PRODUCTION OF MIDDLE DISTILLATE HYDROCARBON COMPOSITION |
摘要 |
<p>A process for the preparation of a middle distillate hydrocarbon composition from ethylene, wherein said process comprises the following steps: (a) feeding an ethylene composition in to an oligomerisation reaction zone containing a supported nickel oligomerisation catalyst to form an oligomerisation product A, wherein the oligomerisation reaction is operated at a temperature in the range of from 30 to 300 °C and a pressure of at least 10 bara; (b) separating a light products stream B, a middle distillate product stream C and a heavy products stream D from oligomerisation product A, wherein the light product stream B comprises the fraction of oligomerisation product A which boils in the C2-C8 mono-olefin boiling range and the middle distillate product stream C comprises a fraction of oligomerisation product A which boils above the boiling range of the light product stream B and below the boiling range of the heavy products stream D, and wherein the heavy product stream D comprises the fraction of oligomerisation product A which boils above the C22 mono-olefin boiling range; (c) recycling at least a portion of the light products stream B to the oligomerisation reaction zone of step (a) of the process; (d) cracking the heavy product stream D in a cracking reactor to produce a cracked product stream E; (e) separating a middle distillate product F from the cracked product stream E; and (f) hydrogenating the middle distillate product stream C, wherein the middle distillate hydrocarbon composition comprises at least a portion of the hydrogenated middle distillate product stream C and at least a portion of the middle distillate product F.</p> |
