摘要

The present invention relates to a perovskite catalyst carried on an alumina support with a bimodal pore structure for a mixed reforming reaction and a manufacturing method thereof, capable of obtaining a high conversion rate of methane and carbon dioxide by carrying a metal catalyst with a perovskite structure of LaSrNiO_3 as an active ingredient on a Al_2O_3 support with a bimodal pore structure and inhibiting inactivation of a catalyst through sintering of nickel as an active ingredient, even when the catalyst is reacted at high temperatures.
