Gasoline minus MTBE
Article Abstract:
The California Air Resources Board (CARB) has approved new regulations that would require refiners to produce reformulated gasoline without methyl tert-butyl ether (MTBE). The rules allow refiners to make reformulated gasoline with or without an oxygenate as long as the fuel meets state emission standards. The changes are estimated to add around 6.5 cents per gallon in the production of reformulated gasoline.

Gasoline sulfur reduction without octane loss
Article Abstract:
UOP LLC and Intevep have developed a new hydrotreating process that can reduce the sulfur content of gasoline to 30 ppm and control the octane level. The novel method will undergo commercial testing at two unnamed refineries using FCC naphtha streams. The dual-catalyst ISAL process treats naphtha at 300 to 400 degrees C and 400 to 700 psig. The octane loss is compensated by isomerization and other octane-enhancing reactions.

All sides pumped for MTBE ban
Article Abstract:
Ethanol is considered the only feasible option to replace methyl tert- butyl ether (MTBE) in reformulated gasoline. MTBE is already being phased out in different states, including California, New York, New Jersey and Connecticut. Petroleum refineries are looking at ethanol as the practical option to comply with the Clear Air Act, although the alternative oxygenate also poses problems of availability.
