Embodiment

[0054] The properties of three fuels are compared in Table 2, namely typical base gasoline, RVP adjusted ethanol injection blended gasoline, and gasoline with chemical and injection blends formed using the methods disclosed herein. ethanol fuel. For comparison, RVP was held constant for all three fuels to determine the effect on octane (RON) and to determine the amount that could be produced per day in a typical process. Additionally, for ethanol-containing fuels, the mixture is further restricted to have equal oxygen content.

Abstract

A fuel or fuel blendstock comprising ethanol, ethyl ethers, olefins, and alkanes. In some embodiments, the fuel or fuel blendstock of claim 1, wherein the fuel or fuel blendstock may have an octane number greater than 92 (RON+MON) / 2). In other embodiments, the fuel or fuel blendstock may have a Reid vapor pressure less than 7.2 psi. Also disclosed is a process for the production of a fuel, the process including: contacting ethanol and at least one gasoline fraction including alkanes and olefins in the presence of a catalyst to form a fuel mixture including ethyl ethers, alkanes, unreacted olefins, and unreacted ethanol; and recovering the fuel mixture for use as a gasoline or gasoline blendstock without separation of the ethanol from the fuel mixture.

Description

technical field [0001] Embodiments disclosed herein relate generally to methods of using renewable resources such as ethanol as fuel components. In another aspect, embodiments disclosed herein relate to a fuel composition comprising alkanes, alkenes, ethanol, and ethyl ether. More specifically, embodiments disclosed herein relate to various methods for chemical and splash blending of ethanol with gasoline fractions. Background technique [0002] Fuel producers are increasingly under pressure to use renewable resources as blending feedstock. Ethanol is frequently mentioned as a prime example of such a material. Of all the easily produced renewable compounds, ethanol is the most suitable for use in gasoline. In fact, engines can be designed to run on pure ethanol as well as modifications in the fuel system. [0003] For the economy as a whole, ethanol use can increase energy independence. This is due to the fact that agricultural carbohydrate resources can be produced alm...
