Abstract: 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.

Abstract: 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.
