US Patent:
5256810, Oct 26, 1993
Filed:
Oct 14, 1992
Appl. No.:
7/960653
Inventors:
Steven J. Rowe - Medina OH
John T. Shultz - Medina OH
Robert J. Mack - Elida OH

Assignee:
The Standard Oil Company - Cleveland OH
International Classification:
C07C25326
US Classification:
558320
Abstract:
An improved process for substantially eliminating, preferably completely eliminating of nitride formation on feed conduits for fluid bed catalyst reactors used in the manufacture of unsaturated nitriles from corresponding olefins, NH. sub. 3 and oxygen comprising maintaining the temperature of the ammonia inside the conduit below its dissociation temperature and/or maintaining the temperature of the inside surface of the conduit below the temperature at which any monoatomic nitrogen can react with the conduit to form a nitride.
Maintaining Vpo Catalyst Performance By Aluminizing Reactor Internals In Oxidation Of Butane To Maleic Anhydride
US Patent:
5326886, Jul 5, 1994
Filed:
Dec 9, 1991
Appl. No.:
7/803947
Inventors:
John T. Shultz - Medina OH
Assignee:
The Standard Oil Company - Cleveland OH
International Classification:
C07D30760
US Classification:
549259
Abstract:
Catalysts comprising a compound of vanadium, phosphorus and oxygen which are employed in the oxidation of n-butane to maleic anhydride are protected from contamination caused by side reactions which occur between the catalyst and steel process equipment by covering the process equipment surfaces which contact the catalyst at elevated temperatures with a coating comprising aluminum oxide.
