Patent number: 8742183Abstract: A process has been developed for producing aviation fuel from renewable feedstocks such as plant oils and animal fats and oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide n-paraffins having from about 8 to about 24 carbon atoms. At least some of the n-paraffins are isomerized to improve cold flow properties. At least a portion of the paraffins are selectively cracked to provide paraffins meeting specifications for different aviation fuels such as JP-8.Type: GrantFiled: September 26, 2008Date of Patent: June 3, 2014Assignee: UOP LLCInventors: Michael J. McCall, Terry L. Marker, Richard E. Marinangeli, Joseph A. Kocal

Patent number: 7795483Abstract: The present invention is a process for producing phenyl-alkanes by paraffin adsorptive separation followed by paraffin dehydrogenation and then by alkylation of a phenyl compound by a lightly branched olefin. The adsorptive separation step employs a silicalite adsorbent and, as the desorbent, a C5-C8 linear paraffin, a C5-C8 cycloparaffin, a branched paraffin such as isooctane, or mixtures thereof. The effluent of the alkylation zone comprises paraffins that are recycled to the adsorptive separation step or to the dehydrogenation step. This invention is also a process that that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups that to produce modified alkylbenzene sulfonates. In addition, this invention is the compositions produced by these processes, which can be used as detergents having improved cleaning effectiveness in hard and/or cold water while also having biodegradability comparable to that of linear alkylbenzene sulfonates, as lubricants, and as lubricant additives.Type: GrantFiled: September 9, 2003Date of Patent: September 14, 2010Assignee: UOP LLCInventors: Santi Kulprathipanja, Richard E.

Patent number: 5744679Abstract: Ethylene is effectively oligomerized to linear alpha-olefins using catalyst systems based on transition metal compounds. It has been found that when the reaction is conducted in a polar organic liquid as solvent, incorporation of water into the solvent at levels of 1 to 10 weight percent increases alpha-olefin purity and also influences the Schulz-Flory distribution.Type: GrantFiled: December 27, 1996Date of Patent: April 28, 1998Assignee: UOP LLCInventors: Richard E.

Patent number: 5705712Abstract: A highly integrated process for concurrently producing diisopropyl ether and an isopropyl tertiary alkyl ether has been developed. Optionally, high purity isopropyl alcohol may also be collected as a product. In a first reactor, propylene and water are reacted to form isopropyl alcohol, a portion of which is further reacted to form diisopropyl ether. After removing unreacted propylene, the effluent of the first reactor is separated into an ether rich stream, a water rich stream and an alcohol rich stream. The alcohol rich stream is dried to provide dry isopropyl alcohol. A portion of the dry isopropyl alcohol may be removed and collected as a product. A portion of the dry isopropyl alcohol and isobutylene, isoamylene or a mixture thereof are reacted to form an isopropyl tertiary alkyl ether in a second reactor. Unreacted iso-olefins and inert compounds are then removed from the second reactor effluent.Type: GrantFiled: October 5, 1995Date of Patent: January 6, 1998Assignee: UOPInventors: Stanley J.

The alcohol rich stream and isobutylene, isoamylene or a mixture thereof are reacted to form an isopropyl tertiary alkyl ether in a second reactor. The water present in the alcohol rich stream also reacts with the iso-olefin to form tertiary alcohol. The effluent from the second reactor is water washed to produce an oxygenate product stream and an aqueous alcohol recycle stream. Some tertiary alcohol is recycled to the first reactor where it is reacted with propylene to form additional isopropyl tertiary alkyl ether.Type: GrantFiled: October 5, 1995Date of Patent: November 18, 1997Assignee: UOPInventors: Stanley J. Frey, Robert J. Schmidt, Terry L. Marker, Richard E. Marinangeli

Patent number: 5523508Abstract: Linear alpha-olefin formation via oligomerization of ethylene using transition metal catalysis leads to a Schultz-Flory distribution of oligomers. At modest temperatures formation of heavy oligomers which are waxy solids only partly soluble in the LAO product mix causes reactor plugging and curtailing the time of continuous runs. Recycling a portion of a lighter oligomeric fraction obviates this problem and permits runs uninterrupted by solids formation.Type: GrantFiled: December 29, 1994Date of Patent: June 4, 1996Assignee: UOPInventors: Mark A. Krawczyk, Richard E. Marinangeli, R. Joe Lawson

Patent number: 5491271Abstract: Tetrahedrally charged clays have been found to be active, regenerable catalysts in detergent alkylation, both as delaminated and pillared clays. The pillared saponites and beidellites are especially favored in forming detergent range alkylates using olefins as the alkylating agent to afford products with high monoalkylation selectivity and high linearity. Catalysts can be regenerated by a benzene wash or, after severe deactivation, by a carbon burn.Type: GrantFiled: August 26, 1994Date of Patent: February 13, 1996Assignee: UOPInventors: Richard E. Marinangeli, Jennifer S. Holmgren
