Patent number: 7427388Abstract: A process for prereforming natural gas containing higher hydrocarbons and methane, includes providing a reactor having a nickel catalyst; providing steam, hydrogen, and natural gas containing higher hydrocarbons and methane to the reactor; adding an oxidant to the feedstock, wherein the oxidant provides oxygen in an amount less than the amount required to partially oxidize all higher hydrocarbons to a mixture of carbon monoxide and hydrogen; reacting the oxidant with higher hydrocarbons; and forming a gaseous mixture containing methane, carbon monoxide, carbon dioxide, steam and hydrogen substantially free of higher hydrocarbons and oxygen. The gaseous mixture can be reformed. An apparatus for performing the process includes a reactor; a feedstock source containing steam, hydrogen, and natural gas comprising higher hydrocarbons and methane; an oxidant source; valves and pipes connecting the natural gas source, the oxidant source and the reactor; and a nickel-containing catalyst within the reactor.Type: GrantFiled: March 19, 2004Date of Patent: September 23, 2008Assignee: Air Products and Chemicals, Inc.Inventors: Diwakar Garg, Shankar Nataraj, John Nelson Armor, John Michael Repasky

Patent number: 5756802Abstract: Acetonitrile is produced directly from alkanes or alkenes by ammoxidation over a catalyst which is a silica-alumina exchanged with a metal of Period 4, Groups VIIA and VIII of the Periodic Table. The silica-alumina can be amorphous but is preferably crystalline zeolite. Preferred zeolite include ZSM-5, beta, NU-87 and USY. Cobalt is the favored metal for exchange. Particularly good results are obtained when the zeolite has been modified with a surface coating of silicon oxides prior to the metal exchange or modified with a boron or phosphorous containing compound followed by calcination. Ammoxidation of alkanes produce alkenes as a byproduct which can be recycled to the reaction to increase acetonitrile yield.Type: GrantFiled: November 25, 1996Date of Patent: May 26, 1998Assignee: Air Products and Chemicals, Inc.Inventors: Yuejin Li, John Nelson Armor, Peter Charles Hohl
