Web15 de jun. de 1978 · The stationary-state reaction between H 2 and O 2 over Pt SiO 2 catalysts has been studied between 273 and 373 K in both excess hydrogen and excess oxygen on samples with dispersion of platinum varying between 1.0 and 0.14. In excess hydrogen, the catalyst with the highest dispersion was seven times more active at 273 K … WebOxyhydrogen is a mixture of hydrogen (H 2) and oxygen (O 2) gases. This gaseous mixture is used for torches to process refractory materials and was the first [1] gaseous mixture used for welding. Theoretically, a ratio of 2:1 hydrogen:oxygen is enough to achieve maximum efficiency; in practice a ratio 4:1 or 5:1 is needed to avoid an oxidizing ... play knowing you jesus lyrics
