Cellulase Inhibition by Pretreatment-Released Biomass Degradation Products

Oct 18, 2011

G. Peter van Walsum

The influence of pretreatment chemistry and the severity of dilute acid pretreatment on the subsequent enzymatic hydrolysis of soluble oligomer-derived and insoluble crystalline cellulose using a commercial enzyme preparation (Novozymes) was investigated. A dilute acid pretreatment was performed on...

Preparation and Testing of Adsorbents for the Separation of Ionic Liquids From HMF

Oct 18, 2011

Yuxiang Rao

HMF is an important chemical product since it has the potential to be used as a feedstock to replace petroleum-derived aromatics for production of a range of specialty chemicals and plastics.In this work, we will demonstrate an economically-viable, ionic liquid catalytic process for conversion of...

New Catalytic Technology for Converting Heavy Oils Derived From Alberta Oil Sands Into Petrochemical Feedstock

Oct 18, 2011

Vasily Simanzhenkov

Oil sands operations in Alberta are poised to experience significant growth over the next number of years. Production of 1.31 million bbl/day of synthetic crude oil and bitumen blends from oil sands in 2008 is projected to increase to over 3 million bbl/day by 2018. This guarantees a large output...

A New Generation of Zirconia Supported Metal Oxide Catalysts for Esterification of Free Acid Feedstocks

Oct 18, 2011

Manhoe Kim

The acid catalyst promotes esterification by reacting the carboxylic group of the FFA with methanol to form methylesters and water. In this reaction mixture, the sulfuric acid is more miscible in the water product phase than the methanol phase leading to a pronounced water inhibition effect that...

Synthesis of Green Diesel Fuel From Fatty Acid Feedstocks Via Electrochemical Hofer-Moest Decarboxylation

Oct 18, 2011

Cody Wagner

Production of biodiesel by esterification or transesterification of long-chain fatty acids is a well known process, but the fuel product has characteristics making it not fully compatible with petroleum diesel engines. A better option is to convert fatty acid molecules to hydrocarbons by removing...

Nanoarchitectured Ni-ZrO2 Catalysts for Hydrogen Production From Steam Reforming of Ethanol

Oct 18, 2011

Jinlong Gong

Hydrogen has been considered as an important alternative energy vector and a bridge to a sustainable energy future. Production of hydrogen efficiently and economically from renewable sources, however, remains a challenge. Among diversified hydrogen production technologies, steam reforming of...

Stabilization of Hanford K-Basin Sludge by Dissolution of Uranium Metal with Carbonate / Peroxide Solution

Oct 18, 2011

Stuart T. Arm

The Hanford K Basins were used until the mid 1960s to store, under water, spent nuclear fuel from the site’s reactors before reprocessing to recover uranium and plutonium. A sludge consisting of cladding corrosion products, uranium, fission products and other debris accumulated on the floor of the...

Biological Conversion of Algefiber® (Seaweed Sludge) to Carboxylic Acids for Chemical Upgrading to Higher Alcohols Liquid Biofuel

Oct 18, 2011

Sampath A. Karunarathne

Concern about biofuel production from renewable resources has increased globally. Among different approaches to produce biofuels, the MixAlco ™ process is an innovative technology operating on the carboxylate platform, which converts any biodegradable material into mixed alcohol fuels through...

Insights Into Lactate Metabolism Through Multivariate Analysis of Cell Culture Bioprocess Data

Oct 18, 2011

Huong Le

Multivariate data analysis has recently emerged as a critical tool to gain fundamental understandings of process characteristics, and thus assisting the search for possible intervention means to improve process performance. The time dynamics of 150 process parameters acquired from 243 production...
