Gradientless reactor for gas-liquid reactions

Kinetics of catalytic oxidation of aqueous sodium sulfite

“…Thus we have carried out numerous experiments on the effect of oxygen, and have found that the reaction is first-order in oxygen in the partial pressure range 0.21-1 arm. This is in agreement with Refs [13][14][15]. In the lower partial pressure range, we have found the reaction to be second order in oxygen which is in agreement with [4].…”

Small Scale Laboratory Reactors

“…This combines an earlier design of a catalytic wall reactor by Ford and Perlmutter [150] with a novel gas-liquid reactor designed by Schmitz and Manor [151]. In this hybrid reactor, a high speed rotor wipes a liquid feed as a continuous thin film onto a catalytically coated wall.…”

“…Complete catalyst wetting is therefore assured. Residence time studies have confirmed that the liquid phase is well mixed, and the rotor (operating at 2500 rpm) was assumed to produce vigorous mixing of the gas phase [151]. The reactor should therefore operate as a CSTR, and the global reaction rate is available from the simple mass balance (equation 1).…”

“…The reactor should therefore operate as a CSTR, and the global reaction rate is available from the simple mass balance (equation 1). The gas-liquid interfacial mass transfer rate was shown to be at least 30 times that obtainable in other gas-liquid reactors [151]. Carberry has measured values of gasliquid and liquid-solid mass transfer coefficients for the catalytic wall version [147].…”
