Gas Phase Reaction Kinetics Of Boron Fiber Production

Firat, Fatih 01 August 2004 (has links) (PDF)
In the production of boron fibers using CVD technique, boron deposition and dichloroborane formation reactions take place in a reactor. Boron deposition reaction occurs at the surface while formation of dichloroborane is the result of both gas phase and surface reactions. A CSTR type of reactor was designed and constructed from stainless steel to investigate the gas phase reaction kinetics and kinetic parameters of boron fibers produced from the reaction of boron trichloride and hydrogen gases in a CVD reactor. The gases were heated by passing through the two pipes which were located into the ceramic furnace and they were mixed in the CSTR. The effluent gas mixture of the reactor was quenched by passing through a heat exchanger. An FT-IR spectrophotometer was connected to the heat exchanger outlet stream to perform on-line chemical analysis of the effluent gas mixture. Experiments were carried out at atmospheric pressure and a reactor temperature range of 300-600 &ordm / C with different inlet reactant concentrations. The analysis of the FT-IR spectra indicated that the gas phase reaction and the surface reaction started at reactor temperatures above 170 &ordm / C and 500&ordm / C, respectively. It was concluded that reaction rate of the product increased with an increase in the inlet concentration of both reactants (BCl3 and H2) and with an increase in the reactor temperature. The gas phase reaction rate was expressed in terms of a th and b th orders with respect to the inlet concentrations of BCl3 and H2. The activation energy of the gas phase reaction, a and b were found to be 30.156 , 0.54 and 0.64, respectively. The correlation coefficient was 0.9969.

Van der Merwe, Andre 12 1900 (has links)
Thesis (MScEng) -- Stellenbosch University, 2003. / INTRODUCTION: The Medical Radiation department at iThemba LABS provides proton beam therapy facilities for irradiation of intracranial, head and neck lesions. Proton radiation treatment offers a number of advantages over alternative radiation therapy modal- ities. The most significant advantage is the ability to localize the dose to the lesion or target volume [16]. Lesions are located by means of medical imaging processes, such as Computer Tomography (CT) or Magnetic Resonance Imaging (MRI) scans. Patient treatment commences at the existing treatment facility of iThemba LABS. The patient positioning system that is currently in use at this facility was designed for only one horizontal beam delivery system and a limited number of treatment positions. The possibility of acquiring an additional beam delivery system and im- proving the utilization of the system resulted in plans to expand the current proton therapy capabilities. These plans resulted in the development of a new treatment vault, complete with a new patient positioning system. The new vault will cater for two beam delivery systems and expand current treatment positions.
