Abstract

The hydrolysis of carbonyl sulfide (COS) was studied in a gas-liquid reactor at room temperature and ambient pressure in presence of alkanolamines, such as monoethanolamine (MEA), diethanolamine (DEA), methyldiethanolamine (MDEA) and diisopropylamine (DIPA). The activity and stability of the different amines was investigated at fixed COS inlet concentration and reaction volume. The highest removal efficiency of COS was obtained in presence of DEA aqueous solution (25 %), while the lowest COS conversion was observed with the tertiary amine MDEA (< 10 %). A greater COS removal was obtained in presence of the higher reaction volume (400 cm3) that was equal to 25 % for DEA and 26 % for DIPA, respectively. Finally, the evaluation of the kinetic constant for the COS hydrolysis reaction with DEA was performed.

7. Oxidative Decomposition of H2S over Alumina-Based Catalyst

Abstract

An Al2O3-based catalyst was employed for the first time in the H2S oxidative decomposition in order to obtain simultaneous sulfur and hydrogen. The influence of the reaction temperature (in the range of 700–1100 °C) and the contact time (in the range of 17–33 ms) were investigated in terms of H2S conversion, H2yield, and SO2selectivity. Good catalytic performances were obtained at 1000 and 1100 °C with experimental values very close to those ones expected from the thermodynamic equilibrium. At a temperature of 1000 °C, the H2S conversion and H2yield were, respectively, about 50% and 17%; in particular, the SO2selectivity decreased of a magnitude order ∼0.5% with respect to the value observed in the homogeneous case (4%). A predictive mathematical model of H2S oxidative decomposition in the presence of a catalyst was developed through the identification of the main reactions occurring in the system. The results obtained from the kinetic investigations evidenced that the catalyst, in addition to the H2S decomposition reaction and the partial oxidation reaction to sulfur, was able also to promote the SO2conversion by the Claus reaction allowing it to avoid the presence of SO2at the reactor outlet.

11. Il nuovo welfare metropolitano di Bologna e le 'premure' di Ardigò

Abstract

Il saggio analizza anzitutto il modello ardigoiano di welfare, considerandolo come una delle sue "premure fondamentali (ultimate concerns). Si sofferma successivamente sui processi di innovazione che avrebbero dovuto catatterizzare il nuovo modello di welfare: partecipazione; integrazione tra sociale e sanitario; domiciliarizzazione delle cure. Valuta, infine, quali delle proposte ardigoiane hanno effetivamente influenzato lo sviluppo del welfare bolognese e quali sono, invece, gli scostamenti, concludendo che esiste ampio spazio per tradurre in pratica alcune delle più significative idee di Ardigò.
