Abstract: Un sistema proporciona un gas que contiene oxígeno y una corriente de reactivo gaseoso a un reactor de lecho fluidizado usando un aspersor para introducir el gas que contiene oxígeno dentro de la corriente de gas reactivo. Una linea de alimentacion acopla el aspersor al lecho fluidizado del reactor e introduce la corriente de gas reactivo y el gas que contiene oxigeno introducido en contacto con el lecho fluidizado. Un controlador controla y mantiene la cantidad de gas que contiene oxigeno y el reactivo gaseoso sobre un limite de flamabilidad superior, preferiblemente con un margen de seguridad de por lo mneos 10%.

Abstract: This invention is directed towards an improved process for the selective gas phase oxidation of a organic reactant using a metal oxide redox catalyst, wherein the organic reactant and air feeds are at a substantially continuous level, the improvement comprising adding a fluctuating flow of oxygen at alternating relatively high and relatively low levels. The invention also teaches means by which a gas may be provided to a reaction process on a fluctuating basis.
