composição de gasolina, método para reduzir o rvp de uma gasolina oxigenada e método para reduzir a limitação do rvp em um estoque de mistura de gasolina na produção de gasolinas oxigenadas

摘要

Compositions of oxygenated gasolines containing isobutanol are disclosed that have reduced vapor pressure compared to those containing a single oxygenate and no isobutanol. Such compositions can be formed at a refinery or at a terminal. Methods of reducing vapor pressure of an oxygenated gasoline are disclosed and methods of reducing vapor pressure constraints upon a refinery in the production of oxygenated gasoline are disclosed. Fundamental properties of isobutanol are disclosed including IR spectrum analysis. Processes and methods for blending and distributing these fuels are also disclosed.
