Utilization Of Electrodeionization To Separate And Concentrate Cellobionic And Gluconic Acid, Andie Veeder
Chemical Engineering Undergraduate Honors Theses
Biofuel production is currently an expensive and inefficient process with many drawbacks. It is water and land intensive, competes with food production, and requires large energy inputs decreasing its relative sustainability. This paper explores the use of electrodeionization (EDI) to improve the biofuel process by separating and concentrating large, organic sugar acids that are important materials for the production of bioethanol. An EDI device was assembled for the purpose of separating and concentrating gluconic, cellobionic and lactobionic acid. Several trials were conducted and samples were analyzed to determine the success of this experiment. The results for the separation and concentration …

This paper presents an analysis of a filtration technique that uses ultrasound to aid the collection of small particles (tens of microns in diameter) from suspension. In this method, particles are retained within a porous mesh that is subjected to a resonant ultrasonic field, even though the pore size of the mesh is two orders of magnitude greater than the particle diameter. The role of acoustic forces in driving the retention phenomena has previously been studied on a micro-scale, which included modeling and experimental verification of particle motion and trapping near a single element of the mesh. Here, we build …
