Realizing the Potential of Advanced Biofuels

Oct 18, 2011
Thomas Foust
Advanced biofuels or drop-in fuels is the terminology used to refer to hydrocarbon fuels that are direct replacements or supplements for existing gasoline, diesel and jet fuels currently refined from conventional petroleum feedstocks. Drop-in fuels from biomass will need to meet all of the refinery...

The Role of Oxygen In the Stability of Biomass Pyrolysis Oils

Oct 18, 2011
Foster Agblevor
One of the major challenges in the conversion of biomass pyrolysis to high value products and fuels is the poor stability of the oils. Biomass pyrolysis oils have shown increases in viscosity during storage at ambient conditions and when heated above ambient temperature. The poor stability of the...

Pyrolytic Pathways to Advanced Biofuels

Oct 18, 2011
R. C. Brown
Pyrolysis is the thermal conversion of carbonaceous materials in the absence of molecular oxygen to liquids, solids and gases. In the most general sense, pyrolysis can occur in an inert or reducing atmosphere or within a solvent (including water); it can occur at atmospheric or elevated pressure;...

The Role of Acidic Catalyst Support On the Catalytic Upgrading of Bio-Oils

Oct 18, 2011
Sunya Boonyasuwat
Catalytic conversion of bio-oil vapor has attracted considerable interest as a promising pathway for upgrading. In this work, the reaction of anisole and guaiacol, phenolic model compounds commonly existing in bio-oils, were studied over an acidic silica-alumina catalyst and at varying space times...

Torrefaction of Switchgrass As a Pretreatment for Catalytic Upgrading of Pyrolysis

Oct 18, 2011
Lance Lobban
The objective of this work is to use thermal pretreatment to separate the complex bio-oil mixture to produce less complex vapor streams of products from 1. light oxygenates (small aldehydes, acids) , 2. furan derivatives, and 3. phenolics. The selective production of products by thermal treatment...

Comparison of Chemical and Biological Delignification of Cardboard

Oct 18, 2011
Estefania Isaza
Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...
