Biofuels (Energy)

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...

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,...

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.

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...

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...

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...

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...

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...

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...
