Method for producing a base for fuels using an ethylene feedstock performing at least one oligomerisation step in the presence of a homogeneous catalytic system
Producing bases from a C2 ethylene charge, comprises: (a) first step of oligomerization of the charge into at least one hydrocarbon effluent comprising a mixture of 4-30C olefins in the presence of a homogeneous catalyst system comprising at least one metal precursor formed by e.g. titanium; and (b)...

Summary: | Producing bases from a C2 ethylene charge, comprises: (a) first step of oligomerization of the charge into at least one hydrocarbon effluent comprising a mixture of 4-30C olefins in the presence of a homogeneous catalyst system comprising at least one metal precursor formed by e.g. titanium; and (b) second step of oligomerization of at least a portion of the effluent from step (a), into at least one hydrocarbon effluent comprising a mixture of 4-30C olefins in the presence of a homogeneous catalyst system identical or different from that used in step (a). Producing bases from a C2 ethylene charge, comprises: (a) first step of oligomerization of the charge into at least one hydrocarbon effluent comprising a mixture of olefins having a carbon number predominantly 4-30, where the mixture of olefins comprises 10-24C cut having an average linearity of greater than 60%, in the presence of a homogeneous catalyst system comprising at least one metal precursor formed by titanium, zirconium, hafnium, nickel and/or iron; and (b) second step of oligomerization of at least a portion of the effluent from step (a), to at least one hydrocarbon effluent comprising a mixture of 4-30C olefins, where the olefin mixture comprises 10-24C cut having an average linearity of less than 50%, in the presence of a homogeneous catalyst system identical or different from that used in step (a). |
