  2. Dissolution of Different Commercial Aspirin Tablets Using a Novel Off-Center Paddle Impeller (OPI) Dissolution Testing System

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    Dissolution testing is routinely conducted in the pharmaceutical industry to provide in vitro drug release information for quality control purposes. The most common dissolution testing system for solid dosage forms is the United States Pharmacopeia (USP) Dissolution Testing Apparatus 2. In this...

  3. An Overview of Chemical-Looping Reduction in Fixed-Bed and Fluidized Bed Reactors Focused On Oxygen Carrier Utilization and Reactor Efficiency

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    Chemical-looping combustion is a method for the oxidation of hydrocarbons with in-situ CO 2 capture. The basic concept of the process involves two interconnected reactors, a Reducer and an Oxidizer, with an oxygen carrier (OC) ¨C a metal/metal oxide circulating between the two. The main principle...

  4. Effect of Pore and Particle Size of Oxygen Carriers On Chemical-Looping Combustion and Reforming

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    Effect of pore and particle size of oxygen carriers on chemical-looping combustion and reforming Lu Han , Zhiquan Zhou, George M. Bollas Abstract Chemical-looping combustion (CLC) addresses the current CO 2 problem caused by fossil fuel utilization for power production. The main advantage of CLC...

  5. Li4SiO4-Based Novel Solid Fluidizable Sorbent for CO2 Capture:

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    This study investigates the cyclic use of several sorbents for CO2 capture and comparative study of thermodynamic analysis to predict sorbent regeneration conditions and thermal levels where sorbent kinetics change from CO2 absorption to CO2 desorption. It is expected cycling processes with CO2...

  6. A Kinetic Interpretation of Autohydrolysis of Mixed Southern Hardwood Chips in a Pilot Scale Reactor

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    Woody biomass is an important sustainable carrier of chemicals , materials and energy for humanity. Selectively extracting five carbon sugars from woody biomass is an intelligent choice for bioconversion of woody biomass. Mixed southern hardwood chips were loaded in a pilot-scale reactor of 1.84 m3...

  7. Hierarchical Pore Structure Zeolites for the Catalytic Upgrading of Tars

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    Hierarchical pore structure zeolites for the catalytic upgrading of tars Ameya Akkalkotkar, Shoucheng Du, George M. Bollas, Julia Valla Introduction Thermochemical conversion of biomass via gasification has attracted increasing scientific interest lately. However, one of the most important...

  8. Modeling of CO2 Capture Using Microalgae

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    In order to model the growth of microalgae in a open-pond reactor , a 1000L system has been built and operated under realistic outdoor conditions. Environmental data (light intensity , temperature , pH) were captured with a datalogger and the growth was measured. A phenomenological mathematical...

  9. Production and Characterization of Straight-Run Thermal Deoxygenation (TDO) Fuels

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    Thermal DeOxygenation (TDO) refers to a simple , non-catalytic , process which produces highly deoxygenated crude oils from levulinic and formic acids formed by acid hydrolysis of biomass feedstocks. The TDO reaction is a single-step decomposition reaction which converts the neutralized acids to...

  10. Laser-Activated Carbon Nanoparticle Cellular Damage and Prevention

    ChemE On Demand Presentation (AIChE Annual Meeting, 2013)

    The cell membrane is a challenging barrier to cross because of its structure and composition. Endocytotic processes can be inefficient, especially for molecules that have therapeutic value such as siRNA , plasmids, etc. So it is a challenging task to come up with a method that can address the issue...
