Consider new technologies to replace MTBE

Processing methods enable using 'stranded' MTBE facilities and feedstocks for high-octane applications

Over the last decade, methyl tertiary butyl ether (MTBE) became the major additive in reformulated gasoline (RFG) and was used to reduce air pollution from automobile-engine exhaust. Recently because of concerns over potential water pollution problems caused by leaking underground gasoline storage tanks, more U.S. state governments are adopting legislation to either phase out or restrict the MTBE usage as a gasoline additive. To replace the loss of MTBE from the gasoline octane pool, as well as find a new usage for iso-butene (the raw material of MTBE), the technology of dimerizing iso-butene to iso-octene and subsequent iso-octene hydrogenation to iso-octane is fast being developed as an MT
