Hydrolysis of sodium borohydride (NaBH 4 ) over metal catalyst is being accepted as a potential technology to deliver H 2 for portable fuel cells. However, unresolved issues such as minimizing the amount of water and nature of hydration by-product limit the hydrogen storage capacities of NaBH 4 ...

Energy efficient capture of CO 2 released from coal based power plants is a major challenge to reduce greenhouse gas emissions. The existing commercial technologies require substantial energy inputs in the form of heat and vacuum which leads to around 30 % parasitic energy loss. To overcome this...

Anthropogenic carbon dioxide (CO 2 ) emissions, major contributors to the greenhouse effect, are considered as the main cause of global warming. So, decrease of CO 2 emitted by large industrial combustion sources or power plants, is an important scientific goal. One of the approaches is based on CO...

Research over several decades by several institutions has shown that alkali-promoted metal sulfide catalysts are capable of producing mixed alcohols from syngas with high selectivity and yield. Unfortunately, process models suggest that syngas to mixed alcohol processes, and especially...

A multiyear DOE-supported study was completed to identify, determine, and understand fundamental burn characteristics and properties of alternative fuel sources to replace coal for energy generation, with emphasis on impacts in cement processing. Portland cement manufacturing involves the...

Topical 6: Lignocelluosics: Biorefineries and Sustainable Energy T6007 Thermalchemical Conversion I AIChE 2011, October 16~21, 2011 Minneapolis, MN Pretreatment of Loblolly Pine for Fast Pyrolysis via Torrefaction Jiajia Meng, David Tilotta, and Sunkyu Park* Department of Forest Biomaterials, North...

A three-dimensional steady state computational fluid dynamics model is developed for a solar receiver consisting of a reflective cavity with a windowed aperture enclosing an array of five tubes. The computational model couples radiative transfer with fluid flow, heat transfer, mass transfer, and...

Microalgae harvest contributes a large portion of cost for microalgae-to-biofuels production. Most current harvest technologies including chemical and mechanical methods are only economically feasible for production of high-value products due to the costs. In this work, we are describing a new...

Abstract Renewable energy, including wind and solar, could supply a significant amount of electrical energy in the United States and around the world. However, despite the benefits of wind and solar, integration of these intermittent sources into the electrical grid system poses major challenges to...

Fuels production through metal oxide redox cycling can be completely renewable if reduction temperatures are achieved using concentrated solar energy. Many combinations of metal oxides have been investigated over the years and cobalt ferrites show much promise as they have good thermodynamic...
