Patent number: 4200520Abstract: The octane number of a cracked naphtha can be significantly improved in a catalytic cracking unit, without significant decrease in naphtha yield, by maintaining certain critical concentrations of metals on the catalyst, suitably by blending or adding a heavy metals-containing component to the gas oil feed.Type: GrantFiled: January 30, 1978Date of Patent: April 29, 1980Assignee: Exxon Research & Engineering Co.Inventors: Elroy M.

Patent number: 4176049Abstract: A process which comprises recracking a cracked naphtha feed containing up to about 60 percent, suitably from about 20 to about 40 percent olefins, over a crystalline aluminosilicate zeolite catalyst to further crack the naphtha and saturate at least about 50 percent of the olefins, preferably from about 90 percent to about 100 percent of the olefins, based on the weight of said cracked naphtha feed. In a preferred combination a gas oil is catalytically cracked in a first stage to produce a cat cracked naphtha product of high olefin content, and an intermediate boiling component thereof is recracked as a feed in a second stage over a zeolite catalyst to saturate the olefins, and hydrodenitrogenate and hydrodesulfurize said cat cracked naphtha. The recracked cat cracked naphtha is then hydrotreated at low to mild severities and then catalytically reformed (hydroformed) to produce high octane gasoline.Type: GrantFiled: April 3, 1978Date of Patent: November 27, 1979Assignee: Exxon Research & Engineering Co.Inventors: William E.

Patent number: 4149965Abstract: A naphtha hydrorefining process is initiated by contacting an olefinic naphtha feed at hydrorefining conditions including a pressure below about 200 psig, with hydrogen and a catalyst that has been partially deactivated by treating a fresh or a regenerated catalyst with a substantially non-metals containing hydrocarbonaceous oil in the presence of hydrogen under conditions sufficient to decrease the hydrogenation activity of the catalyst.Type: GrantFiled: June 27, 1978Date of Patent: April 17, 1979Assignee: Exxon Research & Engineering Co.Inventors: Lloyd A.

Patent number: 4131537Abstract: A hydrofining process wherein an olefinic naphtha hydrocarbon feed in vapor phase is contacted, in a fixed bed, with a catalyst of small particle size at low pressure. Suitably, a catalyst of average particle size no greater than, or less than about 1/20 inch is employed. Preferably, the catalyst is of average particle size ranging from about 200 microns to about 1/20 inch, and more preferably the catalyst is of average particle size ranging from about 1/40 inch to about 1/20 inch. By the use of such catalyst at total pressures ranging from about 60 to about 300 psig, preferably from about 80 to about 200 psig, it has been found that the rate of hydrodesulfurization of the naphtha feed is considerably increased, and yet there is significantly less saturation of the olefins, and other nonreactive hydrocarbons with hydrogen.Type: GrantFiled: October 4, 1977Date of Patent: December 26, 1978Assignee: Exxon Research & Engineering Co.Inventors: William E. Winter, Mamerto G. Luzarraga

Patent number: 4062762Abstract: A sulfur-containing naphtha is separated into at least three fractions. Each fraction is desulfurized separately by a different desulfurization method. Subsequently, the desulfurized fractions are recombined. The intermediate boiling point naphtha fraction is desulfurized by an alkali metal desulfurization process, preferably in the presence of added hydrogen.Type: GrantFiled: September 14, 1976Date of Patent: December 13, 1977Inventors: Kent A.
