NICKEL CATALYST SUPPORTED ON POROUS YTTRIA STABILIZED ZIRCONIA, PREPARATION METHOD THEREOF AND METHOD FOR PRODUCING HYDROGEN BY AUTOTHERMAL REFORMING OF ETHANOL USING SAID CATALYST

摘要

PURPOSE: A nickel catalyst supported on porous yttria stabilized zirconia, a preparation method thereof, and a method for producing hydrogen through autothermal reforming are provided to obtain excellent carrier properties by modifying unstable zirconia into a stable porous material having a wide surface area and to solve deactivation problems due to sintering and carbon deposition. CONSTITUTION: A method for preparing a nickel catalyst supported on porous yttria stabilized zirconia comprises the following steps: manufacturing an yttrium precursor mixture solution by dissolving a surfactant, which is a templated material, and dispersing 0.01-1 mol of the yttrium precursor on a mixture comprising micelles based on 1 mole of a zirconium precursor; mixing a zirconium precursor solution with the yttrium precursor mixture solution and gelating the mixture by hydrating and condensing the zirconium precursor and the yttrium precursor; hydrothermally synthesizing the gelled material and fermenting the gelled material; manufacturing the porous yttria stabilized zirconia by removing the templated material; dipping the nickel by mixing the porous yttria stabilized zirconia carrier and a nickel precursor solution to dip 1-50 parts by weight of nickel on 100 parts by weight of the carrier; and drying and thermally processing the dipped catalyst.
