✦ Synopsis

Three phase catalytic oxidation of sulfur dioxide on activated carbon by oxygen is investigated using a fixed-bed topped by a Jet-Venturi (as gas-liquid contactor) and packed with crushed particles of activated carbon (3.15 to 4.00 mm) as catalyst operating at room temperature and atmospheric pressure. In the conditions where the gas and liquid are fed. at venturi level, cocunently downward through the fixed bed, some hydrodynamic characteristics (flow reghue and pressure drop) and overall mass transfer coefficient for SO2 are determined. Using these results and a kinetic law obtained in a slurry reactor containing fine particles of activated carbon (Kiared et al., 1990 and Kiared, 1992), plug flow with internal diffusion and total wetting effrcien a mean value of De obtained (1.25 IO-10 m c% model is used for interpreting the experimental data. With /s), obtained.

KEYWORDS good agreement between model and experiments was

Verlif'ix reactor, activated carbon, conversion of SO2, effective diffisivity.

## Abstract New experimental results were obtained for the mutual sensitization of the oxidation of NO and methane in a fused silica jet‐stirred reactor operating at 10^5^ Pa, over the temperature range 800–1150 K. The effect of the addition of sulfur dioxide was studied. Probe sampling followed by

A study has been made of the absorption of gaseous oxygen in a thiophenol solution. The chemical reaction which occurred in solution was promoted by a copper chloride-pyridine catalyst. There were two reaction products, diphenyldisulphide and diphenylthiolsulphinate. In some experiments the liquid w
