A process is disclosed for alkylating an isoparaffin with an olefin comprising the steps of: (a) reacting an isoparaffin having from 4 to 8 carbon atoms with an olefin having from 2 to 12 carbon atoms in a first alkylation reaction stage at temperature from about -40.degree. C. to about 500.degree. C. and overall isoparaffin:olefin feed weight ratio of from about 1:1 to about 250:1 with a solid alkylation catalyst comprising a synthetic porous crystalline material characterized by an X-ray diffraction pattern including values substantially as set forth in Table I of the specification and having a composition comprising the molar relationship

Isoparaffin/olefin alkylation

There are provided a catalyst, a method for making this catalyst, and a process for using this catalyst in the alkylation of an isoparaffin with an olefin to provide an alkylate. The catalyst may be made from an as-synthesized material which, upon calcination, is capable of generating zeolites designated MCM-22. The as-synthesized material is then combined with a binder material, such as alumina, by an extrusion process. The uncalcined bound material may then be ammonium exchanged, followed by a calcination treatment. The as-synthesized material may also be swollen with a suitable swelling agent, such as a cetyltrimethylammonium compound, prior to the binding process.

Catalyst and process for isoparaffin-olefin alkylation

This invention provides a process for upgrading hydrocarbon feedstock comprising the steps of:

Process for the production of alkylate gasoline from FCC light aliphatics

Process for alkylating an olefin with an isoparaffin comprising contacting an olefin-containing feed with an isoparaffin-containing feed with a crystalline microporous material under alkylation conversion conditions including temperature at least equal to the critical temperature of the principal component of the feed and pressure at least equal to the critical pressure of the principal component of the feed.

Solid catalyzed supercritical isoparaffin-olefin alkylation process

The alkylation of isoparaffin with olefin to provide alkylate is carried out in the presence of, as catalyst, MCM-36.

Isoparaffin-olefin alkylation process with zeolite MCM-36

The invention provides an isoparaffin: olefin alkylation process comprising contacting isoparaffin and olefin with a synthetic porous crystalline material which is characterized, in its uncalcined form, by an X-ray diffraction pattern including values substantially as set forth in Table I of the specification and having a composition comprising the molar relationship

Isoparaffin:olefin alkylation in the presence of synthetic porous MCM-49

The present invention provides a process for alkylating an isoparaffin with an olefin comprising contacting an isoparaffin having from 4 to 8 carbon atoms with an olefin having from 2 to 12 carbon atoms in an alkylation reaction zone at temperature from about -20.degree. C. to about 200.degree. C. in the presence of a Bronsted acid and an inorganic, porous crystalline phase material having, after calcination, a d-spacing greater than about 18 Angstrom Units and having a benzene adsorption capacity of greater than 15 grams benzene per 100 grams of said material at 50 torr and 25.degree. C., wherein the molar ratio of said isoparaffin to said olefin is from about 1:1 to about 250:1 to evolve a product stream containing C.sub.5 + alkylate. In a preferred embodiment, the alkylation catalyst complex comprises a Bronsted acid and an inorganic, porous crystalline phase material having, after calcination, a hexagonal arrangement of uniformly-sized pores having diameters of at least about 13 Angstrom Units and exhibiting a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units.

Light olefins are converted to isoalkene-rich hydrocarbon products, e.g., isobutene and isoamylenes with zeolite MCM-22 catalyst.
