A Co-Mg/diatomaceous earth catalyst, prepared by slow precipitation, consisted of two separate phases: small needles of a Co-Mg phase, and large particles of the diatom fragments. N sorption measurements indicated a much higher pore volume for the catalyst than for a control catalyst prepared by fast precipitation. Catalyst activity in the Fischer-Tropsch synthesis at 155 kPa declined at an unusually fast rate, which was accompanied by increased CH, selectivity and decreased Schulz-Fiery chain growth constant. Hydrogen treatment temporarily restored catalyst activity but did not stop the declines.

Pretreatment in ZI followed by synthesis gas at 300”showed the thickest layer of amorphous carbon in TBM, and the amount of carbon deposited mcrcased with increasing temperature.

Describes how in liquid phase Fischer-Tropsch synthesis at 215-222”. apparently new active sites are formed as the level of cobalt on steamed, acid-washed Y xeolite is increased from 8 to 28 wt%. If a ‘ven volume of support can carry higher levels of catalytically active co$ ah than previously thought possible, a superior liquid phase Fischer-Tropsch catalyst can result. This is partrcularly true if these catalysts also retam the ability to produce low levels methane which, in fact, they do seem to do.
