Abstract
The process provided herein is concerned with disposal of oxidized sulfur compounds formed by oxidative desulfurization. The process uses solid base catalyst in the presence of a caustic solution or solid base catalyst pretreated with a base and eliminates the need to separate the sulfones from the hydrocarbon streams and recover the hydrocarbons.

1-16. (canceled)
A process for manufacturing a solid base catalyst comprising
- providing solid base catalyst composition including
- a layered double hydroxide of the general formula (I)
- ZnAl2O4.x(ZnO).y(Al2O3) (I)
- wherein x and y are independently between 0 and 2, and
- wherein the total proportion of ZnAl2O4 in the formula (I) is at least 10 percent by weight;
- loading the solid base catalyst composition in a reactor;
- heating the reactor to an effective temperature;
- and
- passing a liquid caustic solution over the solid base catalyst in the reactor for a period of time sufficient to impart alkaline quality to the solid base catalyst.
