biofuels crude oil gasoline, ethanol cointegration
2014/2/27
The world annual biofuel production has exceeded 100 billion litres in 2009. The development of the biofuel production is partly influenced by the government support programs and partly by the develop...
Extraction Equilibrium of Ethanol for Bioethanol Production — Solvent Selection and Liquid-liquid Equilibrium Measurement —
Bioethanol Liquid-liquid equilibrium Distribution coefficient Mixed solvent Separation selectivity UNIFAC estimation
2010/9/8
Ethanol distributions between selected organic and aqueous phases were measured for recovery and concentration of bioethanol from fermented solution. The strategy of solvent selection was based on the...
New Method for Ethanol Synthesis from Dimethyl Ether and Syngas via Two-stage Reaction
Carbonylation Hydrogenation Ethanol synthesis Zeolite catalyst Two-stage reaction Dimethyl ether
2010/9/8
A new method for ethanol synthesis from dimethyl ether (DME) and syngas via a two-stage reaction system was established successfully. In the first stage reaction, H-mordenite zeolite catalyst was used...
Steam Reforming of Ethanol over Co/La1-xSrxBO3 (B = Al, Cr, Mn, Fe) Catalysts
Steam reforming Ethanol Hydrogen production Perovskite Lattice oxygen
2009/8/4
The steam reforming of ethanol for producing hydrogen was evaluated over 5 wt% Co catalysts supported on perovskite-type oxides, La1-xSrxBO3 (B = Al, Cr, Mn, Fe, x = 0-0.2) at 823 K with a molar H2O/C...
Effects of Surface Modification of H-ZSM-5 Catalysts on Direct Transformation of Ethanol into Lower Olefins
Ethanol Propylene Direct synthesis Lanthanum modified H-ZSM-5
2009/8/4
Various H-ZSM-5 catalysts were assessed for ethanol conversion into lower olefins. Ethanol was converted to lower olefins over H-ZSM-5 catalyst without modification. The selectivities for ethylene an...
