Providing the methods and apparatus for a sustainable process of producing hydrogen gas and elemental carbon with reduced CO2 emissions, utilizing a carbon based catalyst
Currently, hydrogen is used as the main fuel of the space program, and it is now rapidly expanding into new markets such as fuel cell driven automobiles and power generation. A key advantage of hydrogen is the high efficiency with which it is converted to electricity. Producing and storing hydrogen gas is a multi-billion dollar business. Thus, any advances in the production of hydrogen would yield a tremendous profit. The primary means of industrial hydrogen manufacturing are via oxidative reforming of hydrocarbons and water electrolysis. Unfortunately these methods suffer from several drawbacks: some are very energy intensive, while others make use of expensive metal catalysts which tend to deactivate due to carbon build up, and many produce CO2 and other air polluting gases.
Scientists at UCF have developed a new method for carbon-catalyzed production of hydrogen with reduced CO2 emission. This method uses hydrocarbon feedstocks such as natural gas, liquefied petroleum gas, biogas, and even sulfurous hydrocarbon fuels. The process utilizes carbon catalyst insitu produced from common, inexpensive materials such as methane; because the catalyst is made of carbon, the need for a catalyst regeneration step is removed. Since no oxidant (e.g., steam, oxygen) is involved in the process, CO2 emissions are eliminated or significantly reduced. The hydrogen gas collected from this method has a purity of 99.99 % by volume. The resulting carbon byproducts can potentially be used as a structural material.
