    摘要： A process is proposed for continuously operating a plant for preparing acetylene from hydrocarbons by partial oxidation, cleavage in an arc or pyrolysis of hydrocarbons to obtain a reaction gas mixture which is conducted through one or more compressors, the pressure of the reaction gas mixture on the suction side of the compressor being controlled within a predefined range by means of a conventional controller, which comprises additionally using a higher-level model-supported predictive controller which reacts to abrupt changes in the mass flow rate of the reaction gas mixture.
