Studies of calcination and reduction of nickel-alumina catalysts for hydrogenation of fats.

The effect of the calcination and reduction conditions on the degree of red uction of nickel-alumina catalyst precursor for fat hydrogenation was teste d. Occurrence of calcination and reduction process for selected values of h ydrogen flow rate is presented as the dependence of water vapor concentrati on and degree of nickel oxide reduction upon temperature and time. It has b een shown that the conditions of both the calcination and reduction process es had substantial impact to the precursor reduction.
