  • Patent number: 11180433
    Abstract: The invention relates to a process and a plant for producing methanol from an input gas including carbon monoxide and hydrogen using a pre-reactor stage and a main reactor stage. Input gas produced at and under elevated pressure is initially introduced into a pre-reactor stage for catalytic conversion into a first methanol-containing product stream. After separation of methanol from the first methanol-containing product stream and discharging from the pre-reactor stage a remaining gas stream is introduced into a main reactor stage as a residual gas stream after compression to reaction pressure for catalytic conversion into a second methanol-containing product stream, After separation from the second methanol-containing product stream methanol is discharged from the main reactor stage. Using an input gas having a carbon monoxide content of 25% to 36% by volume results in large savings in respect of the compressor output required for the production process.

  • Patent number: 10913698
    Abstract: A process for conducting exothermic equilibrium reactions, especially for the performance of methanol synthesis by heterogeneously catalysed conversion of synthesis gas, is proposed, which enables readjustment and hence optimization of the reaction conditions along the longitudinal coordinate of the reactor. For this purpose, in the process according to the invention, a reactor is used which is divided into a multitude of series-connected reaction cells, each of which comprises a preheating zone, a cooled reaction zone, one or more cooling zones and a deposition zone for condensable reaction products. In this way, the reaction conditions are adjustable to the respective, local composition of the reaction mixture and variable over the reactor length.

  • Patent number: 10737230
    Abstract: The invention relates to a reactor for the catalytic production of methanol, in which at least two catalyst layers are arranged. The first catalyst layer is arranged upstream and the second catalyst layer is arranged downstream. The activity of the first catalyst layer is higher than the activity of the second catalyst layer.
