Sonochemistry … and desulfurization

“The automobile engine will come, and then I will consider my life's work complete.” Rudolf Christian Karl Diesel (March 18, 1858 – c. September 29, 1913); German inventor and mechanical engineer, famous for the invention of the diesel engine

What I like about this …
“Ultrasound” desulfurization is a technology that has suffered from the controversy surrounding companies that claim to have a technology that works. The article below provides evidence of the results of genuine research that may yield positive results. Take a look.

[Excerpts from Introduction]
Sonochemistry is a new and rapidly growing research field with broad applications in environmental engineering, green chemical synthesis, and processing.
…
Many papers and patents concerning oxidation of sulfides have been published and claimed, including the systems for ODS of diesel fuels. But UAODS of diesel fuels is just the beginning (Mei and Mei, 2003; Dai and Qi, 2007a,b). UAODS technology offers a nonhydrogen consuming, lower capital cost, more sustainable alternative to conventional HDS technology and can be applied as part of an effective strategy for an alternative to revamping intermediate and low-pressure HDS units to produce low sulfur diesel (LSD) and/or ultra-low sulfur diesel (ULSD), or as a means to reduce the operating cost of lowpressure units that have already been revamped. The technology can also be considered as an attractive revamp opportunity for any existing unit where construction of new high-pressure HDS units is the alternative.


In the present work, three types of studies are discussed. First, HDS of highsulfuric FCC diesel fuel is mapped out relevant to our investigations. The purpose of this measurement is to address issues pertaining to these reactive conditions in different remove of sulfur rates. Second, UAODS of high-sulfuric FCC diesel fuels is performed. And last, integrating HDS with UAODS of FCC diesel fuels is preformed to meet the new LSD and/or ULSD specifications.
