With no market for MTBE in the U.S., refiners could decide to use the isobutylene previously used to make MTBE for other gasoline blending components. Three such products are alkylate, a moderate-to-high octane gasoline blend stock; isooctane, a high octane (100 octane) blendstock; and isooctene, which has a slightly higher octane level than isooctane. According to U.S. EPA's Regulation of Fuels and Fuel Additives: Renewable Fuel Standard Program, released earlier this year, alkylate is the most cost-effective way for refiners to reuse isobutylene, even when isooctane and isooctene's higher octane rating is taken into account. Therefore, EPA expects that most MTBE units within or adjacent to refineries will be converted to produce alkylate, as will most ethylene cracker plants.
