We developed a new catalyst for steam reforming plant using tubular reactor and also developed a new method for reaction analysis using simulation model of the reactor, which is needed for designing a reforming furnace.<BR>The new catalyst consists of Ruthenium as active metal and Ag<SUB>2</SUB>O, La<SUB>2</SUB>O<SUB>3</SUB> as promoters supported on α-Al<SUB>2</SUB>O<SUB>3</SUB> as carrier. In the bench scale test, this catalyst was found that it had high activity at low temperature and the property to suppress carbon deposition even though the steam ratio was as much as 2. 0 (H<SUB>2</SUB>O-mol/C-mol), when LPG (C<SUB>4</SUB>H<SUB>10</SUB>) was fed to the reactor as feedstock.<BR>On the pilot scale plant with a reactor of 4-inches diameter, we found that olefins which was produced by catalytic cracking of LPG were detected on the new catalyst much less than on the conventional Ni-catalysts, while methane was detected much more. We have also made sure that the durability of the new catalyst were satisfactory through the long term operation for more than 2400 hours.
