“…ETBE is a relatively recent compound and there is little information available in the literature on its emissions (Baur et al 1990;Naman and Allsup 1980;Pecci and Floris 1977;Weber de Menezes et al 2006b;Wells 2008). Since it has been suggested as a candidate for replacing MTBE, it is nonetheless interesting to compare the two additives (MTBE and ETBE), as in the study by Baur et al (1990), on the same SI internal combustion engine.…”

This paper is a review of the available literature on the main features of 11 of the most widely adopted oxygenated additives to base gasoline and diesel, focusing particularly on the emissions from the oxygenates considered as additives. The oxygenated additives studied are methyl tert-butyl ether, ethyl tertiary butyl ether, tert-amyl ethyl ether, tertiary amyl methyl ether, isopropyl ether, dimethyl carbonate, dimethoxymethane, dibutyl ether, diglycol methyl ether, diethyl carbonate, and 2-methoxyethyl acetate.

“…Purification of methyl‐ tert ‐butyl ether (MTBE) and especially separation of a methanol and MTBE mixture are among the most challenging processes in the chemical industry. MTBE is one of a group of chemicals commonly known as oxygenates because they raise the oxygen content of gasoline and help gasoline burn more completely, thereby reducing harmful tailpipe emissions from motor vehicles. It has been shown that the addition of 10%–15% MTBE to gasoline increases the motor octane number by 2–5 .…”

Preparation and characterization of methanol selective membranes based on polyheteroarylene − Cu(I) complexes for purification of methyl tertiary butyl ether

et al. 2017

A comparative study of metal − polymer complexes of Cu(I) with polybenzoxazinoneimide (PBOI) and its prepolymer imide-containing polyamic acid (PAA) as novel membrane materials for methyl tertiary butyl ether (MTBE) purification was undertaken. The structure, physical parameters and transport properties were characterized in detail to analyse the separation performance of the membranes and obtain new knowledge on the interdependence of the chemical structure and physical data with transport parameters. Thermally initiated conversion of PAA − Cu(I) to PBOI − Cu(I) was studied by TGA and DSC. The thermal conversion increases the polymer glass transition temperature and membrane density. Both polymers were applied to pervaporation separation of MTBE from methanol impurities. Membranes based on PAA are highly effective in MTBE purification and preferably permeate methanol. The transport properties of PAA − Cu(I) membrane are compared with those of known membranes.

“…The conventional separation process used for development of environmental senses in recent the reaction mixture is water washing and disyears. [1][2] Specifically, ethanol may be obtained tillation. Because ethanol combined with ETBE from farming products by fermentation, so ETBE can form an azeotropic mixture, a very complex flow sheet with several distillation columns was designed.…”

ABSTRACT:A new kind of membrane was prepared by blending poly(acrylic acid) with cellulose acetate propionate for the separation of ethyl tert-butyl ether and ethanol mixtures. The properties of the membranes were evaluated by the pervaporation separation of mixtures of ethyl tert-butyl ether/ethanol and the sorption experiments. The experimental results showed that the selectivity and the fluxes of this membrane depend on the blend composition and on that of processed feed mixtures. With respect to temperature, the ethanol fluxes obey the Arrhenius equation. The fluxes increase with the increase of the poly(acrylic acid) content in the blended membrane, the ethanol concentration in the feed, and the experimental temperature. But the selectivity decreases as the poly(acrylic acid) content and the experimental temperature are raised up. When the feed composition is varied, this membrane shows the special characteristics at the azeotropic composition. In the vicinity of the azeotropic point, the minimum values of ethanol concentration in the permeate and in sorption solution are obtained. The swelling ratios increase with an increase in the temperature and the ethanol concentration. The ethanol concentration in the sorption solution is also influenced by the temperature and composition of the mixtures. When the temperature increases, the sorption selectivity of the membrane decreases.
