A method is provided for fabricating a catalyst carrier. At first, aluminum hydroxide is used for forming an alumina powder. The alumina powder is mixed with carbon nanotubes and a complex additive to be shaped into a cake. The cake is kneaded into a noodle-like shape to be hot-dried. Then, calcination is processed in a furnace under 1200 celsius degrees (&#xb0; C.) with air passed through. The crystal structure remains without phase change. A catalyst carrier of &#x3b1;-alumina having nano-scaled pores is formed. The catalyst carrier is a powdery material made into different three-dimensional forms. The catalyst carrier thus fabricated is suitable for generating hydrogen through methane reformation. The catalyst carrier has a methane conversion greater than 99 percents. The catalyst carrier will not be crumbled under 800&#xb0; C. for 4000 hours without carbon deposit.

Method of fabricating catalyst carrier for generating hydrogen through methane reformation

A reactor using honeycomb catalyst is provided for fuel reformation with high activity and heat stability. The reactor comprises a heating tube, a methane gas inlet, a three-way steam inlet and a hydrogen-rich gas outlet. The three-way steam inlet is near to the heating tube for providing heat required for reformation and to reduce power consumption. The heating tube is made of an inconel material so that the overall reaction may be carried out at high temperature. The heating tube is set with a honeycomb carrier of cordierite. The honeycomb carrier is pasted with carbon nanotube and heat-treated to increase internal surface area. The honeycomb carrier has a Pt/CeO/&#x3b1;-AlOcatalyst; is placed in the heating tube; and has honeycomb-pores channels parallel to a main axis of the heating tube.
