US Patent:

53046943, Apr 19, 1994

Filed:

May 15, 1992

Appl. No.:

7/883638

Inventors:

Ralph M. Dessau - Edison NJ
Quang N. Le - Cherry Hill NJ

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C07C 5333

US Classification:

585662

Abstract:

Catalytic conversion of a C. sub. 2 -C. sub. 5 alkane, e. g. , isobutane and/or isopentane, to isoalkenes, e. g. , isobutene and/or isopentene, respectively, is undertaken in the presence of an aromatic recycle stream which provides the heat of reaction for the conversion which is endothermic, in the absence of hydrogen.

Appl. No.:

7/998807

Inventors:

Ralph M. Dessau - Edison NJ
Quang N. Le - Cherry Hill NJ
Samuel A. Tabak - Voorhees NJ
Robert T. Thomson - Voorhees NJ

Assignee:

Mobil Oil Corporation - Fairfax VA

International Classification:

C07C 502
C07C 522

US Classification:

585253

Abstract:

A method for upgrading an aromatics-containing charge composition boiling in the gasoline boiling range comprises i) contacting the charge composition with a nitrating agent under nitrating conditions to form a product comprising nitrated aromatics; ii) hydrogenating a feed containing the product of i) under conditions sufficient to substantially reduce the nitro group of the nitrated aromatics so as to form a product comprising aromatic amines, water and heavy amines; and iii) removing the water and heavy amines from the product of step ii) to provide a gasoline boiling range product of an octane rating greater than the charge composition.

International Classification:

C07C 264
C07C 268

US Classification:

585455

Abstract:

Long chain alkyl substituted naphthalenes are produced by the alkylation of naphthalene with an olefin or other alkylating agent possessing at least 6 carbon atoms, usually 12 to 20 carbon atoms, in the presence of an alkylation catalyst comprising a zeolite which contains cations having a radius of at least 2. 5. ANG. Cations of this size may be provided by hydrated cations such as hydrated ammonium, sodium or potassium cations or by organoammonium cations such as tetraalkylammonium cations. The zeolite is usually a large pore size ze USY. The presence of the bulky cations in the zeolite increases the selectivity of the catalyst for the production of long chain mono-alkyl substituted naphthalenes in preference to more highly substituted products.

International Classification:

H04L 9/06
H04L 9/32
H04L 29/06

Abstract:

An online identity can be verified based on data from multiple identity sources stored in a blockchain. For example, a request for a token is received from an entity for authenticating an online identity of the entity to an online service. The request can be stored in a blockchain that represents the online identity of the entity by adding a new block to the blockchain. The new block can include data indicating the request for the token. The token can be generated based on the one or more ordered blocks in the blockchain. The token can be transmitted to the entity. The token can be received from the online service. Confirmation of the online identity of the entity can be transmitted to the online service based on receiving the token from the online service.
