Methanol Production for Renewable Energy Storage and Distribution
Methanol production technology and systems are being developed to provide an economically viable fuel from a renewable energy source. Neither fossil fuel nor biological feedstock is required. The energy is principally used to extract hydrogen [...]
Novel Membrane Technology for Green Ethylene Production
Balachandran U., Lee T.H., Dorris S.E., Scouten C.G., Marshall C.L., Argonne National Laboratory, US
Today ethylene is produced (approximately 60 billion pounds in 2005 in U.S.A. alone) by thermal cracking of ethane in presence of steam requiring substantial energy input. The equilibrium conversion is thermodynamically limited. Because of direct [...]
Bio Mass for CO2 Neutral Steel Production
The paper presents a process to strongly increase the efficiency of bio mass as energy source in steel production by direct use of wood chips instead of charcoal combined with a new microwave based heating [...]
Complete Microbiological Fuel Cell: A Photosynthetic Cathode Coupled to a Fermentative Anode
A completely biological microbial fuel cell (MFC), using photosynthetic growth at the cathode and yeast fermentation at the anode, has been developed and operated successfully for the first time. The photosynthetic culture, Chlorella vulgaris, was [...]
Nano-docking stations for synfuels catalysts on carbon nanotubes
Carbon nanotubes (CNTs) represent a distinctive class of catalyst supports and provide promising scenarios for catalytic reactions including fuel synthesis. The mobility of supported catalytic nanoparticles (NPs) on CNTs typically results in agglomeration leading to [...]
Analysis of the US Fuel Ethanol Industry and Market Expectations
From humble beginnings as part of Henry Ford’s vision of an agricultural based transportation industry and a rebirth as a fuel additive, ethanol is quickly approaching a 10% share of the US gasoline market. Fuel [...]
Catalytic Conversion of Biomass to Hydrocarbons
Virent Energy Systems, Inc.’s patented Aqueous-Phase Reforming (BioFormingTM ) process enables the economical and energy efficient use of plant based sugars to generate the many hydrocarbon products that drive the world economy. Virent’s patented catalytic [...]
Clean Waste Tech: Anaerobic Composting in Bioreactor Landfills
The controlled bioreactor landfill has been demonstrated at progressively larger scales, now up to 300,000 tons waste in multiple cells, since 1994. The approach enables recovery of renewable methane energy from landfills to maximum potential. [...]
Direct Injection of Flue Gas into Coal Seams for Carbon Storage and Methane Production
Investigation into the potential for flue gases from a 2400MW coal fired power station to be injected into the nearby deep coal seams under the plant for carbon capture and storage. Directional drilling techniques will [...]
