HYDROGEN PRODUCTION METHOD BY DIRECT DECOMPOSITION OF NATURAL GAS AND LPG

摘要

A nickel-iron catalyst on gamma-aluminum oxide which is prepared by means of a multi- step adsorption approach in a hydrogen production method by direct decomposition of natural gas and LPG is used. Aqueous solutions of nickel and iron nitrate salts are adsorbed together on the gamma-aluminum surface in preparing the catalyst used in this method, wherein the weight ratio of nickel and iron on the catalyst surface is 1 :1 and their total weight is 20-40% by weight. The temperature of this method varies between 550°C to 650°C.
