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...

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...

Biomimicry of the Fungal Consolidation of Biomass Pretreatment with Saccharification

Oct 18, 2011
Justin T. Kaffenberger
Efficient breakdown of ligno-cellulosic material prior to fermentation for bio-fuel production is a key step in optimizing bio-fuel production. Current industrial practice involves chemical pretreatment and acid or enzymatic saccharification to prepare ligno-cellulosic biomass for fermentation. The...

An Integrated Lipid-Based Platform for “Drop-In” Fuel Biorefinery

Oct 18, 2011
Shulin Chen
A major challenge in developing biorefinery is that the availability of biomass often limits the scale of the plant thus the feasibility of an operation. We proposed an integrated lipid-based platform as one technical option. According to this concept, different biomass resources will be first...

Fischer Tropsch Synthesis Via Biomass Derived Synthesis Gas

Oct 17, 2011
Syed Ali Gardezi
Due to the recent surge in energy costs and uncertainties in fuel prices, there is significant interest in seeking alternative sources of energy particularly from renewable such as biomass. Indirect liquefaction of biomass (via the thermo-chemical conversion to syngas followed by liquefaction via...

A Novel Method to Harvest Microalgae Via Fungal Pelletization

Oct 17, 2011
Jianguo Zhang
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...
