reaction products and unconverted feed gas was done by on line gas chromatography for test 12071 98 4 25 g of catalyst was used with 20 0 g of mineral oil for test 13464 01 which is a repeat run 6 0 g of catalyst was used with 20 3 g of oil the catalyst was reduced using a feed gas consisting of co h 2 co 2 n 2 in 2 1 1 4 0 5 96 molar proportions at a pressure of 7 8 atm during reduction the reactor temperature was slowly increased from room temperature to 240 u00b0 c the feed gas was then changed to a co h 2 co 2 n 2 mixture of 66 30 3 1 molar proportions and the reactor was pressurized to 59 atm the feed rate was adjusted to 5 000 std lit per kg of catalyst per hr and the temperature raised to 300 u00b0 c this condition was maintained for approximately 20 hr before analysis of the product stream was done table 1 shows the measured synthesis rates for the major products for the two runs on this catalyst table 1______________________________________ production rate g kg of catalyst hr test no test no 12071 98 13465 01______________________________________methanol 215 225ethanol 11 8 11 31 propanol 6 6 6 8isobutanol 15 1 13 41 butanol 3 1 2 82 methyl 1 butanol 7 3 6 51 pentanol 1 4 1 32 methyl 1 pentanol 4 9 4 51 hexanol 1 9 1 6dimethyl ether 2 8 1 9methyl acetate 3 9 3 8c1 c6 paraffins 15 0 16 5______________________________________ a series of cesium promoted cu zno al 2 o 3 catalysts containing various quantities of cesium were prepared.
