Abstract
In the recovery of acrylonitrile from the gross reaction product produced during the commercial ammoxidation of propylene to produce acrylonitrile, an ammoxidation waste gas containing at least 65% nitrogen, carbon dioxide, carbon monoxide and a small amount of unreacted propylene is produced. In accordance with the invention, this ammoxidation waste gas is passed through a catalytic converter containing an oxidation or ammoxidation catalyst to convert the unreacted propylene into valuable product.
