Abstract
The present invention relates to a nickel-based catalyst using hydrotalcite-like precursor and a steam reforming reaction by using the catalyst, and particularly to a nickel-based catalyst prepared by dispersing nickel uniformly onto the inner part and the surface of the support through a substitution between the magnesium and the active nickel metal and optimizing the molar ratios of nickel, magnesium and aluminum in order to utilize nickel as an active metal and a hydrotalcite-like precursor consisting of aluminum and magnesium, which shows an increased specific surface area of the catalyst and surface area of the active nickel, and thus enables the production of hydrogen-rich gas in high yield during the steam reforming reaction of LPG with superior maintenance of catalytic activity for a long period of time due to the inhibition of carbon deposition.
