1_05/2008Cover Picture: Green Gasoline by Catalytic Fast Pyrolysis of Solid Biomass Derived Compounds (ChemSusChem 5/2008)

The cover picture shows a scheme for the conversion of cellulose into gasoline-range aromatics by catalytic fast pyrolysis. Owing to its recalcitrance, there are currently no economical processes for the direct conversion of lignocellulosic biomass into useful chemicals and fuels. G. W. Huber et al. report in the Communication on page 397 ff. a process that they have developed which involves the thermal decomposition of cellulose to smaller volatile oxygenates as the first step. These biomass-derived species then enter the pores of the zeolite catalyst ZSM5, where they undergo a series of dehydration, decarbonylation, decarboxylation, isomerization, oligomerization, and dehydrogenation reactions that lead to aromatics, including naphthalene, ethylbenzene, toluene, and benzene, and by-products such as carbon monoxide, carbon dioxide, and water. All this takes place at short residence times (less than 2 min) at 600 °C in a single reactor.
