Web1. Field of the Invention. The present invention provides for the novel integration of a propylene oxide production sequence with an existing methyl tertiary butyl ether (MTBE) process unit whereby propylene oxide can be economically produced without the need for MTBE production beyond that already produced in the existing unit. 2. WebA stream containing from 8 to 15% by weight of isobutylene and 15 to 50% isobutane can be produced from methanol by using silicalite (S-115) impregnated with oxides of thorium, zirconium, titanium, or manganese. The isobutylene can be recovered from this stream and used in the manufacture of methyl-t-butylether, butyl rubber, polybutenes ...

The main drivers for the MTBE price differential to gasoline in 2024 will be the combination of demand from Mexico and how much MTBE is produced in the US. Another key element affecting fuel consumption will be Mexico's …
WebHarford County, Maryland, found MTBE in wells near several of its filling stations beginning in 2004. This led the state of Maryland to make moves to ban MTBE. In 2005, an Exxon-Mobil station in Fallston, Maryland, was found to be leaking MTBE into the local wells.The discovery resulted in the station being abruptly closed.
