400 u00b0 c for three hours before mixed with 1 5 g graphite a catalyst is prepared according to the invention by the following procedure 55 g aluminum nitrate is dissolved in 180 ml d i water 34 g cu nitrate solution 15 5 and 20 g zn nitrate solution 15 5 along with the above aluminum nitrate solution are added into 962 g ferrous nitrate solution 9 5 the mixed solution and 300 ml naoh solution 25 are simultaneously added into a precipitation tank with stirring over a 40 minute period the temperature is then increased to 65 u00b0 c and held for five hours the resulting suspension is filtered and washed four times with d i water followed by drying at 110 u00b0 c for four hours the dried powder is calcined at 400 u00b0 c for three hours before mixed with 4 5 g graphite the mixed powders are tabbed a catalyst is prepared according to the invention by essentially the same procedure as in example 6 except 82 5 g aluminum nitrate and no zn nitrate solution are used a catalyst is prepared according to the invention by essentially the same procedure as in example 6 except 51 g cu nitrate solution 15 5 and no zn nitrate solution are used the catalyst is preferably used in a typical water gas shift process typical reaction conditions for the process would include inlet temperatures equal to or greater than 200 u00b0 c feed pressure equal to or greater than 1 atm and a.
