The anaerobic treatability of malt whisky distillery wastewater was investigated. Biochemical methane potential (BMP) experiments were conducted both with and without basal medium (BM) to observe the effect of nutrient supplementation. For batch reactors containing no nutrients but only NaHCO3, net total gas production at the end of 29 days were observed as 0.019 m 3 gas/kg COD removed. With nu...

The work studied the characteristics of membrane catalysts in reaction methane carbonate conversion as a model reaction. This process produces synthesis gas (a 1:1 mixture Н 2 and СО), which can be used to make many products, including synthetic fuels (in FischerTropsch process). One serious problems is presence side reactions that prevent production with required ratio products (H :CO=1:1).Mem...

This study introduces spatially targeted decontamination using a synergistic combination of dielectric barrier discharge (DBD) flow actuation and ozone generation. Here, we relate the spatial distribution local microbial decontaminations in an enclosure to that concentrations caused by DBD generation two reactors with contrasting actuation, Fan Comb reactors, run at equal power 1 ± 0.03 W for 3...

Light-off of the partial oxidation of methane to synthesis gas on a rhodiumcoated cordierite honeycomb monolith at short contact times is studied experimentally and numerically. The objective of this investigation is a better understanding of transient processes in catalytic oxidation reactors. The numerical simulation predicts the time-dependent solid-temperature distribution of the entire rea...

Multiphase impeller stirred tank reactors enhance mixing of reacting species used in a variety of chemical industries. These reactors have been studied based on Computational Fluid Dynamics (CFD) that can be used in the analysis, design and scale up of these reactors. Most of the researches done in this area are limited to single phase reactors, and a few remaining two phase flow investigat...

Gas holdup and bubble size are important parameters for simulation and designing in bubble column reactors. Because based on these parameters, the available gas-liquid interfacial area is defined for mass transfer. In this paper, the results of applying magnetic fields on the velocity field and volume fraction of gas holdup are reported. Hydrodynamics of the bubble column in the reactors is inv...

Due to the density differences between gases and liquids, gas supply often limits conversion of gas-liquid reactions in slug flows. This paper investigates permeation reacting into an existing flow fluorinated ethylene propylene capillaries up 40 m length, representing a significant sizing-up tube-in-tube reactors (maximum 4 m). The amount introduced can be estimated with coefficients given lit...

Abstract Partially hydrogenated fatty acid methyl ester (H-FAME) is conventionally produced through partial hydrogenation under high pressure and elevated temperature in the presence of a catalyst. Herein, novel green, catalyst-free, non-thermal atmospheric dielectric barrier discharge (DBD) plasma was employed instead conventional method to hydrogenate palm FAME. H-FAME became more saturated w...

Abstract Direct conversion of methane into chemicals and fuels under mild conditions has been considered as a ‘holy grail’ chemistry catalysis in the 21st century. Plasma-catalytic partial oxidation (POM) to higher-value liquid over supported transition metal catalysts (Ni/?-Al2O3, Cu/?-Al2O3 Fe/?-Al2O3) investigated co-axial dielectric barrier discharge (DBD) reactor at room temperature atmosp...
