Please see the notice below: On Wednesday May 22nd, the electricity will be shut down to the Potter building between 9:15pm and 1:15am on May 23rd. There will be some limited electricity for critical equipment (ultra-low temperature freezers etc), but not for anything else during this time. You will need to plan your work accordingly if you have experiments that will run overnight. We need your help in making sure that you shut down all electrically powered equipment before leaving on May 22nd. Critical equipment (HPLC, GC, etc) should also be unplugged during the electrical shutdown. Linda and Rick will coordinate these efforts, but everyone must do their part. If you have any questions, please ask me. Thank you, Nate -------------------------------------------- Nathan Mosier Associate Professor Department of Ag. and Bio.

Seminar Reminder - Friday April 26th
by Mosier, Nathan S 23 Apr '13

23 Apr '13

Reminder! The last seminar of the semester: April 12th All LORRE graduate students are expected to attend. Catalysts for Producing HMF from Cellulosic Biomass Barron Hewetson Removing carbohydrates from renewable plant material is the most challenging process in the production of platform chemicals, such as 5hydroxymethylfurfural (HMF), from the structurally intertwined polysaccharides of lignocellulosic plant biomass. Lignocellulosic material is composed of three main components: lignin, cellulose and hemicellulose. Plant biomass fractionation is a vital step in the processing of any lignocellulose into value-added products and is often a result of a pretreatment process. Lignocellulosic material must undergo a pretreatment process to enhance the reactivity of cellulose. The hydrolysis of cellulose is important in fractionation because it liberates glucose, which can be converted to a wide range of fuels and chemicals of value. My research focuses on a cellulose solvent (85% w/w phosphoric acid) to remove and then recover cellulose from several plant biomass sources (corn stover, switchgrass, and poplar) and purified cellulose (Avicel). The resultant biomass is subjected to a conversion process where maleic acid hydrolyzes the cellulose to glucose, AlCl3 isomerizes the resultant glucose to fructose, and both acid catalysts dehydrate the fructose to HMF in a single reactor. The HMF is continuously extracted into 2-methyltetrahydrofuran (MTHF) in a 2-phase reactor. The results confirm that yields of HMF can be substantially increased by cellulose dissolution followed by a second hydrolysis using bi-functional Lewis/Bronsted acid catalysts to hydrolyze regenerated amorphous cellulose and dehydrate the resulting monosaccharides.

Seminar Reminder - Friday April 12th
by Mosier, Nathan S 09 Apr '13

09 Apr '13

Reminder! Next Seminar: April 12th All LORRE graduate students are expected to attend. Solvent Selection and Recovery for Liquid-Liquid Extraction of Acetic Acid and Water Mahdieh Aghazadeh The removal of acetic acid from biomass hydrolysate is crucial to increase the yield of ethanol during fermentation. The acetic acid released during hydrolysis works to slow down the fermentation and significantly decrease the yield of ethanol. The overall goal of this project is to explore the removal of acetic acid from the hydrolysate using liquid-liquid extraction (LLE). The use of liquid-liquid extraction to remove acetic acid from water is traditionally performed with ethyl acetate. This step is then coupled to a distillation tower to purify the acetic acid from the solvent stream. The drawback to this method is the operational expense of the distillation column. The use of a membrane for separation is more cost effective and possibly even more efficient. The work performed for this study was to use Aspen Plus to determine a reasonable solvent to recover Acetic Acid from water. The aim was to identify a solvent that has great affinity to acetic acid and low solubility in water, and also required the least extreme operating conditions as far as temperature and pH were concerned. Once the solvent was identified, the next step was to determine the best type of membrane. Based on the molecular size of the solvent and acetic acid and also their hydrophobicity differences, molecular sieve or zeolite-based membrane systems were tested.

Seminar Announcement WHISTLER CENTER FOR CARBOHYDRATE RESEARCH DEPARTMENT OF FOOD SCIENCE sponsored lecture: "Plants to Plastics" Atanu Biswas Lead Scientist, NCAUR/USDA Peoria, IL Friday, March 29, 2013 1:30 p.m. Morgan Conference Room FS2187 NLSN (Food Science Building) As we are located in the Corn Belt, our goal has always been to enhance the utilization of corn. Dr. Biswas will talk about research at NCAUR dealing with expanded uses of the components of corn, such as starch, protein, fiber, and oil. Past and ongoing research work includes chemical and enzymatic modifications of renewable resources to produce new biobased materials and value-added products. A particular emphasis is to develop new, green synthetic methodologies through microwave, ionic liquid, and solvent-less processes. Atanu Biswas is a Lead Scientist with USDA at Peoria, IL. He received his Ph.D. from the University of Notre Dame. After a postdoctoral stay at University of Virginia, Charlottesville, VA he went to Hercules Incorporated where he worked for 14 years and had 6 patents and one paper. Ten years ago he joined USDA where he has published over 60 papers and one patent thus far. His research deals with green chemistry, polysaccharides, and vegetable oils. A recent focus has been the chemical and enzymatic modifications of renewable resources to produce value-added products. His research emphasizes creativity, collaboration and team work in developing new bio-based materials from starches and proteins using various chemical, physical and biochemical processes to create new market opportunities for agricultural products, and for usage in formulations of adhesives, bio-based plastics, coatings, films, hydrogels, and absorbents.
