The Implications of Bioenergy Derived From Forests for Net Greenhouse Gas Emissions

Nov 9, 2010

Werner A. Kurz

Greenhouse gas (GHG) accounting systems consider bioenergy from forests as carbon neutral because, under international greenhouse gas accounting rules, the carbon contained in wood is deemed emitted to the atmosphere at the time of transfer out of the forest ecosystem. This accounting...

Recent Research Development In Biomass Conversion to Advanced Bio-Fuels

Nov 8, 2010

Johnathan E. Holladay

The United States is abundant in biomass resources. The Pacific Northwest National Laboratory (PNNL) have been conducting research on conversion of biomass into chemical products and advanced fuels for several decades. In this presentation, the author will discuss significant research advancement,...

Artificial Photosynthesis: The Future of Renewable Fuels and Chemicals

Nov 8, 2010

Rich Masel

This presentation will provide an overview and research vision of catalytic and reaction engineering technologies for conversion of CO2 into re-usable energy and/or products at productivity and energy efficiency substantially higher than the natural, photosynthesis process.

More Heat than Light: Opportunities for Extremely Thermophilic Microorganisms and Enzymes in Biofuels

SBE Webinar

Aug 25, 2010

Robert Kelly

The recent interest in biofuels has motivated a closer look at microorganisms from extremely high temperature environments, not only for their capacity to deconstruct the carbohydrate content of plant biomass but also for novel metabolic pathways

Biological Synthesis of Fuels and Chemicals

Global energy and climate problems have stimulated increased efforts in synthesizing fuels and chemicals from renewable resources.

Biomass/Bioenergy Patent Landscape: Past, Present & Future

Metro NY Section Webinar

May 17, 2010

Barry Schindler

Barry J. Schindler, Esq., of Greenberg Traurig LLP's Patent Prosecution Group, addresses Intellectual Properties Issues for chemical engineers engaged in the business of biomass.

Non-Thermal Plasma Reforming of Refractory Tars and Oils Generated by Biomass Gasification

Mar 22, 2010

J. Hartvigsen

One of the barriers to wider use of many kinds of biomass is the fact that they generate refractory tars and oils when gasified. These compounds cause difficulty when they are passed to downstream components in the system by causing plugging and drop in performance. The compounds can be condensed...

Optimization of a Pilot Plant for Production of Biodiesel From Jatropha Curcas L. Oil

Nov 11, 2009

Rogelio Sotelo-Boyas

An optimized process on pilot plant scale was carried out for the production of biodiesel from Mexican jatropha curcas L. oil. Initial studies were carried out at lab scale in order to determine the experimental conditions that could lead to a high yield of biodiesel from the alkaline...

Conversion of Inexpensive Oils Into Biodiesel Using ZnO Nanoparticle Catalyst

Nov 11, 2009

Shuli Yan

Biodiesel is a mixture of fatty acid esters which can be produced from vegetable oils or animal fats with methanol. Recently, many researchers focus on using waste or unrefined oils as feedstock to decrease the production cost of biodiesel. A two-step method was reported, which firstly esterified...

Evaluation of Reaction Conversion and Energy Consumption During Biodiesel Production Using a High Shear Mixer Pilot Scale Reactor

Nov 11, 2009

Sipho Ndlela

Biodiesel is a renewable fuel that has the potential to lower vehicle sulfur emissions when used directly or in a blended form, and can be synthesized from fat and oil sources. These sources include refined vegetable oil, crude vegetable oil, waste oil, and animal fat. The two main reaction routes...

Growth Kinetic Study of Chlorella Vulgaris

Nov 11, 2009

Jinsoo Kim

Algae are simple autotrophic organisms that produce complex organic compounds from simple inorganic molecules such as carbon dioxide using energy from light or inorganic chemical reactions. These complex organics include a substantial amount of triacylglycerol which can be readily converted into...

Diurnal Cycling of Triacylglycerides in a Chlorophyte Sp.: Implications for the Production of Algal Biofuels

Nov 11, 2009

Keith Cooksey

There is no doubt that crude oil will be depleted eventually. The concept of global warming is now well accepted. Given these twin constraints, it behooves us to find alternative fuels, especially liquid ones for transportation. Microalgae have the potential to both reduce increases in greenhouse...

Commercial-Scale Energy Crop Production: Establishing Switchgrass in Tennessee

Nov 9, 2009

Timothy Rials

With the advancement of cellulosic ethanol technologies in recent years, more emphasis is being placed on the production of a sustainable supply of biomass for commercial scale facilities. These facilities will require significant supplies of biomass that will, in the southeast, come from private...

Designing Sustainable Options for Bioenergy Crops

Nov 9, 2009

Virginia Dale

Currently, the complexity and scale dependency of land-use decisions and their impacts are not understood, defined, or described with adequate clarity to enable policy makers to develop strategies to ensure a sustainable bioenergy future with acceptable environmental and socioeconomic consequences...

Enzymatic Bioprocessing of Cellulose in N-Methyl Morpholine Oxide/Water

Nov 9, 2009

John Collier

To enzymatically convert biomass to biorefinery feedstock, biofuels, or hydrogen an environmentally friendly solvent or process is needed to disrupt the microstructure of lignocellulosics. In multi-stage processes, solvents are being used as pretreatments by dissolving cellulose and precipitation...

Fuels from Thermoconversion of Biomass and Coal - Transportation Fuels from Coal and Biomass: Review of an NRC Report

Nov 8, 2009

James Katzer

The volatility of oil prices, the large proportion of oil importation, and the massive contribution of greenhouse gases from the transportation sector motivates the United States to seek domestic sources of alternative transportation fuels with lower greenhouse emissions. The abundance of coal and...
