In this study, the conceptual process flowsheet was developed and the economic feasibility of woody biomass conversion to biofuel as feedstock was analysed by considering several promising experimental processes for lignin depolymerization, such as hydrodeoxygenation and hydrogenolysis, along with lignocellulosic biomass fractionation processes. Th...
Biogas plants can contribute to future energy systems&rsquo / stability through flexible power generation. To provide power flexibly, a demand-oriented biogas supply is necessary, which may be ensured by applying flexible feeding strategies. In this study, the impacts of applying three different feeding strategies (1x, 3x and 9x feeding per day) on...
Modelling and experimental validation of solvent recovery from an aroma mixture by batch distillation process is presented, with particular emphasis of the effect of the prediction of the physicochemical properties and the phase equilibrium data on the content of the aroma compounds in the distillate cuts. The illustrative case study refers to an i...
Supercritical fluid extraction (SFE) and fractionation of products from a complex mixture such as bio-oil, where many compounds are present in low concentrations, is a difficult process to model. This difficulty arises from the uncertainty associated with those interactions between mixture components for which fundamental vapor–liquid equilibrium (...

Wood-like plastic composites were manufactured with a thermoplastic matrix polymer from renewable resources, i.e. high-density poly(ethylene) from bioethanol and a lignocellulosic filler obtained as a byproduct of the industrial distillation of thyme. The potential manufacturing of these composites by injection molding was studied. For this purpose...
This study presents a methodology with tools integration to apply advanced uncertainty propagation and sensitivity analysis in connection with commercial process simulation software. The methodology was applied to two processes: a heat pump system and a molecular distillation process. The input parameters of the selected thermodynamic model, namely...

In this study a supercritical fluid extraction process using carbon dioxide as a solvent was developed and investigated as a potential energy efficient and cost effective alternative to conventional distillation for the extraction and subsequent fractionation of high value renewable chemicals from lignocellulosic bio-oil. Fundamental solubility stu...
