Patent number: 10315131Abstract: A method for preparing a crude oil solution for analysis, including adding water to a porous adsorbent to obtain a supported water substrate, having a plurality of water monolayers disposed on the porous adsorbent. The method further includes exposing the crude oil solution to the supported water substrate for a period of time; separating the supported water substrate from the crude oil solution; washing the supported water substrate with a water immiscible solvent to remove at least one hydrocarbon; displacing water from the plurality of water monolayers and the at least one interfacially active compound from the porous adsorbent with an alcohol and a co-solvent to obtain a displaced phase. The displaced phase can include the water, the at least one interfacially active compound, the alcohol, and the co-solvent. Finally, the method can include drying the displaced phase to isolate the at least one interfacially active compound.Type: GrantFiled: October 22, 2013Date of Patent: June 11, 2019Assignee: FLORIDA STATE UNIVERSITY RESEARCH FOUNDATION, INC.Inventors: Jacqueline M. Jarvis, Ryan P. Rodgers, Winston K. Robbins

Determination of the distribution of reactive and non-reactive sulfur in petroleum and its fractions
Patent number: 10048244Abstract: A method to determine the distribution of non-reactive sulfur compounds and reactive sulfur compounds in petroleum samples by separating non-reactive sulfur compounds from reactive sulfur compounds in a petroleum composition includes the step of contacting the petroleum composition with a Ag-containing cation exchange media. The petroleum composition and the Ag-containing cation exchange media are contacted with a non-reactive sulfur compound solvent capable of eluting the non-reactive sulfur compounds in the presence of the Ag-containing cation exchange media and incapable of eluting the reactive sulfur compounds in the presence of the Ag-containing cation exchange media at the conditions of the exchange. The non-reactive sulfur compounds are eluted from the media with the non-reactive sulfur compound solvent to provide a first fraction. The amount of non-reactive sulfur compounds in the first fraction is then determined.Type: GrantFiled: March 13, 2014Date of Patent: August 14, 2018Assignee: FLORIDA STATE UNIVERSITY RESEARCH FOUNDATION, INC.Inventors: Ryan P.
