Novel micro-structured string-reactor designed as catalytically active wires placed in parallel into a tube was developed. The small diameter of the channels (∼100 m) leads to a short radial diffusion time, a narrow residence time distribution (RTD), and a low pressure drop. This reactor was applied for the oxidative steam-reforming of methanol (OSRM) to produce hydrogen in autothermal mode for...

This study addresses the development of a compact reactor for oxidative steam-reforming of methanol (OSRM) to produce hydrogen in autothermal mode for fuel cells. The string reactor uses catalytically active brass wires with a diameter of 500 mm placed in parallel into a tube. The micro-channels in the reactor for gases are formed between the wires presenting hydrodynamics similar to the one in...

A three-phase fixed-bed reactor for selective hydrogenation of butadiene in liquid phase with toluene as solvent is modeled using published kinetics. Thermodynamic and transport properties are estimated from models and correlations available in the literature. The model incorporates momentum and energy balances and mass transfer resistances. The results show that use of toluene increases the yi...

A novel plasma-driven catalysis (PDC) reactor with special structure was proposed to remove vehicle exhaust gas. The PDC reactor which consisted of three quartz tubes and two copper electrodes was a coaxial dielectric barrier discharge (DBD) reactor. The inner and outer electrodes firmly surrounded the outer surface of the corresponding dielectric barrier layer in a spiral way, respectively. Na...

This paper describes an automated reactor in which reactions can be carried out using at least one gaseous reagent and one liquid reagent at a pressure ofup to 5 bar. The reactor was used to produce a hydrogenation reaction, in which system all operations, i.e. introduction of liquids and gases, control and regulation of pressure, temperature and volume of gases introduced and finally draining ...

An economic magnetic fusion reactor favours a high ratio of plasma kinetic pressure to magnetic pressure in a well-confined, hot plasma with low thermal losses across the confining magnetic field. Field-reversed configuration (FRC) plasmas are potentially attractive as a reactor concept, achieving high plasma pressure in a simple axisymmetric geometry. Here, we show that FRC plasmas have unique...

The current work demonstrates the feasibility of atmospheric pressure non-thermal plasma technique for NOx pollution control. Atmospheric pressure dielectric barrier discharge plasma reactor has been constructed for the treatment of the exhaust of 4kWs free load diesel engine. The nature and properties of the discharge were identified through studying electrical characterization of the discharg...

The effect of organic loading rate (OLR) on a pressurized anaerobic filter was studied in a laboratory two-phase anaerobic digestion system. The anaerobic filter was operated successively at two working pressures (9 bar and 1.5 bar). The OLR(COD) for each pressure was increased from 5 to 17.5 kg·m·day. The best performance of the reactor at 9 bar was observed at OLR(COD) of 12.5 kg·m·day and hy...
