Abstract
The invention concerns a process and apparatus for manufacturing methyl tert-butyl ether (MTBE) by reacting methanol with an isobutene-containing hydrocarbon mixture. This process is characterized by the steps of: PA1 introducing the reactants into a reaction-distillation zone containing at least two superposed and non-contiguous fixed beds (2a, 2b) of catalyst of the sulfonated resin type, wherein passageways are provided for a vapor phase, at least one distillation tray (4a), at least one liquid redistribution tray (5), PA1 maintaining distillation conditions in the zone so as to have a descending liquid phase and an ascending vapor phase, PA1 maintaining a continuous liquid phase in the lower part of the beds, PA1 discharging a vapor phase containing a high proportion of unconverted hydrocarbons from the top (8) of the zone, and PA1 withdrawing a liquid phase of high MTBE content from the bottom (10) of the zone.
