Adsorption of γ-Valerolactone: An Alternative for Solvent Recovery after Conversion of Lignocellulosic Biomass to Fermentable Sugars [PDF]

Chemical and Biochemical Engineering Quarterly, 2022
The γ-valerolactone is an effective solvent in solubilizing lignocellulosic biomass fractions, although it inhibits microbial activity. To avoid the negative effects on the metabolism of microorganisms, even small quantities of γ-valerolactone need to be

Dynamic models for start-up operations of batch distillation columns with experimental validation [PDF]

, 2004
The simulation of batch distillation columns during start-up operations is a very challenging modelling problem because of the complex dynamic behaviour. Only few rigorous models for distillation columns start-up are available in literature and generally

Determination of polybutylene terephthalate polycondensation equilibrium constant using a batch reactor [PDF]

Macromolecular Symposia, 2004
AbstractThe PBT polycondensation equilibrium constant at 255°C was determined using a batch reactor. Starting from a Polybutylene terephthalate (PBT) prepolymer having a degree of polymerisation of 12.7, equilibrium experiments were performed in the range of 1 to 50 mbar.
