Development of a palladium based membrane reactor system for production of ultra-pure hydrogen from liquefied petroleum gas

Kula, Lungelwa Ethel January 2017 (has links)
Thesis (MTech (Chemical Engineering))--Cape Peninsula University of Technology, 2017. / Hydrogen is widely regarded as the clean energy carrier for future use in both transportation and electricity sectors. It has become an important new focus as an alternative fuel for cleaner energy technologies especially in the Polymer Exchange Membranes (PEM) fuel cells. However, specific technical and marketing demands must be met by a fuel processor for ultra-pure hydrogen production and at a very competitive cost. Liquid Petroleum gas (LPG) is seen as a potential source for low cost hydrogen production due to its relatively high energy density, easy storage and well-established infrastructure for fuel. There is a growing interest in the use of membrane in reaction engineering with the selective separation of the products from the reaction mixture provided opportunities to achieve higher conversion. Membrane separation technologies have potential to reduce operating costs, minimise unit operations and lower energy consumption. The overall goal of this project is to investigate the engineering feasibility associated performance of employing a palladium or palladium alloy membrane reactor for the production of ultra-pure hydrogen from the products of a liquefied petroleum gas (LPG) pre-reformer in determining the optimal process conditions for the production of high purity hydrogen from the LPG feedstock and evaluating of the performance of a Pd-based membrane in relation to maximizing the yield of hydrogen from the feedstock as well as minimizing the CO content of the reformate.

Carbon Nanotube/Microwave Interactions and Applications to Hydrogen Fuel Cells.

Imholt, Timothy James 05 1900 (has links)
One of the leading problems that will be carried into the 21st century is that of alternative fuels to get our planet away from the consumption of fossil fuels. There has been a growing interest in the use of nanotechnology to somehow aid in this progression. There are several unanswered questions in how to do this. It is known that carbon nanotubes will store hydrogen but it is unclear how to increase that storage capacity and how to remove this hydrogen fuel once stored. This document offers some answers to these questions. It is possible to implant more hydrogen in a nanotube sample using a technique of ion implantation at energy levels ~50keV and below. This, accompanied with the rapid removal of that stored hydrogen through the application of a microwave field, proves to be one promising avenue to solve these two unanswered questions.
