The present experiments on the Fischer-Tropsch synthesis have been made with the reactor which was placed in a bath of oil boiling under a reduced nitrogen pressure. The heat transfer efficiency referred to the out-side wall of the reactor has been improved considerably, and, as a consequence, the magnitude of the bed over-temperature remains comparatively small, in spite of the high yield of the product attaining 24∼26 kg./day. The axial and the radial temperature profiles have been separately calculated on the basis of the concentration gradient determined along the heights of the reactor: first the calculation of the former profile under the assumption of uniform temperature across the bed, and secondly that of the latter profile at a cross section in the neighborhood of which the axial temperature is approximately constant. By the convenient choice of 600 kcal./m<SUP>2</SUP> hr. °C for the tube wall coefficient of heat transfer referred to the out-side wall of the present reactor, the calculated axial temperature profile is in good agreement with the experimental profile except for a small intermediate range.
