Vapor–Liquid Equilibrium Measurements of Ether Alcohol Blends for Investigation on Reformulated Gas

“…Comparisons and Predictions. The data sets reported by Clark et al 7 for MTBE + 2,2,4-trimethylpentane at 298.45 and 322.88 K were considered reliable for comparison with those in this study as their data were measured using a static cell. However, the data sets in this study could not be matched directly with those of Clark et al 7 since the temperatures at which the measurements were done differ.…”

“…In addition, recent VLE data for MTBE and isooctane at 318.1 K was reported by Liebergesell et al 9 involving a mililiter-scale setup using Raman spectroscopic phase equilibrium characterization, while isobaric data at 101. 3 reported for the binary and ternary systems involving MTBE and i-octane by Watanabe et al 10 In the studies available from Clark et al, 7 two sets of isothermal data were measured for MTBE + 2,2,4-trimethylpentane at (298.45 and 322.88) K. Their precise P−x data for the latter temperature was compared with our measurement as a test of our apparatus and procedures. Moreau et al 11 and Goral et al 12 reported experimental P−x isothermal data at for MTBE + 1-pentanol at 313.15 K. A list of existing literature for binary systems of MTBE + 2,2,4trimethylpentane as well as MTBE + 1-pentano1 with the type of data and conditions at which the data were measured are presented in Table 1.…”

“…Isobaric VLE data for the MTBE + 2,2,4,-trimethylpentane have been reported in the literature by Reddy et al Other authors such as Wu et al and Clark et al as well as Bernatová and Wichterle, have reported isothermal VLE data for the binary mixtures of MTBE with 4- and 11-component simulated gasoline mixtures, P – x isothermal data for MTBE + ( n -butane, 2,2,4-trimethylpentanes, 2-methylbutane, and o -xylene) systems, and MTBE with tert -butanol and 2,2,4-trimethylpentane, respectively. In addition, recent VLE data for MTBE and iso-octane at 318.1 K was reported by Liebergesell et al involving a mililiter-scale setup using Raman spectroscopic phase equilibrium characterization, while isobaric data at 101.3 kPa was reported for the binary and ternary systems involving MTBE and i -octane by Watanabe et al .…”

“…The MTBE and 2,2,4-trimethypentane pure component vapor pressures in this study were compared with those re-evaluated using the NIST ThermoData Engine (TDE) software implemented in ASPEN 24 and the prediction using regressed parameters obtained from Clark et al 7 The results obtained show systematic deviations of 0.57 and 0.07 kPa from NIST and 0.55 and 0.08 kPa from Clark et al's prediction at the temperature of 317.2 K. These reported deviations may be due to the MTBE purity differences. For the 2,2,4-trimethylpentane + 1-pentanol, the only available data in the literature for comparison are the P−x data reported by Moreau et al, 11 and Goral et al, 12 with both measurements at 313.15 K using a static total pressure cell.…”

Syngas formation from gasoline in adiabatic reactor: Thermodynamic approach and experimental observations

“…These can exhibit reasonably similar or distinctly different behavior depending on the composition of the mixture, an effect particularly noticeable with the addition of other reagents. Thus, a model fuel for gasoline is required which is sufficiently flexible to incorporate a large number of compounds/interactions and provide good results [14].…”
