Iron based catalysts for production of carbon and hydrogen from decomposition of methane
Abstract
The invention provides a calcined Fex—Aly—Oz based catalyst for the decomposition of hydrocarbons such as methane to produce hydrogen and carbon. The catalyst comprises iron oxide mixed with aluminum oxide and calcined at temperatures above 1100° C., where Fex—Aly—Oz is a chemical composition with x>0.1, y>0.1, z≥0 and 02 and carbon. In an embodiment, carbon is separated from the catalyst and the catalyst is reused for continuous methane decomposition to produce H2.
