Chemical-looping combustion (CLC) is a novel and promising technology for power generation with inherent CO2 capture. Currently almost all the research has been focused on developing CLC based inter-connected fluidized bed reactors. A new rotating reactor concept for gas fueled CLC is proposed. In the reactor, a solid wheel rotates between the fuel and the air streams at the reactor inlet and exit. Two purging sectors are used to avoid the mixing between the fuel stream and the air stream. The rotating wheel consists of a large number of channels with copper oxide coated on the inner surface of the channels. The support material is boron nitride which has high specific heat and thermal conductivity. Gas flows through the reactor at elevated pressure and it is heated from 823K to 1245K by fuel combustion. The rotary reactor design for a thermal capacity of 1MW has been performed using a simplified model that was developed to predict the performances of the reactor. Preliminary analysis shows that both the fuel conversion efficiency and the carbon separation efficiency are close to unity. The wheel temperature fluctuation is small. There is great potential for further improvement of the construction and operating conditions, which will be followed up in the future.

A number of CO2 capture-enabled power generation technologies have been proposed to address the negative environmental impact of CO2 emission. An important barrier to adopting these technologies is the associated energy and economic penalties. Chemical-looping (CLC) is an oxycombustion technology that can significantly lower such penalties, utilizing a redox process to eliminate the need for an air separation unit and enable better energy integration. Conventional CLC employs two separate reactors, with metal oxide particles circulating pneumatically in-between, leading to significant irreversibility associated with reactor temperature difference. A rotary reactor, on the other hand, maintains near-thermal equilibrium between the two stages by thermally coupling channels undergoing oxidation and reduction. In this thesis, a multiscale analysis for assessing the integration of the rotary CLC reactor technology in power generation systems is presented. This approach employs a sequence of models that successively increase the resolution of the rotary reactor representation, ranging from interacting thermal reservoirs to higher fidelity quasi-steady state models, in order to assess the efficiency potential and perform a robust optimization of the integrated system. Analytical thermodynamic availability and ideal cycles are used to demonstrate the positive impact of reactor thermal coupling on system efficiency. Next, detailed process flow-sheet models in which the rotary reactor is modeled as a set of interacting equilibrium reactors are used to validate the analytical model results, identify best cycle configurations and perform preliminary parametric analysis for between the reactor and the system while maintaining computational efficiency, an intermediate fidelity model is developed, retaining finite rate surface kinetics and internal heat transfer within the reactor. This model is integrated with a detailed system model and used for optimization, parametric analysis and characterization of the relative techno-economic performance of different oxygen carrier options for thermal plants integrated with the rotary CLC reactor. Results show that thermal coupling in the redox process increases the efficiency by up to 2% points for combined, recuperative and hybrid cycles. The studies also show that the thermal efficiency is a function of the reactor purge steam demand, which depends on the reactivity of the oxygen carrier. While purge steam constitutes a monotonic parasitic loss for the combined cycle, for recuperative and hybrid cycles, it raises the efficiency as long as the steam demand is less than a threshold value. This relationship between reactivity and system efficiency provides a useful selection criteria for the oxygen carrier material. Optimization results based on efficiency and levelized cost of electricity (LCOE) identify nickel-based oxygen carriers as the most suitable for the rotary reactor because its high reactivity ensures low steam demand and reactor cost. Compared to nickel, maximum efficiency and minimum LCOE are respectively 7% lower and 40% higher for a copper-based system; iron-based systems have 4% higher maximum efficiency and 7% higher minimum LCOE. This study also showed that optimal efficiency generally has an inverse profile to that for the optimized LCOE.

The design process for an experimental platform measuring reaction kinetics in a chemical looping combustion (CLC) process is documented and justified. To enable an experiment designed to characterize the reaction kinetics of the reduction/oxidation cycle in a rotary channeled oxygen carrier, a platform was designed to deliver controlled conditions of temperature and gas flow around a central disc of oxygen-carrier material and determine the rates of oxidation and reduction using real-time gas analysis (RTGA). In order to deliver precise and accurate results, it was necessary to identify and either minimize or compensate for interfering factors such as gas turbulence, temperature fluctuation, and flow equipment response time delays. This paper serves as a progress report on the experimental reactor; the overall design process is discussed, including equipment selection, reactor design, electronics and control hardware setup, and software interface design, and the current state of the reactor is discussed, including an assessment of the current capabilities and drawbacks of the system, future work, and potential methods for improvement.

The Program Manager for Assembled Chemical Weapons Assessment (PMACWA) of the Department of Defense (DOD) requested the National Research Council (NRC) to assess the engineering design studies (EDSs) developed by Parsons/Honeywell and General Atomics for a chemical demilitarization facility to completely dispose of the assembled chemical weapons at the Pueblo Chemical Depot in Pueblo, Colorado. To accomplish the task, the NRC formed the Committee on Review and Evaluation of Alternative Technologies for Demilitarization of Assembled Chemical Weapons: Phase II (ACW II Committee). This report presents the results of the committee's scientific and technical assessment, which will assist the Office of the Secretary of Defense in selecting the technology package for destroying the chemical munitions at Pueblo. The committee evaluated the engineering design packages proposed by the technology providers and the associated experimental studies that were performed to validate unproven unit operations. A significant part of the testing program involved expanding the technology base for the hydrolysis of energetic materials associated with assembled weapons. This process was a concern expressed by the Committee on Review and Evaluation of Alternative Technologies for Demilitarization of Assembled Chemical Weapons (ACW I Committee) in its original report in 1999 (NRC, 1999). The present study took place as the experimental studies were in progress. In some cases, tests for some of the supporting unit operations were not completed in time for the committee to incorporate results into its evaluation. In those cases, the committee identified and discussed potential problem areas in these operations. Based on its expertise and its aggressive data-gathering activities, the committee was able to conduct a comprehensive review of the test data that had been completed for the overall system design. This report summarizes the study.

Biomass has received considerable attention as a sustainable feedstock that can replace diminishing fossil fuels for the production of energy and chemicals. At the present moment in the oil refining, petrochemical and chemical industry, after fractionation of crude oil, various fractions are upgraded either to fuels or functionalized to produce intermediates and specialty chemicals. An analogous concept of biorefining is based on the utilization of biomass as a renewable source of carbon, which could be transformed to valuable chemicals. Although various aspects of biomass transformations are frequently discussed in the literature, chemical engineering aspects of such transformations are commonly not considered. The aim of the present book is to fill this void. Updates and informs the reader on the latest research findings using original reviews Written by leading industry experts and scholars Reviews and analyzes developments in the field
