Oxidative route 'cleans up' diesel
A novel, low-emission technology uses an oxidative chemistry to desulfurize crude oil or refined products. The process-UniPure ASR-2-has been developed by UniPure Corp. in cooperation with Texaco and Mustang Engineering. It is an alternative ultra-low desulfurization process that readily converts highly substituted thiophenic compounds into sulfones; it does not consume hydrogen.
UniPure ASR-2 (Fig. 1) is a two-step process. The sulfur species are oxidized into sulfones using an oxidant carried in the aqueous phase with a liquid catalyst. The reaction occurs at near-atmospheric pressure and mild temperatures, less than 250°F.
