The invention belongs to the technical field of a catalyst, and particularly relates to a preparation method of a
methane reforming reaction catalyst. The method comprises the following steps of (1) performing
raw material mixing to obtain a mixed
reagent; (2) uniformly mixing the mixed
reagent obtained in the step (1) with expanded
perlite; performing ball milling for 30 to 50h at the temperatureof 60 to 90 DEG C to obtain black
slurry; (3) performing sublimation
drying and crushing on the black
slurry obtained in the step (2) at low temperature and low pressure; then, introducing
ammonia gas at the temperature being 700 to 900 DEG C; performing
roasting for 4 to 8h; performing cooling to obtain light-weight
solid materials; (4) dissolving light-weight
solid materials obtained in the step (3) into water being 2 to 6 times of the
mass of the light-weight
solid materials; then, using an
ultraviolet light source for
radiation treatment; performing
drying; obtaining a finished product. The catalyst prepared by the method has the advantages that the
reaction temperature of the
methane and
carbon dioxide is reduced; in addition, the surface active sites and the pore structures of the catalyst are stable, so that the service life of the catalyst is long.
