About MTBE
About MTBE. MTBE (a.k.a. Methyl tert-Butyl Ether) is a volatile, flammable, and colorless liquid with a minty smell. This ether is a major compound in the octane enhancer industry, its main application area. The remaining MTBE is used as a solvent and in the production of other chemical compounds. It is produced by the reaction of methanol and isobutylene (2-methyl-1-propene) in the liquid state.
The demand for MTBE largely increased in the late 1970s, amid the phase-out of lead as an octane enhancer. Indeed, MTBE low cost, high octane value, oxygen content, and easy incorporation into gasoline lead to a significant increase in its consumption in the 1980s, as a substitute for tetraethyl lead in gasoline. The use of MTBE was also stimulated by the governments to meet air quality goals since it reduces motor vehicle emissions, air toxic emissions, and pollutants that form ground-level ozone. Since then, MTBE has been mainly produced from mixed butylenes from ethylene crackers and from fluid catalytic crackers, catalytic butane dehydrogenation, or tert-butyl alcohol dehydration.
In the 1990s, concerns about the safety of using MTBE arose in light of contaminations of surface and groundwater, related to leakings from underground storage tanks and pipelines: the MTBE, having high solubility in water and low vapor pressure, readily transfers to the groundwater. In this context, since mid-2000s, gasoline manufacturers, to comply with new environmental legislation, started replacing MTBE by renewable, safer alternatives, mainly ethanol and ETBE (ethyl tertiary butyl ether). Nowadays, MTBE is still used as a gasoline additive outside of the US, mainly in countries in the Middle East and Asia Pacific. In the United States, MTBE is used in the manufacture of high-purity isobutylene (HPIB), but most of its production targets export markets, mainly Latin America.
MTBE Production. MTBE production pathways are mainly related to the sources of isobutylene consumed. Four major sources of isobutylene are utilized: C4 stream (raffinate-1) from steam cracking units, C4 stream from refinery catalytic crackers after butadiene extraction, on purpose isomerization and dehydrogenation of butane to isobutylene, and the dehydration of tert-butyl alcohol. Raw materials and the respective production processes employed in the manufacturing of MTBE are listed below.
- Raffinate I/C4-stream, refinery + methanol (ether formation; coproduced with raffinate II),
- t-Butanol + methanol (Arco MTBE process),
- Isobutylene + methanol (ether formation)
MTBE is starting material for the manufacture of high-purity polymer-grade isobutylene (HPIB), used in turn in the production of butyl rubber and highly reactive polyisobutylene (HRPIB).
