Abstract: Biochemical conversion is a promising route to produce fuels and chemicals from cellulosic biomass. A key step in the process is biomass liquefaction, where enzymes are used to break down pretreated cellulosic particles. During this process, drastic changes in the mechanical properties of...

The world currently faces an enormous energy challenge. LanzaTech responds to this challenge by capturing and beneficially reusing waste carbon to make low carbon fuels and chemicals. The International Energy Outlook, in its 2010 reference case, projects that world primary energy consumption will...

Growing demand for clean fuels has led to a renewed urgency in the search for alternative fuels. With the recent shale gas development initiatives, natural gas is poised to capture a much larger share of the energy market. Being clean-burning, natural gas provides many environmental advantages over...

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...

Ordered mesoporous Zr-doped TiO 2 /ZnO material is currently being investigated for band gap tuning and higher loadings of photo-sensitizer. Utilization of such mesoporous materials thereby offers an opportunity to sensitize semiconductor with higher sensitizer loadings leading to effective charge...

Large scale implementation of CO2 geologic sequestration requires detailed uncertainty analysis and risk assessment for leakage potential. Probabilistic risk assessment based on Monte Carlo simulation is one option for quantifying the risk. It involves repeated random realizations of a simulator to...

One key parameter in Chemical Looping Combustion (CLC) is the oxygen transport capacity of the CLC materials between the two process reactors; in practice, it may be limited by a combination of many factors, including the metal content of the inert binder, the oxygen uptake and release kinetics and...

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...

Since OFMSW is...

An efficient and sustainable energy crop production system is essential for the success of the emerging biorefinery industry. However, there is currently a significant lack of understanding regarding the development and dynamics of the biomass feedstock market upstream of the biorefinery, which is...
