Patent number: 11390820Abstract: Naphtha boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. The resulting naphtha boiling range fractions can have a high naphthenes to aromatics weight ratio, a low but substantial content of aromatics, and a low sulfur content. In some aspects, the fractions can be used as fuels and/or fuel blending products after fractionation with minimal further refinery processing. In other aspects, the amount of additional refinery processing, such as hydrotreatment, catalytic reforming and/or isomerization, can be reduced or minimized. By reducing, minimizing, or avoiding the amount of hydroprocessing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.Type: GrantFiled: May 20, 2021Date of Patent: July 19, 2022Assignee: ExxonMobil Technology and Engineering CompanyInventors: Matthew H.

Patent number: 5648587Abstract: Disclosed is a process for separating sulfone from a hydrocarbon stream containing a small concentration sulfone by using water as an extraction solvent. The extraction solvent, laden with the removed sulfone, is further processed to separate the extraction solvent and water to thereby produce a sulfone product suitable for reused in an alkylation process or for sale as a dry sulfone end-product.Type: GrantFiled: December 4, 1995Date of Patent: July 15, 1997Assignee: Phillips Petroleum CompanyInventors: Keith W. Hovis, Richard L. Anderson

Patent number: 5648588Abstract: Disclosed is a process for separating sulfone and hydrogen fluoride from hydrocarbon streams containing a concentration of such compounds. An extraction solvent laden with sulfone and HF is contacted with a reversible base in order to remove the HF therefrom. The thus-treated extract stream is separated into a water stream that can be reused as the water extractant and a sulfone stream that is suitably free of HF.Type: GrantFiled: December 8, 1995Date of Patent: July 15, 1997Assignee: Phillips Petroleum CompanyInventors: Richard L. Anderson, Bruce B. Randolph

Patent number: 5639932Abstract: A novel alkylation catalyst is described which is used in processes for alkylating olefin hydrocarbons with isoparaffin hydrocarbons to produce high octane alkylate products suitable for use as blending components of gasoline motor fuel. The novel catalyst comprises a mixture of a hydrogen halide, a sulfone and water and has suitable corrosion properties which permit its utilization in alkylation process systems. The novel alkylation catalyst is utilized in a novel process for alkylating olefin hydrocarbons with isoparaffin hydrocarbons.Type: GrantFiled: May 26, 1995Date of Patent: June 17, 1997Assignee: Phillips Petroleum CompanyInventors: Ronald G. Abbott, Bruce B. Randolph
