            For the synthesis of hydrocarbons from CO and H₂. a Co catalyst is supported on alimina, which has been heated for 6 hr. at 850º-1,000º C. to convert it to the a form.  This form is alumina is not attacked by alkali.  Using a catalyst containing 1 part by weight of Co. 1-2 parts of a alumina and 0.1-0.15 part Zn oxide, a yiled of 135 gm. of oil per m.³ of synthesis gas is obtained.  70% of this oil b. >320º C.  If ordinary Al₂O₃ is used, however, the yield is only 30 gm. of oil per m.³, of which only 50% b. >320º C.
