Effect of 1-Methylnaphthalene Solvent on Cracking of Oil Sand Bitumen with Iron Oxide Catalyst in Steam Atmosphere
Oil sand bitumen Steam catalytic cracking Iron oxide catalyst 1-Methylnaphthalene
2010/9/8
Catalytic cracking of bitumen with steam was examined. The heavy oil fraction of bitumen reacted with active oxygen species generated from steam with the iron oxide catalyst, producing significant amo...
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...
Solvent Extraction of Bitumen from Jordan Oil Shale Assisted by Low Frequency Ultrasound
Jordanian oil shale Low frequency ultrasound Solvent extraction Ultrasonically assisted extraction Bitumen
2010/9/8
In this work, the efficiency of 20 kHz frequency ultrasounds versus the classical stirring procedure was investigated on the solvent extraction of Jordanian El-Lajjun oil shale by employing a horn typ...
Solvent Extraction of Coal Tar Absorption Oil with Continuous Countercurrent Spray Column
Coal tar Absorption oil Solvent extraction Continuous countercurrent operation
2009/7/28
Solvent extraction of absorption oil by aqueous solution of methanol was evaluated using a continuous countercurrent spray column. The structure of the spray column is simple so that the mass transfe...
