Abstract
The application discloses a carbon deposition resistant nickel-based catalyst for a dry reforming reaction of methane and a preparation method of the catalyst, and the preparation method comprises the following steps: step one, mixing lanthanum nitrate hexahydrate, aluminum nitrate nonahydrate and glycine, and adding deionized water, and stirring until a transparent solution is formed; step two, evaporating the transparent solution to form a gel; step three, drying the gel, igniting, and calcining to obtain a fluffy powder; grinding the powder to obtain a modified alumina carrier; step four, loading nickel on the modified alumina carrier by taking nickel nitrate hexahydrate as a precursor, so as to obtain the carbon deposition resistant nickel-based catalyst for the dry reforming reaction of methane.
