US 6162352 AAbstract
A catalyst composition containing a sulfided mixture of a zinc spinel, a zeolite, alumina, cobalt and molybdenum, and a method of preparing such catalyst composition, are disclosed. The thus-obtained catalyst composition is employed as a catalyst in the hydrodesulfurization of a hydrocarbon feedstock containing gasoline.
1. A catalyst composition comprising a sulfided composition comprising a zinc spinel, a zeolite, alumina, cobalt and molybdenum.
It is well known in the art to reduce the level of sulfur-containing hydrocarbons in gasoline by contacting the hydrocarbon feedstock with a hydrodesulfurization catalyst in the presence of hydrogen. The problem with most of the hydrodesulfurization catalysts and/or processes is the undesired saturation of high octane aromatic and olefinic compounds contained in the gasoline, which lowers the research octane number (RON) of the gasoline. The RON can be determined using ASTM Test Method D2699-97ae1. This lowering of the RON can require a costly further treatment of the desulfurized gasoline in order to restore the gasoline RON to, or close to, its original value. Thus, the development of catalysts and/or processes for desulfurization of gasoline which maintain the RON of the gasoline at or near its original value is desirable to the industry and would be a great benefit to the economy.
It is an object of the present invention to provide a novel catalyst composition effective for upgrading gasoline.
The inventive catalyst composition comprises, consists of, or consists essentially of a sulfided composition comprising, consisting of, or consisting essentially of a zinc spinel, a zeolite, alumina, cobalt and molybdenum.
This example illustrates the preparation of catalysts which were subsequently tested as catalysts in the hydrodesulfurization of a hydrocarbon feedstock.
This example illustrates the use of the catalysts from Example I in the hydrodesulfurization of a catalytically cracked gasoline (CCG) feed. For each of the following runs, a 5 mL. quantity of catalyst was placed in a stainless steel tube reactor (length: about 18 inches; diameter: about 0.5 inch) and the CCG feed to the reactor was 20 mL/hr., unless otherwise stated. The CCG feed contained 298 ppmw sulfur and had a calculated RON of 89.2. Calculation of octane numbers in this example were performed based on the measured octane numbers of the pure components of the streams. A hydrogen flow was also passed through the reactor at a flow rate of 15.6 L/hr.
