Abstract
The process provided herein is concerned with recovery of hydrocarbons from sulfones using an individual alkali and alkaline-earthy base and a mixture of thereof. As the starting materials are sulfones generated by ODS and commercially inexpensive alkali and alkaline-earth bases, the cost and ecological impact of solid waste disposal is minimized.
Claims25
A process for hydrocarbon recovery from one or more sulfones comprising:
- mixing an one or more alkaline compounds with the sulfone(s);
- retaining the alkaline compound(s) in contact with the sulfone(s) at a temperature less than 380° C. for a period of time sufficient to promote reaction of the sulfone(s) into phenol derivative(s) of the sulfone(s).
