K 9700 A B S T R A C T CATALYST ACTIVATION During the activation of Co/Zr/SiO2 catalysts by contact- ing them with a H2-containing gas at a temperature between 200 and 350°C and a H2 partial pressure between 0.001 and 75 bar, the H2 partial pressure is gradually or stepwise increased from an initial value Image to an ultimate value Image in such a way that Image . The time required for the activation can be drastically re- duced (to about 10 hours or less) by carrying out the activation as described hereinbefore as a result of which catalysts with an improved activity and selectivity are obtained for the conversion of a mixture of CO and H2 into hydrocarbon.
