Abstract: PURPOSE: A catalyst for modifying carbon dioxide and a method for preparing the same are provided to improve carbon resistance and to block catalyst inactivation. CONSTITUTION: A catalyst for modifying carbon dioxide is denoted by chemical formula, Ni-La-Al_2O_3. In chemical formula, Ni content is 5-20 weight% and the ratio of Na/Al 0.04-0.06. NiO particles are uniformly distributed between La-Al_2O_3. The catalyst is prepared by mixing La, Al, and Ni with precursor; a step of adding an solution to generate precipitate; and a step of drying and plasticizing the precipitate at 400-800°C for 5-8 hours by coprecipitation.

Abstract: PURPOSE: A manufacturing method of synthetic gas including cobalt based catalyst for methane and carbon dioxide reformation and carbon monoxide using the same and hydrogen is provided to have excellent reaction activity than existing nickel reformation catalyst, and to have improved life span by the low-temperature reaction. CONSTITUTION: The cobalt based catalyst for methane and carbon dioxide reformation is marked as a(X)-b(Co)-c(Y)/Z. In the chemical formula X is Pt, Pd, Rh, Ir,or Ru and Y is Zr or La and the carrier Z is SiO2 or Al2O3. On the carrier Z 100 weight part, a is 0.1 ~ 10.0, b is 5.0 ~ 30.0, and c is 1.0 ~ 30.0 parts by weight. The manufacturing method of the synthetic gas including the carbon monoxide and hydrogen is manufacturing the synthetic gas under the exhaust gas of the molar ratio of 1 : 0.5 ~ 2.0 of the CO / H2 by using the catalyst. The manufacture is enforced under the temperature of 600 ~ 800 °C, and the pressure of 0.01 ~ 1 MPa and space velocity condition of 500 ~ 100,000 ml / g cat·hr.
