- A cobalt catalyst supported on mesoporous calcium oxide-alumina xerogel support preparation method thereof and production method of hydrogen gas by steam reforming of ethanol using said catalyst

摘要

The present invention relates to a cobalt catalyst supported on a mesoporous calcium oxide-alumina gel (Xerogel) carrier, a process for preparing the same, and a process for producing hydrogen gas by steam reforming reaction of ethanol using the catalyst, A calcium oxide-alumina gel which is used in the production of hydrogen gas by the steam reforming reaction of ethanol and has a pore range of 2 to 50 nm and a calcium / aluminum atomic ratio in the range of 0.01 to 2, A cobalt catalyst supported on a medium porous calcium oxide-alumina gel carrier, wherein cobalt is supported in an amount of from 5 to 60% by weight based on 100 parts by weight of cobalt, a process for preparing the same, The present invention relates to a method for producing hydrogen gas by a reaction. According to the present invention, incorporation of calcium oxide into a cobalt / alumina catalyst not only improves the degree of dispersion of cobalt but also improves the stability of the catalyst by decreasing ethylene selectivity due to reduction of the acid number of alumina. The hydrogen gas of high purity can be efficiently produced.
