Abstract
A process for the autocatalytic production of organic hydroperoxides and ultra low sulfur diesel boiling range hydrocarbons is disclosed. The organic hydroperoxides react with sulfur compounds to produce sulfones, and the sulfones can be removed from the diesel boiling range hydrocarbons to provide ultra low sulfur diesel.
Claims12
A process for the production of organic hydroperoxides comprising:
- (a) reacting, at a temperature from 110° C. (230° F.) to 170° C. (338° F.), a diesel boiling range hydrocarbon feedstock comprising hydrocarbons in the C9 to C23 range and having a boiling range from 140° C. (284° F.) to 380° C. (716° F.), oxygen and a recycle stream comprising hydrocarbons in the C9 to C23 range and organic hydroperoxides (OHP), in a steady state OHP concentration range from 50 to 5000 wppm oxygen as OHP, to produce a non-distilled product stream comprising hydrocarbons in the C9 to C23 range and an increased concentration of organic hydroperoxides;
- (b) recycling at least a portion of the product stream comprising hydrocarbons in the C9 to C23 range and the increased concentration of organic hydroperoxides, wherein the at least a portion of the product stream is recycled to step (a) so that a steady state OHP concentration range is maintained;
- and
- (c) recovering a stream comprising hydrocarbons in the C9 to C23 range and organic hydroperoxides.

- and
- (d) in an organic sulfur oxidation zone, reacting the stream comprising hydrocarbons in the C9 to C23 range and organic hydroperoxides in the presence of an organic sulfur oxidation catalyst to produce a stream comprising hydrocarbons in the C9 to C23 range and sulfone compounds.
