited on the outer layer. Generally, the metal is an IUPAC Group 8-10 metal and the layered catalyst has an accessibility index of about 3- about 500. | 12-20-2012 |
20120323058 | PROCESS FOR USING LAYERED SPHERE CATALYST - One exemplary embodiment can be a process for selective hydrogenation of acetylenes and diolefins to olefins. The process can include contacting a feedstream having olefins, acetylenes and diolefins with a layered catalyst at reaction conditions. Thus, the process may include creating an output stream with a reduced amount of acetylenes and diolefins. Generally, the layered catalyst has an inner core including an inert material, an outer layer, including a metal oxide, bonded to the inner core, and a metal, which is an International Union of Pure and Applied Chemistry Group 8-10 metal, deposited on the outer layer. Usually, the layered catalyst has an accessibility index of about 3—about 500, a void space index about 0—about 1, or both an accessibility index of about 3—about 500 and a void space index of about 0—about 1. | 12-20-2012 |
