Abstract:
A pre-formation unit, includes: a first vessel comprising a solution of co-catalyst and modifier; a second vessel comprising chromium compound and ligand; wherein the first and second vessel are connected via lines to a mixing unit, wherein each line has a flow control valve; wherein the mixing unit is connected via a line having a flow control valve to an oligomerization reactor; wherein gas inlets are each connected to the first vessel and to the second vessel, and wherein a portion of each of the first vessel, the second vessel, the mixing unit, and the flow control valves are within a temperature controlled enclosure.
Abstract:
The invention relates to a reactor comprising a plasma source and a catalyst comprising a mesoporous support. The invention also relates to a process comprising feeding methane to said reactor in order to obtain one or more of ethene, hydrogen and carbon as well as downstream products derived from ethene thus obtained. The invention relates to a reactor comprising as reactor parts: a. a housing and in said housing; b. a plasma source; and c. a catalyst, wherein said catalyst comprises as catalyst parts: i) a mesoporous support; ii) a metal selected from the group Pd, Ni, Ag or at least two thereof, wherein the metal is carried by said mesoporous support; wherein at least a part of said plasma source is located in said housing upstream of said catalyst.
Abstract:
The present invention relates to a method for oligomerization of ethylene, comprising the steps: a) feeding ethylene, solvent and a catalyst composition comprising catalyst and cocatalyst into a reactor, b) oligomerizing ethylene in the reactor, c) discharging a reactor effluent comprising linear alpha-olefins including I-butene, solvent, unconsumed ethylene dissolved in the reactor effluent, and catalyst composition from the reactor, d) separating ethylene and 1-butene collectively from the remaining reactor effluent, and e) recycling at least a part of the ethylene and the 1-butene separated in step d) into the reactor.
