Methanol to gasoline: 14C tracer studies of the conversion of methanol/higher alcohol mixtures over ZSM-5

A series of experiments using a ZSM-5 catalyst and a reactor feed of either methanol mixed with carbon-14 labeled ethanol, 1-propanol or 1-pentanol or carbon-14 labeled methanol mixed with ethanol, 1-propanol or 1-pentanol was carried out. For conversions at 180, 200 or 300°C, the carbon-14 distribu...

Summary:A series of experiments using a ZSM-5 catalyst and a reactor feed of either methanol mixed with carbon-14 labeled ethanol, 1-propanol or 1-pentanol or carbon-14 labeled methanol mixed with ethanol, 1-propanol or 1-pentanol was carried out. For conversions at 180, 200 or 300°C, the carbon-14 distribution indicated nearly complete equilibration of the carbons of the labeled and unlabeled alcohols. In the present study, the data show that isotope equilibration occurs within carbon number fractions and among compounds in each of the C 2-C 4 fractions. These data demonstrate also that carbon isotope equilibration within C 3 + compounds is rapid compared to chain growth; this conclusion appears to apply for earlier tracer studies as well. Methanol is also the dominant source of the methane formed during conversion of the alcohol mixtures. Methanol is also the dominant source of the C 2 products, except when ethanol is the second alcohol.
