| titleOfInvention | Oligomerization method in cascade of stirred gas-liquid reactor with stepwise injection of ethylene |
| abstract | The present invention is carried out in a cascade of N gas/liquid reactors connected in series (N is at least 2) at a pressure between 0.1 MPa and 10 MPa, at a temperature between 30° C. and 200° C., oligomerization of ethylene. Comprising: introducing a catalytic oligomerization system into at least a first reactor of a cascade; Contacting the catalyst system and the optional solvent with the ethylene by introducing ethylene into at least the lower part of the reaction chamber of the first reactor of the cascade; For each reactor n, recovering the liquid fraction at the bottom of the reaction chamber of reactor n, wherein the liquid fraction is separated into two streams, the first stream being the first of the liquid fraction conveyed to the heat exchanger for cooling. 1, recovering the liquid fraction, corresponding to the "main" portion, the second stream corresponding to the second portion of the liquid fraction constituting the liquid feedstock of the next reactor n+1 in the cascade; Introducing the second portion of the liquid recovered from the reactor n toward the reaction chamber of the next reactor n+1 in a flow direction; Cooling the first portion of the liquid fraction recovered from reactor n in step c) by passing the first portion of the liquid fraction to a heat exchanger to obtain a cooled liquid fraction; Introducing the liquid fraction cooled in step e) to the top of the reaction chamber of the reactor n, wherein steps a) to f) are each reactor n of the cascade, unless otherwise indicated, where n is 1 and N Between). The invention also relates to a device of N stirred gas/liquid reactors in a cascade capable of carrying out an oligomerization process. |
