MESOPOROUS NI-ALUMINA COMPOSITE CATALYST PREPARED USING ANIONIC SURFACTANT, AND METHOD FOR HYDROGEN PRODUCTION BY STEAM REFORMING OF LIQUEFIED NATURAL GAS USING SAID CATALYST

摘要

PURPOSE: A preparing method of a meso-porous nickel-alumina composite catalyst is provided to obtain the meso-porous nickel-alumina composite catalyst with a wide surface area and active surface area. CONSTITUTION: A preparing method of a meso-porous nickel-alumina composite catalyst comprises the following steps: forming a micelle by inserting an anionic surfactant to an alcohol solution and stirring; stirring the alcohol solution after inserting an aluminum precursor and dispersing; forming a composite consisting of the aluminum precursor and the micelle by mixing the dispersed mixture and the micelle and stirring; inserting a nickel precursor to the alcohol solution after melting the precursor to distilled water; mixing the nickel precursor mixture and the nickel precursor mixture and hydrating; condensing the mixture after a hydrothermal reaction; centrifugal separating and washing the outcome using the distilled water or the alcohol solution; and drying and heat treating the outcome.
