A nickel catalyst supported on phosphorus-containing mesoporous alumina xerogel support, preparation method thereof and production method of hydrogen gas by steam reforming of liquefied natural gas using said catalyst

摘要

present invention is a porous alumina, including medium controlled by a gel (Xerogel) carrier a supported nickel catalyst, a method of manufacturing the same and relates to a method of producing hydrogen gas by steam reforming of liquid natural gas (LNG) using the catalyst, more particularly, steam reforming of the liquefied natural gas (LNG) is used in the hydrogen gas produced by the reaction, and the porosity of 2 to 50 nm range, alumina being controlled by hyeongtaeyi the nickel with 0.1 to 50% by weight, based on the total catalyst weight supported on a carrier, including a gel, the carrier of a / the atomic ratio of aluminum in the range from 0.01 to 1 medium porosity alumina, including the control, characterized in that a nickel catalyst supported on a gel carrier, and a method of manufacturing the vapor of liquefied natural gas (LNG) using the catalyst It relates to a method of producing hydrogen gas by a reforming reaction. By the introduction of phosphorus according to the present invention can improve the adsorption property of the change in reaction to the interaction force between the nickel and the alumina support, the catalyst for the liquefaction of natural gas by applying the steam reforming reaction of (LNG) high purity hydrogen gas efficiently can be produced. ;
