The effect of residual chlorine on the metal-catalyzed reaction of solid calcium oxide with a gas mixture of methane and water vapor (CaO + CH4 + 2H2O → CaCO3 + 4H2) is investigated at temperatures in the range 613–713 K, using solid samples of I

With noble metal catalysts (Pd, Pt, Rh, Ir) present, hydrogen is formed by the interaction of solid calcium oxide with gas mixtures of methane and water vapor, according to CaO + CH4 + 2H2O → CaCO3 + 4H2. Among the metals, Ir and Rh are so active t

A study of the hydrogenation of solid CaCO3 has shown that the addition of Pd and Ir catalysts causes a change in the gaseous product and, consequently, in the kinetics of the reaction. In the absence of catalyst, CO is formed at higher than 700 K wi

The effect of cold-working on hydrogen solubilities in the dilute region (α phase) has been investigated for Pd1-xNix(x≤0.2), Pd1-xPtx(x≤0.19), and Pd1-xNi(1/2)xAg(1/2)x(x≤0.2) alloys by measuring pressure-composition isotherms between 273 and

The purpose of this communication is to determine whether the solubility enhancements for cold-worked Pd-Ni alloys increase or decrease with atom fraction of Ni. Substitutional Ni atoms contract and Pd lattice, in contrast to the lattice expansion re

The role of hydrogen in carbon deposition on Ni has been studied at H2/CO < 1 and 698 K by determining the respective rates of the carbon-forming reactions: (1) CO + H2 →-C + H2O and (2) 2CO → C + CO2. The steady-state rate of reaction (1) increa

The effect of annealing temperature on hydrogen solubilities in the dilute region (α phase) has been investigated for cold-worked Pd-Ag alloys containing from 5 to 40 atomic % Ag by measuring pressure-composition isotherms between 273 and 348 K. The
