Process for producing acrylonitrile acrylonitrile or Mythakrylwnytryl methacrylonitile of propane or propane iosbutane isobutane by oxidative stress in the presence of ammonia ammoxidation

摘要

Abstract: the invention relates to a process for producing acrylonitrile or acrylonitrile Mythakrylwnytryl methacrylonitrile of propane or propane iosbutane isobutane by oxidative stress in the presence of ammonia am Moxidation, at a temperature ranging from $. 500 in the reactor Mtmyh layer contains the compound stimulated catalyst is pre heated to a temperature not less than 300 mm and less than a temperature of the oxidation reaction at The presence of ammonia ammoxidation, jRide (composite material carrier (catalyst) are stimulated by Aksydy oxide composite of Almwlbydywm molybdenum vanadium, niobium, vanadium, niobium component and at least one selected from the Altylyrywm tellurium and Alantymwn antimony, preceded by an oxidative stress in the presence of ammonia ammoxidation Llbrwban or propane iosbutane isobutane) process to raise the temperature to a certain limit.The temperature of the catalyst is raised in the reactor, while supplying the reactor, the class Almtmyh molecular Ghazqabl oxygen with gas containing molecular oxygen for combustion by means of interaction. M Molecular oxygen P molecular oxygen in the presence of said composite catalyst, until the temperature of the composite oxidation catalyst to the reaction temperature in the presence of ammonia ammoxidation.The object of this invention to raise the temperature of the composite catalyst can be effectively without damage of the catalyst by raising temperature, it allows the incentive to is working at full capacity.
