Converting Sugars to Biofuels: Ethanol and Beyond
To date, the most significant sources of biofuels are starch- or sugarcane-based ethanol, which have been industrially produced in large quantities in the USA and Brazil, respectively. However, the ultimate goal of biofuel production is to produce fuels from lignocellulosic biomass-derived sugars with optimal fuel properties and compatibility with the existing fuel distribution infrastructure. ...
متن کاملConverting homogeneous to heterogeneous catalysts
Homogeneous transition metal complex catalysts for organic industrial processes are converted to catalysts which are heterogeneous with respect to the reactants, and which have substantially equal catalytic activity to the homogeneous catalysts. This is done by reacting a normally homogeneous transition metal complex catalyst with a metal bridging ligand which substantially duplicates the ligan...
متن کاملTAP reactor investigation of methane coupling over samarium oxide catalysts
The adsorption and reaction characteristics of a Ba/Sr/Sma03 catalyst for methane coupling has been investigated using the TAP (Temporal Analysis of Products) reactor system. Puhed adsorption experiments using methane, oxygen and krypton at temperatures ranging from 17°C to 300°C show that the transient response of methane is similar to that of Kr and is either not adaorbed, or weakly adsorbed ...
متن کاملDirect and Multistep Conversion of Lignin to Biofuels
Though the rapid development of human society, concerns on the fossil fuel shortage, pollution, and end-of-life disposal issues are attracting the most attention nowadays. Therefore, more efforts from governments, industries, and research institutes have been paid to the sustainable development than it has ever been done before. Cellulose, lignin and hemicellulose are the major components of bi...
متن کاملAlkali-O2 oxidized lignin – A bio-based concrete plasticizer
Commercial wheat straw soda lignin was used to develop an alkali-O2 oxidation method to produce a ready-to-use solution for concrete plasticizing (cement dispersing). Lignin characterization was done directly from the solution. Depending on conditions, oxidation primarily induced either condensation or degradation of lignin. Thus, both the negative charge and the molar mass of the lignin were c...
