Pennycress-Derived Jet Fuel and Diesel LCA: Sustainable Advanced Biofuels

Oct 17, 2011

Jiqing Fan

Pennycress-derived jet fuel and diesel show promise as emerging biofuels that can help reduce dependence on petroleum imports, lower the trade deficit, and most importantly, lower greenhouse gas (GHG) emissions. Pennycress is a prolific seed producer with yields of more than 2000 pounds of per acre...

Steam Reforming of Ethanol-Phenol Mixture As a Model for Biomass Tar

Oct 17, 2011

Guido Busca

Introduction Hydrogen is produced by biomasses through a variety of pyrolysis and gasification processes. Most of these processes are hampered by the coproduction of tars, a mixture of heavy compounds that may result in fouling of heat exchangers and reactors. A steam reforming step is needed to...

Kinetics Study of Calcium Carbonate Decomposition At High CO2 Environment

Oct 17, 2011

Jian Zhang, Yong Min

With the concerns of “global warming”, CO2 sequestration from cement industry are becoming significant important for the “green processing” for the environments. This is because the cement processing released about 36% of CO2 comparing to the 12% from regular coal-power plant. CaO/CaCO3, a major...

The Horizontal Ribbon Growth of Solar Silicon Crystals: Process Analysis, Stability, and Control

Oct 17, 2011

Parthiv Daggolu

Present-day photovoltaic technology is predominantly based on the fabrication of solar cells from silicon. The cost and efficiency of silicon-based solar cells depend primarily on the growth rate and degree of single-crystallinity attained by the growth process. Traditional silicon crystal growth...

Milking Lipids From Green Alga: Feasibility of Using Biocompatible Solvents to Extract Lipids From Living Cells

Oct 17, 2011

Ryan Coiner

A key hurdle in realizing commercial-scale production of biodiesel from cultured algae is efficient harvesting/dewatering of algal cells. In order to produce a gallon of biodiesel from algae, thousands of gallons of water must be processed, even when algal biomass is grown in relatively...

An Integrated Framework for Design of Sustainable Chemical Process Based On Life Cycle Assessment

Oct 17, 2011

Masahiko Hirao

In this work, we propose a supporting framework for the design of chemical process integrating computer-aided process engineering (CAPE) and life cycle assessment (LCA) tools. LCA has been a useful tool for quantifying the environmental impacts from existing product life cycle and its application...

Implementation of QbD Paradigm In Sterile Dosage Form Packaging – Some Practical Considerations

Oct 16, 2011

Dr. Hemant N. Joshi

Out of all the pharmaceutical dosage forms, the Quality Target Product Profile (QTPP) for the sterile dosage form is the strictest for obvious reasons. One has to pay attention to the critical quality attributes (CQA) to a great extent. This presentation is focused only on the packaging of sterile...

Planar Biomimetic Aquaporin-Incorporated Triblock Copolymer Membranes On Porous Solid Supports

Oct 16, 2011

Phuoc H.H. Duong

The aim of the present study was to demonstrate the preparation and characterization of planar biomimetic bacterial water-channel protein Aquaporin Z (AQPZ)-incorporated polymer membranes on porous solid substrates by vesicle spreading for water treatment. AQPZ -incorporated polymer vesicles were...

Rule of Thumb for Reactor Design and Process Conditions for Supercritical Water Gasification of Wet Biomass

Oct 16, 2011

Yukihiko Matsumura

The Rule of thumb for reactor design and process conditions for supercritical water gasification of wet biomass is introduced. The important aspects includes heat transfer and heating rate, reaction rate, plugging, gas composition, inorganic element behavior, and heat of reaction. The know-hows...
