The membrane reactor is proposed in this work as a system with high potential to efficiently recover the hydrogen (H2) stored ammonia (NH3), which has been recently an alternative for H2 storage. With technology, NH3 decomposition and high-purity separation are simultaneously performed within same unit, efficiency achieved at lower temperature compared conventional systems, leading energetic economic benefits. was experimentally Pd-based over Ru-based catalyst performance of packed bed were...
The oil yield and quality of pyrolysis from microwave heating biomass was established by studying the behavior Larch in processing. This is first study to use a processing technique methodology that fundamentally scalable, which basis design for continuous system can be derived maximize quality. It shown systematically sample size vital parameter has been overlooked previous work this field. When controlled, liquid product comparable conventional achieved at an energy input around 600 kWh/t....
The production of NO x from air and + O 2 is investigated in a pulsed powered milli‐scale gliding arc (GA) reactor, aiming at containerized process for fertilizer production. Influence feed mixture, flow rate, temperature, Ar content are varying specific energy input. findings correlated with high‐speed imaging the GA dynamics. An 40–48% was optimum, an enhancement 11% Addition preheating resulted lower Lower rates produced higher concentrations due to longer residence time GA. volume...
In this work a novel reactor concept referred to as Membrane-Assisted Chemical Looping Reforming (MA-CLR) has been demonstrated at lab scale under different operating conditions for total working time of about 100 h. This combines the advantages Looping, such CO2 capture and good thermal integration, with membrane technology better process integration direct product separation in single unit, which its turn leads increased efficiencies important benefits compared conventional technologies H2...
Membrane technology applied in the chemical and energy industry has potential to overcome many drawbacks of conventional technologies such as need large volume plants CO2 emissions. Recently, it been reported that this might become more competitive when operated at high temperatures. This is mostly associated with required heat integration scale. However, good membrane stability combined permeation rates perm-selectivities, only achieved intermediate/low temperatures (< 500 °C). When these...
A gliding arc plasmatron (GAP) is very promising for CO2 conversion into value-added chemicals, but to further improve this important application, a better understanding of the behavior indispensable. Therefore, we study here first time dynamic GAP by means high-speed camera, different reactor configurations and in wide range operating conditions. This allows us provide complete image arc. More specifically, body shape, diameter, movement rotation speed are analyzed discussed. Clearly, shape...
A gliding arc plasmatron (GAP), which is very promising for purification and gas conversion, characterized in nitrogen using optical emission spectroscopy high-speed photography, because the cross sections of electron impact excitation N2 are well known. The temperature (of about 5500 K), density (up to 1.5 × 1015 cm−3) reduced electric field 37 Td) determined an absolutely calibrated intensified charge-coupled device (ICCD) camera, equipped with in-house made arrangement simultaneous...
Organic capping agents are necessary for metallic nanoparticle preparation via colloidal method; however, complete removal of the agent and cleaning metal surface is a well-known challenge in application. In this Article, we show that polyvinyl alcohol (PVA)-stabilized palladium nanoparticles (Pd NPs) were prepared immobilized on activated carbon (AC). Different acids (HCl H2SO4) used to adjust pH, thus enhancing adsorption colloid support. The catalysts characterized by TEM,...
One alternative for the storage and transport of hydrogen is blending a low amount (up to 15 or 20%) into existing natural gas grids. When demanded, can be then separated, close end users using membranes. In this work, composite alumina carbon molecular sieves membranes (Al-CMSM) supported on tubular porous have been prepared characterized. Single permeation studies showed that H2/CH4 separation properties at 30 °C are well above Robeson limit polymeric H2 H2–CH4 mixture gases, containing...
The use of biogas as feedstock for hydrogen production was widely proposed in the literature last years a strategy to reduce anthropogenic carbon emissions. However, its lower heating value compared natural gas hampers revamping existing reforming plants. composite molecular sieve membranes upgrading (CO2 removal from biogas) investigated experimentally this work. In particular, ideal perm-selectivities and permeabilities above Robeson plot CO2/CH4 mixtures have been obtained. These show...
