We are making a research on the catalytic steam reforming of various materials ranging from light hydrocarbons to heavier oils at low and high temperatures. Our research covered a study of the catalytic steam reforming of kerosene and pure hydrocarbons, very little study of which has been made thus far. The following results have been obtained from this study concerning the effect of various reaction conditions on gasification of kerosene at a low temperature.Atmospheric pressure: When pressure is increased to as high as 3kg/cm2•G, the rate of gasification becomes higher than that at atmospheric pressure. However, there is hardly any change noticed in the rate of gasification at pressures over 3kg/cm2•G.Liquid space velocity: The rate of gasification increases as high as 100 per cent at any liquid space velocity below 1.0; but it decreases with an increase in the liquid space velocity over 1.0.Steam/carbon ratio: The rate of gasification shows no change at any steam/carbon ratio up to 3.0; but it decreases with an increase in the ratio over 3.0.Temperature: With a rise in temperature, the rate of gasification increases sharply.Materials: Paraffinic hydrocarbon is most easily gasified, while aromatic hydrocarbon is the hardest to gasify. Petroleum is gasified at a moderate speed. A gaschromatographic analysis shows that the composition of unreacted hydrocarbon is the same as that of materials used.In all cases of the above test, no carbon has been separated from the catalysts.
