Interest in the production of hydrogen from hydrocarbons has grown significantly recently. In order to achieve high surface to volume ratio with reasonable pressure drop, monolithic reactors are used. The goal of this work is to develop a two-phase (gas & solid) transient catalytic ...

Surface acoustic wave gas sensors use a chemically sensitive resistive layer to detect gas concentration. The resistivity of the sensing material, the sensing layer thickness, and the spacer layer thickness all affect the surface wave propagation velocity. Existing analytic theory ... Per saperne di più
Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA) are commonly used for separation/purification of gas mixtures in industrial processes. The cycle time of industrial TSA processes usually ranges from several hours to days. The reason for this long cycle time is the ... Per saperne di più
Patterned two-dimensional (2D) materials have recently become promising candidates for separation processes in both gaseous and aqueous phases, due to mechanical strength and atomic thickness. Conventional separation technique using 2D materials are limited by the surface charge of 2D ... Per saperne di più
Ion mobility spectrometry provides fast detection of very low concentrations of chemical substances. Simple instrumentation combined with high sensitivity and high selectivity are the advantages of this technique. One well established field of application is the detection of hazardous ...

Greenhouse gases trap heat and make the planet warmer. The main greenhouse gases emitted by human activities are: Carbon dioxide (CO2). The use of fossil fuel is the primary source of CO2 [1, 2]. Accordingly, there is a need for an efficient and novel separation processes for removal of ... Per saperne di più
A mathematical model is developed for the stripping of CO2 from rich solvent. The rich solvent (aqueous NaOH) is used in CO2 absorption from natural gas through gas-liquid hollow fiber membrane contactor. The polyvinylidene fluoride (PVDF) hollow fiber membrane was fabricated via ... Per saperne di più
A MEMS based Knudsen’s pressure gauge working in the range of 1e-5 mbar to 10 mbar is designed and simulated in COMSOL. The working principle is based on Knudsen’s forces that arise when two plates are held at different temperatures and their separation is comparable to the mean free ... Per saperne di più
Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, ... Per saperne di più
In Eiceman and Karpas’s book Ion Mobility Spectroscopy (2005), they define Ion Mobility Spectroscopy (IMS) as "the principles, methods, and instrumentation for characterizing chemical substances on the basis of velocity of gas-phase ions in an electric field." The production of the ... Per saperne di più
