This study investigates enhanced biogas production via co-Hydrothermal gasification (co-HTG) of wet Chlorella vulgaris biomass and hydrochar (HC). Hydrothermal carbonization was applied to valorize struvite containing waste microalgae stream into solid bio-fuel with improved combustion properties. The effects HC quality mixing ratio are investigated on yield, composition carbon conversion ratio. results show that the application blending components promotes H2, CH4 formation selectivity in...
Perfluorosulfonic acid (PFSA) polymers such as Nafion are the most frequently used Proton Exchange Membrane (PEM) in PEM fuel cells. XL is one of recently developed membranes designed to enhance performance by employing a mechanically reinforced layer architecture and chemical stabilizer. The influence water pre-treatment process on physicochemical properties membrane Electrode Assembly (MEA) was investigated. obtained results indicate that pre-treated have higher uptake dimensional swelling...
The proton exchange membrane (PEM) represents a pivotal material and key challenge in developing fuel cell science hydrogen technology. Nafion is the most promising polymer which will lead to its commercialisation. Hybrid membranes of nanosized tungsten oxide (WO3) were fabricated, characterised, tested single cell. incorporation 10 wt% WO3 resulted 21% higher water uptake, 11.7% lower swelling ratio, almost doubling hydration degree, 13% mechanical stability hybrid compared XL. Compared...
Hybrid separation materials intended for the hydrophobic pervaporation process with a new type of fillers were generated. Membranes based on poly(ether block amide) (Peba 2533) containing two organic fillers: 4-(trifluoromethyl)-N-(pyridine-2-yl)benzamide (denoted as F1) and 4-(dimethylamino)-N-(pyridine-2-yl)benzamide F2) fabricated. Novel systematically characterized from material point view subsequently applied in pervaporative binary water-organic mixture. The correlation between (e.g....
There are different factors and indices to characterize the performance of a pervaporation membrane, but none them gives information about their capabilities in area liquid separation compared most convenient alternative, which is distillation. Membrane flash index (MFLI) can be considered first only one that shows if membrane more efficient or not than distillation quantifies this feature too. Therefore, MFLI helps select best alternative case process design. In study, evaluation...
Novel composite membranes employing a poly(ether-block-amide) (PEBAX) copolymer and sulfonated montmorillonite (S-MMT) as filler were developed. The ratio of polyether to polyamide blocks was investigated using PEBAX 2533 4533 based on the membrane properties performance. Additionally, effect changing monitored. interaction between S-MMT nanofiller polymer matrix PEBAX2533 PEBAX4533 well crystalline nature thermal mechanical stability evaluated Fourier Transform Infrared Spectroscopy...
Encouraged by the industrial problem of removing water from methanol solutions, a simple exfoliation method is applied to prepare polyvinyl alcohol (PVA)/laponite nanoclay mixed matrix membranes (MMMs).

Chemical process design is a creative step of engineers that should be supported by different computer-aided tools. Such tools simple and easy to use because synthesis often means the investigation huge number alternatives. During separation liquid mixtures, among many others, distillation pervaporation are usually simultaneously considered frequently as an alternative distillation. To easily compare efficiencies continuous flash distillation, we propose new method, so-called membrane index...
