Analysis of the Effects of BioButanol and BioEthanol on the Vapour Pressure Gasoline

Abstract

With the gradual introduction of biofuels II. generation, attention will be devoted to research and development of wider use of fuels of vegetable origin focused on the possibility of making and using better quality motor fuel than bioethanol. Biobutanol (n-Butanol, Butan-1-ol) is an alternative to bioethanol, which is currently commercially produced and used as a component of motor gasoline or as E85. The article introduces the principle of the evaporation of liquids and creating vapor pressure gasoline fuels with bioethanol and biobutanol. The release of particles from the liquid surface (evaporation) is a process that more or less is intensively carried out at each temperature. The saturation of vapor pressure in the system at a given temperature is at an equilibrium of gas and liquid phases. The introduction of biofuels as renewable sources brings with it a number of technical problems. The addition of bioethanol and other oxygenates in gasoline, is associated with a change in vapor pressure, which of course also applies to biobutanol. The analysis of the variance evaluates the vapor pressure characteristics of both alcohol fuels and their properties as a prerequisite for the potential introduction of biobutanol for commercial use as fuel in internal combustion engines. The article reviews the experimental analysis of the vapor pressure and selected compounds including the additives MTBE and ETBE.
