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

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

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

An olefinic composition has a moderate concentration of Type 2 Colefins. The oligomerate composition has hydrocarbon molecules with minimal branching which make excellent diesel and can also be readily cracked to propylene. Consequently, oligomerate product can be sent to the diesel pool or fed or recycled to an FCC unit to increase production of propylene.

Composition of oligomerate

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.

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

Disclosed is the addition of Colefins to oligomerization feed stream has the counterintuitive effect of reducing the production of heavier oligomers over a uni-dimensional, ten-ring pore zeolite. Consequently, Colefins can be added to Colefins in an oligomerization feed stream to produce more gasoline and less distillate.

A hydrogenolysis method for converting glycerol into propylene glycol by directing a glycerol containing feed having a pH of about 10 or more to a reaction section including at least one glycerol conversion catalyst and operating at glycerol conversions conditions to form a reaction product including propylene glycol.

Compositions used for cleansing hair and skin based on the combination of a sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. A route to solve the intrinsic instability of such aqueous compositions in storage has been developed based on the use of sulfosuccinic acid or a salt of sulfosuccinic acid present in an amount of at least about 4% based on the weight of the sulfosuccinate surfactant.

Mild, moisturizing cleansing compositions

Compositions used for cleansing hair and skin based on the combination of an ethoxy sulfosuccinate surfactant and an amphoteric surfactant are described that are very mild but do not compromise in-use properties and economy. It has been found desirable to utilize a mixture of a Mid-Chain alkyl ethoxy sulfosuccinate and a Long-Chain alkyl ethoxy sulfosuccinate wherein the Long-Chain component is present in the composition at a level from about 0.1% to about 6% based on the total weight of the Mid-Chain component.
