Article Abstract:
Petro Star Inc of Anchorage, AK, has developed an inexpensive alternative technique for removing sulfur from diesel fuel through selective oxidation. The method, which has been presented at the American Chemical Society National Meeting in San Francisco, CA, from Mar 26-30, 2000, is capable of reducing sulfur content from diesel fuel from 4,200 ppmw to 10 ppmw. The tecnique is estimated to cost under $2.50/bbl compared to $3.50- $5.50/bbl using conventional hydrodesulfurization technology.

Article Abstract:
Akzo Nobel NV will begin using improved manufacturing technologies for two lines of fluid catalytic cracking (FCC) catalysts at its plant in Pasadena, TX, in the fall of 2000. The technologies, which are called Topaz and Jade, allows the production of FCCs with characteristics that can be specifically tailored to the requiremets of residual oil processing. These include reduced FCC emissions as well as improved activity and selectivity.

Article Abstract:
GTC Technology has developed a new process for the simultaneous removal of sulfur and benzene from gasoline. The GT-DeSulf process can reduce sulfur to 30 ppm and recover benzene, toluene and xylenes. On the other hand, proprietary solvents are used in removing sulfur and aromatics through extractive distillation at 20 to 40 psig. Two process streams would then leave the GT-Desulf unit, an olefins-rich gasoline stream and a concentrated aromatics fraction containing sulfur compounds.
