Oligomerizing Cand Colefins over a SPA catalyst provides an oligomerate product stream comprising C+ olefins that meets a gasoline T-90 specification of 380&#xb0; F. The oligomerate product stream can be taken to the gasoline pool without further upgrading.

Process for oligomerizing gasoline without further upgrading

Radiant fired heaters used with reactors are described. The apparatus includes at least two sets of radiant fired heaters, the first set being at a second height less than the first height. Each set of radiant fired heaters comprises at least one radiant fired heater. Each radiant fired heater has at least one process coil disposed within the heater, burners, and a flue gas outlet. There is at least one inlet manifold having an inlet and multiple outlets, with each outlet of the inlet manifold in fluid communication with one process coil inlet. There is an outlet manifold having multiple inlets and an outlet, with the multiple inlets in fluid communication with the process coil outlets. A method of selecting a reforming apparatus arrangement is also described.

Disclosed is a process and apparatus for switching oligomerization feed between a first oligomerization zone that includes a uni-dimensional small pore zeolite to make more diesel and a second oligomerization zone that includes SPA catalyst for making more gasoline. The diesel can be recycled to make more propylene. The process and apparatus will provide refiners with flexibility to produce the most valuable product commensurate with fluctuating market conditions.

Process for oligomerizing light olefins

Distillate cracks to propylene more readily than VGO. Additionally, less branched hydrocarbons crack to propylene more readily than more branched hydrocarbons. Oligomerization to diesel range oligomers followed by catalytic cracking with less branched oligomers can provide more propylene.

Process for fluid catalytic cracking oligomerate

An inexpensive heat exchanger is disclosed, wherein the heat exchanger is made up of a plurality of plates and each plate has at least one channel defined in the plate. The plates are stacked and bonded together to form a block having conduits for carrying at least one fluid and where the exchanger includes an expansion device enclosed within the unit. The plates include construction to thermally insulate the sections of the heat exchanger to control the heat flow within the heat exchanger.

A first oligomerization stream is oligomerized over a first catalyst in a first oligomerization reactor zone to make oligomerate. An oligomerate stream is separated to provide a heavy oligomerate boiling in the diesel range and a second oligomerization feed stream. The latter is fed to a second oligomerization reactor zone with a second different catalyst to produce the heavy oligomerate.

Process for oligomerization of gasoline to make diesel

A process sends at least a portion of an oligomerization feed to a first oligomerization reactor zone that includes a zeolite or a SPA catalyst and another portion of the same feed to a second oligomerization reactor zone that includes an amorphous silica alumina catalyst. The first oligomerization reactor zone makes aliphatic olefins that can be cracked to propylene and the second oligomerization reactor zone makes cyclic molecules that can be converted to aromatics in an FCC unit.

Process for oligomerizing and cracking to make propylene and aromatics

Recycle of a stream comprising Coligomers to an oligomerization zone to be oligomerized with Colefins can produce diesel range oligomers. A diesel stream can be separated from a gasoline stream which can be recycled to the oligomerization zone.

Process for making diesel by oligomerization of gasoline

A process provides oligomerization feed stream comprising Chydrocarbons and olefins along with Colefins to an oligomerization zone. The oligomerization feed stream may be obtained from cracked FCC products. Unreacted Chydrocarbons can be recycled to the oligomerization zone to maintain the liquid phase therein.

Process for oligomerizing light olefins including pentenes

A process for reforming hydrocarbons is presented. The process involves applying process controls over the reaction temperatures to preferentially convert a portion of the hydrocarbon stream to generate an intermediate stream, which will further react with reduced endothermicity. The intermediate stream is then processed at a higher temperature, where a second reforming reactor is operated under substantially isothermal conditions.

Disclosed is that by oligomerizing Colefins over a uni-dimensional 10-ring pore structured zeolite catalyst, at least 70 wt % oligomers having at least 9 carbons can be produced in a single pass.

Process for making diesel by oligomerization

Provided is a process for producing aromatics including the steps of preparing a Chydrocarbon stream, feeding a naphtha stream and the Chydrocarbon stream to a reforming unit, and reforming the naphtha stream and the Chydrocarbon stream to yield aromatics. The process combines a co-feed containing Chydrocarbons, an alkali/alkaline earth metal-containing reforming catalyst, and a high temperature operating regime to achieve significant improvements in a reforming process for the production of xylenes and other aromatics.

Process for xylenes production

A process for transalkylating a coal tar stream is described. A coal tar stream is provided, and is fractionated to provide at least one hydrocarbon stream having polycyclic aromatics. The hydrocarbon stream is hydrotreated in a hydrotreating zone, and then hydrocracked in a hydrocracking zone. A light aromatics stream is added to the hydrocracking zone. The light aromatics stream comprises one or more light aromatics having a ratio of methyl/aromatic available position that is lower than a ratio of methyl/aromatic available position for the hydrotreated stream. The hydrocracked stream is transalkylated in the hydrocracking zone.
