(1) The effects on the Co type catalyst of such promoters as B2O3 and Cu, and the combined effects of ThO2 and CeO2 on the catalytic activity have been investigated and discussed.
(2) The effects of the pre-treatment on the catalytic activity have been investigated and discussed.
(3) It has been shown that there is a fundamental difficulty to generalize a parallel relationship between the gas contraction and the oil yields.
(4) In discussing the catalytic activity, that the CH4 formation must be carefully segregated whenever we speak of the catalytic activity as to its oil forming ability has been pointed out as of paramount im？ortance.
