Abstract: A method for purifying a sulfur-containing fuel oil comprising (a) contacting in a first reaction mixture the sulfur-containing fuel oil with an exogenous binary catalyst, hydrogen peroxide, and a water-soluble acid at a temperature in a range of from about 25° C. to about 150° C. to provide a first oxidized mixture; and (b) separating at least one oxidized sulfur compound from the first oxidized mixture to provide a purified fuel oil. The first reaction mixture may further comprise a phase transfer catalyst. Furthermore, the sulfur-containing fuel oil may be deasphalted prior to contacting with the catalyst, hydrogen peroxide, and the water-soluble acid.

Abstract: A method for purifying a sulfur-containing fuel oil comprising (a) contacting the fuel oil with a supported exogenous binary catalyst and oxygen at a temperature in a range of from about 25° C. to about 150° C., and at a pressure in a range of from about 1 atmosphere to about 150 atmospheres to provide a first oxidized mixture; and (b) separating at least one oxidized sulfur compound from the first oxidized mixture to a provide a purified fuel oil. In one embodiment, the sulfur-containing fuel oil is deasphalted prior to contacting with the supported exogenous binary catalyst and oxygen.

Abstract: A method of preparing a contact mass is provided comprising reacting silicon and a cuprous chloride to form a concentrated, catalytic contact mass. Furthermore, a method for making an alkylhalosilane using the aforementioned contact mass is provided comprising effecting reaction between an alkyl halide and silicon in the presence of said concentrated contact mass to produce alkylhalosilane.
