A MESOPOROUS NICKEL-ALUMINA AEROGEL CATALYST, PREPARATION METHOD THEREOF AND PRODUCTION METHOD OF HYDROGEN GAS BY STEAM REFORMING OF LIQUEFIED NATURAL GAS (LNG) USING SAID CATALYST

摘要

PURPOSE: a kind of mesoporous nickel-alumina aerogel catalyst, manufacturing method, and reaction raising reproducibility of the steam modification based on liquefied natural gas for manufacturing hydrogen pass through and simplify synthesis path. ;CONSTITUTION: aluminum precursor is dissolved in the alcohol solvent of heat and obtains solution. Water, acid and alcohol and solvent portions hydration and transparent colloidal sol obtain. Nickel precursor, which is added colloidal sol by cooling and solves the hybrid collosol to obtain the mixing of notch aluminium oxide, to be cooled to room temperature. A kind of hydrate reaction and condensation reaction are realized using the mixed solution of the water and ethyl alcohol to obtain nickel-alumina hybrid gel. The hybrid gel aging room temperature. Old man's mixed gel uses supercritical carbon dioxide after drying. Dry mixed gel is heat-treated. ;The 2012 of copyright KIPO submissions
