A method for preparing hydrogen is provided to produce the hydrogen efficiently through a steam reforming reaction of LNG(Liquefied Natural Gas), by using a metal catalyst supported on an alumina Xerogel carrier. At least one metal catalyst, which is selected from a group consisting of Pt, Au, Pd, Rh, La, Ce, Yb, Ni, Cu, Ag, Ru, Ir, Os, Co, V, Fe, Sn, Ca, and Mg, is supported on an alumina Xerogel carrier. The metal catalyst contains a weight percent of 1-50 wt%, based on 100 wt% of the alumina Xerogel carrier. Steam and LNG containing methane gas and ethane gas are flown at a space rate of 2,000-30,000 ml/h.g-catalyst, within the metal catalyst. Further, a mixing volume rate of the LNG/the steam is 1 to 10, and a mixing volume rate of the methane gas/the ethane gas is 9 to 99.9. |
