109	Polished turbine fuel	US16780463	2020-02-03	US11015134B2	2021-05-25	Mohammed Wohaibi; Tom F. Pruitt
Turbine fuel provided for large-scale land based turbines used by utilities for producing electricity and desalinated water, and for large mobile engines and turbines in marine and remote applications where only liquid fuels are available. Use results in less corrosion, ash formation and emissions (NOx, SOx, CO2 and noxious metals) than firing contaminated heavy crude, refinery residual oils or high sulfur fuel oils. Manufacture is by decontaminating crude oils, non-conventional crudes, and other highly contaminated feeds. Each fuel is produced as a single product of unit operations, not ex-plant blend of various refinery products, yet using an apparatus configuration less complex than conventional crude oil refining. These fuels can be fired by advanced high efficiency turbines of combined cycle power plants having hot flow paths and heat recovery steam generation systems susceptible to corrosion, which systems cannot otherwise risk contaminated heavy crudes or refinery residual oils feeds.

115	Methods and Systems for Combined Oxidative and Hydrotreatment of Hydrocarbon Fuel	US14417091	2013-07-23	US20150210949A1	2015-07-30	Roger Kai Lott; Kamalul Arifin Yusof
A method for combined reductive and oxidative treatment of liquid hydrocarbon feedstock to form upgraded liquid fuel having increased cetane number and reduced sulfur content. The yield of upgraded liquid fuel having a given cetane number is higher than processes than only increase cetane number by oxidative treatment. The feedstock can be initially hydrotreated to reduce sulfur content followed by oxidative treatment to increase cetane number. A first portion of a hydrotreated intermediate stream can be oxidatively treated to yield high cetane number blending stock, which is combined with a second portion of the hydrotreated intermediate stream to yield upgraded liquid fuel having increased cetane number and reduced sulfur content. Combining hydrotreatment with oxidative treatment facilitated by high energy cavitation maximizes yield and fuel quality.
116	TARGETED DESULFURIZATION PROCESS AND APPARATUS INTEGRATING GAS PHASE OXIDATIVE DESULFURIZATION AND HYDRODESULFURIZATION TO PRODUCE DIESEL FUEL HAVING AN ULTRA-LOW LEVEL OF ORGANOSULFUR COMPOUNDS	US13741101	2013-01-14	US20140197074A1	2014-07-17	Abdennour Bourane; Omer Refa Koseoglu; Zinfer Ismagilov; Svetlana Yashnik; Mikhail Kerzhentsev; Valentin Parmon
Desulfurization of hydrocarbon feeds is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A first fraction contains refractory organosulfur compounds, which boils at or above the target cut point temperature. A second fraction boiling below the target cut point temperature is substantially free of refractory sulfur-containing compounds. The second fraction is contacted with a hydrodesulfurization catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level. The first fraction is contacted with gaseous oxidizing agent over an oxidation catalyst having a formula CuxZn1-xAl2O4 in a gas phase catalytic oxidation reaction zone to convert the refractory organosulfur compounds to SOx and low sulfur hydrocarbons. The by-product SOx is subsequently removed, producing a stream containing a reduced level of organo sulfur compounds.

A process for concurrently fractionating and hydrotreating of a full range naphtha stream.

120	Hydrocarbon upgrading process	US925001	1992-08-05	US5413698A	1995-05-09	David L. Fletcher; Mohsen N. Harandi; Michael S. Sarli; Stuart S. Shih
Low sulfur gasoline of relatively high octane number is produced from a catalytically cracked, sulfur-containing naphtha by hydrodesulfurization followed by treatment in a second step over a a first catalyst zone comprising a large pore size zeolite material and a second catalyst zone comprising an intermediate pore size material. Preferably, the large pore size material is zeolite beta and the intermediate pore size material is ZSM-5. The treatment in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product with an octane number comparable to that of the feed naphtha. In favorable cases, using feeds of extended end point such as heavy naphthas with 95 percent points above about 380.degree. F. (about 193.degree. C.), improvements in both product octane and yield relative to the feed may be obtained.
