Summary

As a result of the effort to lower air pollution, the complete gasoline infrastructure (refineries, filling stations, etc.) has to be adapted to unleaded fuel grades and fuel has to comply with basically three criteria: octane boosting (precondition for high compression ratio in the engine), favorable combustion properties (low engine-out emissions) and low vapor pressure at ambient temperature (reducing the evaporative emission of unhealthy hybrocarbons). Among suitable compounds, MTBE is most attractive. It is the product of an exothermic reaction of isobutene with methanol. The predicted demand of MTBE is approximately of 20 large MTBE plants installed worldwide by the year 2000. But if methanol supply does not seem to be critical, the only source for isobutene which can be expanded in a matching manner is the selective dehydrogenation of satured C4 hydrocarbons, which can be recovered from natural gas or gas-well crude oil. Linde AG, Process Engineering and Contracting Divison has developed proven technologies to recover C4 hydrocarbons in an optimum and economical manner. J.V.
