Title: Ammoxidation of alkanes and alkenes
Inventor: LI YUEJIN
IPC: B01J29/072
Filed: 1996-09-04
Abstract: 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 VIIB and VIII of the Periodic Table.  The silica-alumina can be amorphous but is preferably crystalline zeolite.  Preferred zeolites are ZSM-5, beta and NU-87.  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. Ammoxidation of alkanes produce alkenes as a byproduct which can be recycled to the reaction to increase nitrile yield.

Title: Heat exchanger for use in high temperature applications
Inventor: NATARAJAN CUDDALORE PADMANABAN
IPC: F28D7/16
Filed: 1996-11-27
Abstract: A heat exchanger achieves a more uniform internal temperature gradient within its scctions during normal operation as well as subsequent to an unexpected power shutdown. Internal fouling of tubes containing the process gas and entrained solids is reduced. An external shell is utilized which is insulated on its inner surface and optionally provided with cooling medium flowing within the shell wall.  A double bottom tube sheet enclosing a secondary cooling medium chamber is also provided.  The top of the process gas tube is preferably enclosed within a shielded chamber to facilitate a thermal gradient proximate thereto.  A ferrule is similarly affixed to the bottom of the process gas tube at the point where it passes through the double bottom tube sheet.  Cooling medium flow is diverted and passed directly into the cooling chamber of the double bottom tube sheet.  Cooling medium from the double bottom tube sheet is then vented to the top of the heat exchanger to a point adjacent the top tube sheet.  A secondary blower for propulsion of the cooling medium is provided in line with the normal flow of cooling medium from the primary blower.  Under unexpected shutdown conditions, the primary blower operation is discontinued and the secondary blower continues its propulsion of cooling medium through the double bottom tube sheet and the main cooling medium chamber.
