The Catalytic Gasification of Waste Polymers: Determining the Kinetics of the Sabatier Reaction

This research focuses on advancing the knowledge of a catalytic gasification process as a potential in-situ resource utilization and waste management alternative. This research has significance in a variety of engineering applications, but it is of particular relevance towards reducing landfill waste or as an in-situ resource generation system for space exploration beyond Low Earth Orbit (LEO). This process evolves through a reaction mechanism consisting on two liquid-phase oxidation reactions of long-chain polymers, complemented by two gas-phase reactions. This project focusses on one of the gas phase reactions: one of the main fuel producing reactions, the Sabatier (also referred to as “methanation”) reaction. The primary focus of this project is to analyze experimental data collected for this reaction, and to determine the kinetic parameters of the Sabatier reaction. The research is an outgrowth to previous kinetic determinations available for the reaction. Indeed, the data used to perform the kinetic analysis was originally collected by Lunde and Kester in the 1970s (Ind. Eng. Chem., Process Des. Dev., Vol. 13, No. 1, pp. 27-32, 1974). The kinetic analysis presented here is based on fundamental reactor design equations and was accomplished using numerical techniques not readily available at the time of Lunde and Kester\u27s analysis. The experimental data was split into two sets of data: one set used for parameter estimation, and second set to be used for validation purposes. Comparison with the original approach followed by Lunde and Kester is also provided.https://engagedscholarship.csuohio.edu/u_poster_2015/1045/thumbnail.jp

Experimental Analysis of Catalytic Gasification of Polyethylene

Over the last century there has been a global interest in reducing/recycling waste material as well as creating energy from renewable and more eco-friendly sources. Catalytic gasification is one effective method that can promote low-temperature conversion of solid waste to energy, also referred to as “gasification”. The gas mixture produced by gasification of long-chain polymers using ruthenium (or platinum) catalysts consists of hydrogen, methane, carbon monoxide, carbon dioxide, and water. Product mixtures of gasification experiments were analyzed by Gas Chromatography (GC) and post-processed using statistical analysis. Using fundamental reactor design equations along with stoichiometric calculations yielded the percent gasified as well as the reaction selectivity of the process. The solid residues containing ashes, char, ruthenium, and polyethylene unreacted were analyzed in a Differential Scanning Calorimetry (DSC) and a Scanning Electron Microscope (SEM) to identify its components. Quantification of the DSC spectra was used to correlate the thermal characterization of the residues with the unconverted (or non-gasified) after the reaction was quenched. Lastly, the SEM provided information on the microstructure of the residues, their atomic composition, and preliminary assessment of the possibility of catalyst recovery. These results are next to be used in formulating a kinetic mechanism for the liquid- phase oxidation, and thus complete a model of catalytic gasification amenable for scaling-up the process to continuous operation.https://engagedscholarship.csuohio.edu/u_poster_2015/1046/thumbnail.jp

Leak detection using cepstrum of cross-correlation of transient pressure wave signals

A new leak detection method is proposed here which is based on the cepstrum of the cross-correlation of the pressure signals from two transducers. Computational simulations of leaks with different properties, size, position and shape, in a straight pipe and a T-Junction network were studied. The proposed method was successful in estimating leakages and the pipeline features with a high precision. For the results with a straight pipe, this method is considerably more accurate than using the cross-correlation leak detection method or the cepstrum method alone. However, the results obtained by cepstrum and cepstrum of cross-correlation for the T-Junction case were quite accurate, while cepstrum alone showed a slightly better precision
