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...

Reducing Process Complexity for Cellulosic Ethanol

Oct 18, 2011
L.O. Ingram
Much of the process complexity and high capital costs associate with cellulosic ethanol (dilute acid hydrolysis as a pretreatment and enzymatic saccharification of cellulose) results from side products such as furfural, acetate, and soluble lignin compounds that inhibit the biocatalysts. Inhibitor...

Real Time Detection of Gaseous Metal Contaminants in Coal Flue and Fuel Gas

Mar 21, 2010
Erik C. Rupp
The Integrated Gasification Combined Cycle (IGCC) is a promising technology for the future use of coal to provide energy. During this process, many of the trace elements present in coal are volatilized, and remain in the gas phase through the gas turbine, only to be released in the flue gas. Trace...

Chemical Engineering Outside the Pipe: Industrial Ecology and Sustainability

Nov 7, 2010
Roland Clift
The 2010 Danckwerts lecture is concerned with explaining the emerging field of Industrial Ecology (IE) and why it represents a new and important area for application of the skills of the chemical engineer. Wikipedia, defines Industrial Ecology (IE) as “a ‘systems-based, multidisciplinary discourse...

Hybrid Membrane Absorption Process for Post Combustion CO2 Capture

Mar 23, 2010
S. James Zhou
Gas Technology Institute (GTI) and PoroGen Corporation are jointly developing a novel hybrid membrane – absorption process for pre- and post-combustion CO2 capture (Carbo-Lock™ process). The novel Carbo-Lock™ process combines advantageous features of both absorption and membrane processes to...

Nationwide Energy Supply Chain Analysis for Transportation Fuels

Oct 16, 2011
Josephine A. Elia
Hybrid energy processes are an attractive avenue towards a more sustainable energy future due to their flexibility in converting multiple types of inputs into a consistent range of products. For the transportation sector, Fischer-Tropsch synfuels can be generated from a diverse of feedstock inputs...

Mercury Control with Regenerative Activated Coke Technology

Mar 21, 2010
James Peters
Many issues face coal fired utilities with respect to environmental demands, some based on regulations and others based on local pressures. These include increasingly stringent control of criteria pollutants, anticipated federal and state requirements for mercury control, issues revolving around...

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...
