(1) The glass powder, each particle of which is spherical, was prepared, and their specific surface areas have been determined. (2) Using this glass powder as adsorbent, the amounts of palmitic acid and benzoic acid, adsorbed from their benzene solutions, have been measured respectively. (3) Two methods of determining adsorption, have been used. In the first method, the density determination by the float method is applied to determine the change of concentration of solution before and after the adsorbing procedure, and in the second method, the surface area of insoluble film on water has been measured by surface balance. (4) It has been concluded that the thickness of the adsorption layer is monomolecular.
(1) The experimental apparatus and the experimental procedures were described for the investigations on the Fischer—Tropsch reaction with special references to its catalytic mechanism. (2) The durability of the catalyst used was discussed in connection with the investigation of catalytic activity as to its liquid hydrocarbons synthesis. (3) Some properties of the reaction products were tabulated. (4) Some consideration of CH4 formation in connection with our proposed mechanism werw presented and correlated with the experimental results.
The experimental procedure and the preparations of the catalysts used are given in detail. The effects on the activity of the carbide and of the reaction products are found to be small—if at all. The results of the runs in dry system are tabulated, and each run is briefly described. Short discussions on the results are also given. A fuller discussion on them is reserved for a subsequent paper.
(1) It has been found that pure MgO·Al2O3 is formed at first in this reaction, and the solid solution rich in A12O3 is formed gradually when an excess of Al2O3 is present. (2) Although there exists a rapid initial reaction, the later reaction is controlled by the diffusion process with an energy of activation of 41.1 Kilocalories per mole. (3) The reaction proceeds more easily with the mixtures containing an excess of MgO than with the other mixtures.
