Methane production from orange peel pressing liquid: A kinetic study
Abstract This paper studies the anaerobic fermentation of orange peel pressing liquid (OPPL), in semi‐continuous digesters under thermophilic conditions (50, 55 and 60°C), using rabbit manure as inoculum which has been previously conditioned to substrate and temperature. Experimental data have been fitted, at each temperature, to the Chen and Hashimoto model. Kinetic parameters governing the process have been obtained. It can be observed that both μm and K decrease when temperature increases, within the studied range, whereas the calculated minimum hydraulic retention time, θm, increases with temperature, as tested experimentally.
Viscosity of n-alcohol binary mixtures
In this paper liquid mixture viscosities at 25 °C for 18 binary systems formed by primary n-alcohols have been measured. These values were fitted to Topological Treatment of Mixtures (T.T.M.) The pure compound topological description is obtained following the DARC system rules. A weighting function was introduced to obtain the topological description of a mixture. The results obtained with this model agree with experimental data (average deviation less than 2% in all cases). Dans cette etude, nous avons mesure des viscosites de melanges liquides a 25°C pour dix-huit systemes binaires formes par des n-alcools primaires. Ces valeurs ont ete calees par le traitement topologique des melanges (T…
