kinetic modeling and parameters identification based on metaheuristic optimization techniques for extraction process of marrubium vulgare l. essential oil
Authors
abstract
recently, increasing attention has been directed to the isolation of natural active components from various medicinal plants. in the present research, the extraction of essential oil from horehound (m. vulgare l.) is presented. effects of mass ratio and particle size on the process performance were studied and kinetics were determined. the chemical composition of the volatiles present in m. vulgare l. was evaluated for the sample extracted in the optimum conditions (mass ratio, 3 kg/m3 and particle size,0.1

The antioxidant activity of Marrubium peregrinum essential oil, collected from three different locations [Backo Gradiste Rimski Sanac (No.1), Novi Knezevac (No.2) and Senta (No.3)] was evaluated as free radical scavenging capacity (RSC), together with inhibition on xanthine-oxidase and effects on lipid peroxidation (LP). RSC was assessed measuring the scavenging activity of the essential oils o...

In this study simulation and optimization of an industrial acetylene hydrogenation reactor was studied. Three well known kinetic models were used for a nearly similar catalyst to predict the industrial data. Due to the complexity of the reactions, none of the offered kinetic models could be considered as an exact kinetic model and it is necessary to determine the kinetic parameters. One of the ...
