Abstract: A process for oligomerizing olefins to distillate fuels which oligomerizes a recycle olefin stream with a charge olefin stream in a first-stage oligomerization reactor. The first-stage oligomerate is oligomerized in a second-stage oligomerzation reactor to provide a second-stage oligomerate stream. A recycle olefin stream is taken from said second-stage oligomerate stream.

Abstract: A process for oligomerizing olefins to distillate fuels which oligomerizes a recycle olefin stream with charge olefin streams in a first-stage oligomerization reactor. The first-stage oligomerate is oligomerized in a second-stage oligomerization reactor to provide a second-stage oligomerate stream. A recycle olefin stream is taken from said second-stage oligomerate stream. A dealkanizer column can be used to remove light alkanes that would be inert and accumulate in a recycle loop. The second-stage oligomer product stream is hydrogenated to produce fuels.

Abstract: A regenerator vessel for adsorbing halogen-containing material from a regenerator vent gas stream has a plurality of catalyst nozzles disposed at a top portion of the regenerator vessel. A first gas outlet is associated with a chlorination zone, and a second gas outlet associated with a combustion zone. A drying zone is in fluid communication with an air heater and the drying zone located in a bottom portion of the regenerator vessel. The first gas outlet is configured to withdraw a first gas stream from the chlorination zone and the second gas outlet is configured to withdraw a second gas stream from the combustion zone. The top portion of the regenerator vessel has an adsorption zone having a vent gas inlet port, a vent gas outlet port, and a portion of an annular catalyst bed.

Abstract: A process for the production of a liquid fuel from carbon oxides and hydrogen is disclosed. The process comprises reacting a mixture of carbon oxides and hydrogen to produce methanol. The methanol is contacted with an MTO catalyst to produce an olefin stream. The olefin stream is oligomerized with an oligomerization catalyst to produce an oligomerized olefin stream which is then hydrogenated to produce the liquid fuel streams jet fuel, diesel, and naphtha. At each stage, waste streams are produced. A syngas stream is produced comprising carbon oxides and hydrogen by (1) steam reforming, autothermal reforming, or dry reforming; or (2) partial oxidization.

Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which utilizes a solid acid catalyst for ethylene oligomerization in a first stage and a metal catalyst for further oligomerization in a second stage. Distillate fuels can be produced from the process. Oligomerized olefins may be recycled to the first stage oligomerization reaction to ensure sufficient oligomerization of smaller olefins.

IPC: C10G50/00
Abstract: A process for oligomerizing an olefin stream comprising charging a light olefin vapor stream comprising ethylene to a first oligomerization reactor containing a first oligomerization catalyst to produce a first oligomerized stream. A heavy olefin liquid stream comprising C3-C8 olefin liquids stream is charged to a second oligomerization reactor containing a second oligomerization catalyst to produce a second oligomerized stream. The two oligomerized streams can be processed to recover fuel streams together.

Abstract: A process for oligomerizing olefin streams comprising sending olefin streams comprising a C2− olefin vapor stream and a C3+ olefin liquids stream to a first stage oligomerization reactor containing a solid acid oligomerization catalyst to produce a first stage oligomerized stream; oligomerizing said first-stage oligomerization stream in a second stage oligomerization reactor containing a metal catalyst to provide a second stage oligomerized stream.
