Production of heavier hydrocarbons from light olefins in multistage catalytic reactors. |
摘要 |
<p>A multi-stage catalytic olefin upgrading technique for converting lower olefinic feedstock to heavier liquid hydrocarbon product. The invention comprises converting in a fluid bed continuous primary stage reaction zone with shape selective medium pore zeolite oligomerization catalyst particles at least a portion of the lower olefinic components to intermediate olefinic hydrocarbons containing olefinic and aromatic components; cooling primary stage reaction effluent to condense at least a portion of the intermediate hydrocarbons; feeding a second olefinic stream to a serially arranged multi-reactor secondary stage for upgrading lower olefins; quenching partially upgraded secondary stage olefins with primary stage liquid; and further contacting the quenched mixture including aromatics from the primary stage with shape selective medium pore zeolite oligomerization catalyst in a high pressure fixed bed secondary stage distillate mode catalytic reactor at elevated temperature and high pressure to provide a heavier hydrocarbon effluent stream comprising distillate hydrocarbons.</p> |
