Patent number: 10774017Abstract: The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. Isopentane and smaller hydrocarbons are separated to form a first fraction while n-pentane and larger components of the feed stock form a second fraction. Each fraction is then catalytically-activated in a separate reaction zone with a separate catalyst, where the conditions maintained in each zone maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first fraction is activated at a lower temperature than the second fraction. The process provides increased yields of upgraded hydrocarbon products that possess the characteristics of a liquid transportation fuel or a blend component thereof.Type: GrantFiled: March 26, 2019Date of Patent: September 15, 2020Assignee: PHILLIPS 66 COMPANYInventors: Anthony O. Baldridge, Neal D. McDaniel, James A. Suttil, Soumen Kundu, Jianhua Yao, Bruce B. Randolph, Maziar Sardashti, Steven E. Lusk, Robert M. Walston, Jr.

Publication number: 20200109341Abstract: The present disclosure relates to systems operable to catalytically convert a hydrocarbon feed stream predominantly comprising both isopentane and n-pentane to yield upgraded hydrocarbon products that are suitable for use either as a blend component of liquid transportation fuels or as an intermediate in the production of other value-added chemicals. The hydrocarbon feed stream is isomerized in a first reaction zone to convert at least a portion of the n-pentane to isopentane, followed by catalytic-activation of the isomerization effluent in a second reaction zone with an activation catalyst to produce an activation effluent. The process increases the conversion of the hydrocarbon feed stream to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. Certain embodiments provide for further upgrading of at least a portion of the activation effluent by either oligomerization or alkylation.Type: ApplicationFiled: October 4, 2019Publication date: April 9, 2020Applicant: PHILLIPS 66 COMPANYInventors: Anthony O. Baldridge, Neal D. McDaniel, James A. Suttil, Edward C. Weintrob, Jianhua Yao, Bruce B. Randolph, Maziar Sardashti, Robert M. Walston, Steven E. Lusk

Patent number: 10487277Abstract: Systems operable to produce liquid transportation fuels by converting a hydrocarbon feed stream that comprises both isopentane and n-pentane. The system separates the hydrocarbon feed stream to form a first fraction comprising isopentane and smaller hydrocarbons, and a second fraction comprising n-pentane and larger components of the hydrocarbon feeds stream. Each fraction is then catalytically-activated in a separate activation reactor containing a separate activation catalyst, where the conditions maintained in each reactor are selected to maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. Optionally, the first activation reactor is maintained at a lower temperature than the second activation reactor.Type: GrantFiled: March 26, 2019Date of Patent: November 26, 2019Assignee: PHILLIPS 66 COMPANYInventors: Anthony O.
