NICKEL REFORMING CATALYST FOR PREPARING SYNTHESIS GAS AND METHOD FOR PREPARING SYNTHESIS GAS FROM NATURAL GAS BY STEAM REFORMING
摘要
PURPOSE: According to steam reforming reaction using nickel reforming catalyst(Ni/Ce-ZrO2) where synthesis gas containing hydrogen as primary ingredient is prepared from natural gas comprising primary methane, the present nickel reforming catalyst(Ni/Ce-ZrO2) has superior methane conversion rate when used as catalyst for steam reforming. CONSTITUTION: The nickel reforming catalyst(Ni/Ce-ZrO2) for preparing synthesis gas is characterized in that zirconia coated with cerium 0.01-1.0mol.% is further supported with nickel 5-20wt.%. The method for preparing synthesis gas from natural gas by steam reforming is performed by steam reforming reaction under operation conditions that reaction a mole ratio of methane and steam is 1:2-7, a reaction temperature is 600 to 1000deg.C, a reaction pressure is 0.5-30atm and a space velocity is 1000-500000cc.
