Abstract:
A tubular reactor that produces maleic anhydride from a gas mixture containing n-butane and oxygen includes a first reaction zone including an inlet for the gas mixture and a second reaction zone including an outlet for a reaction gas mixture, a plurality of tubes extending in an axial direction through the first and second reaction zones, a temperature control system, configured for controlling a reaction temperature in each of the reaction zones independently, includes a heat transfer system for each of the reaction zones configured for controlling the temperature of a liquid coolant flowing through one of the reaction zones, and a circulation pumping system configured for controlling flow conditions of the liquid coolant flowing through the reactor and one of the heat transfer systems, and a preheating arrangement configured for preheating the gas mixture such that the gas mixture enters the first reaction zone at a predefined inlet temperature.

Claim (Index 5):
The tubular reactor of  claim 1 , wherein the temperature control system comprises a circulation pumping system for each of the reaction zones configured for controlling the flow conditions of the liquid coolant flowing through one of the reaction zones and one of the heat transfer systems independently from the other one of the reaction zones and the other one of the heat transfer systems.
