Aromatics Alkylation With Cracked Recycled Plastics

View page
US Patent:
57057249, Jan 6, 1998
Filed:
Oct 26, 1995
Appl. No.:
8/548850
Inventors:
Nick A. Collins - Medford NJ
Larry A. Green - Mickleton NJ
Anagha A. Gupte - Marlton NJ
David O. Marler - Deptford NJ
William J. Tracy - Sewell NJ
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
C07C 266
US Classification:
585446
Abstract:
A process is disclosed for the production of alkylaromatic compounds employing olefinic liquid from thermally or catalytically cracked plastics as alkylating agent. The process comprises contacting a feedstream comprising alkylatable aromatics and the olefinic liquid with acidic alkylation catalyst under alkylation conditions in an alkylation zone; and recovering an effluent stream comprising alkylaromatic compounds. The alkylation can be performed with the product of plastics pyrolysis or with non-degraded plastic feedstock in-situ with thermal/catalytic degradation of the plastic.

Selective Re-Extraction Of Lube Extracts To Reduce Mutagenicity Index

View page
US Patent:
61465208, Nov 14, 2000
Filed:
Apr 2, 1997
Appl. No.:
8/829882
Inventors:
Anagha Avinash Gupte - Moorestown NJ
David O. Marler - Deptford NJ
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
C10G 2112
US Classification:
208322
Abstract:
A process for reducing the Mutagenicity Index and/or the PCA content of a lubricating oil extract by re-extracting a lubricating oil extract with a second extraction solvent, different from the first extraction solvent, to form a secondary raffinate and a secondary extract mix; separating the secondary raffinate from the secondary extract mix; and separating the secondary raffinate and the secondary extract from said second extraction solvent.

Addition Of Ethers Or Aldehydes To Furfural For Aromatic Extractions

8/704058
Inventors:
Anagha Avinash Gupte - Moorestown NJ
Michael E. Landis - Sewell NJ
David Owen Marler - Deptford NJ
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
C10G 2102
US Classification:
208323
Abstract:
A process to improve the performance of furfural for aromatics extraction from gas oils and lube distillates by the addition of ethers and/or aldehydes, preferably having a dielectric constant less than about 40 @ 25. degree. C.

Separation Of Sulfolane From Conjunct Polymeric Byproducts

View page
US Patent:
52625796, Nov 16, 1993
Filed:
Dec 17, 1992
Appl. No.:
7/991918
Inventors:
Jonathan E. Child - Sewell NJ
Anagha A. Gupte - Marlton NJ
Tomas R. Melli - Sewell NJ
Sergei Yurchak - Media PA
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
C07C 262
C07C 710
US Classification:
585802
Abstract:
The present invention provides a method for separating sulfolane from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid comprising the sequential steps of: (a) removing HF from said mixture to provide an intermediate stream containing less than about 30 weight percent HF; (b) contacting said intermediate stream with water; (c) contacting said intermediate stream with an aliphatic hydrocarbon co-solvent having from about 3 to about 20 carbon atoms concurrently with said water-contacting step (b); (d) recovering an extract stream enriched in sulfolane and hydrofluoric acid; and (e) recovering a raffinate stream enriched in conjunct polymers.

Method For Separating Conjunct Polymeric Byproducts From Mixture Containing Hydrofluoric Acid And A Sulfone

View page
US Patent:
52646521, Nov 23, 1993
Filed:
Dec 17, 1992
Appl. No.:
7/991921
Inventors:
Jonathan E. Child - Sewell NJ
Edward H. Edelson - Cherry Hills NJ
Anagha A. Gupte - Marlton NJ
Rafi Jalkian - Mantua NJ
Tomas R. Melli - Sewell NJ
Sergei Yurchak - Media PA
Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
C07C 262
C07C 710
US Classification:
585802
Abstract:
The present invention provides a method for separating conjunct polymers which are formed as byproducts of acid catalyzed isoparaffin-olefin alkylation and sulfolane from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid comprising the sequential steps of: (a) separating hydrofluoric acid from said mixture to provide an intermediate stream containing less than about 30 percent hydrofluoric acid by weight; (b) gravitationally separating said intermediate stream into a more dense sulfolane-enriched stream and a less dense conjunct polymer-enriched stream; (c) distilling said more dense sulfolane-enriched stream of step (b) to provide an overhead stream containing a higher sulfolane concentration than said more dense sulfolane-enriched stream of step (b) and a bottom stream enriched in conjunct polymers.

Assignee:
Mobil Oil Corporation - Fairfax VA
International Classification:
C07C 268
C07C 710
US Classification:
585802
Abstract:
The present invention provides a method for separating conjunct polymers which are formed as byproducts of acid catalyzed isoparaffin-olefin alkylation and sulfolane from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid comprising the sequential steps of: (a) separating hydrofluoric acid from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid to provide a first intermediate stream containing less than about 30 percent hydrofluoric acid by weight; (b) mixing said intermediate stream with a nonpolar extraction solvent to provide a second intermediate stream; and (c) gravitationally separating said intermediate stream into a less dense extract stream enriched in conjunct polymers and a more dense liquid stream enriched in sulfolane.
