Abstract: The present work introduces a new solar selective absorber coating (SSAC) for the receiver tube of Concentrated Solar Power (CSP) systems, proposing silver as an infrared reflector application at 550 °C. In past, Italian National Agency New Technologies, Energy and Sustainable Economic Development (ENEA) has developed SSACs suitable applications °C, featuring absorbers based on graded multilayer cermet WN-AlN W-Al2O3 tungsten. Although these coatings ensured properly stable...
A novel strategy for the decarbonization of crude oil distillation was proposed considering two columns located in Sicily that were simulated by adapting equipment datasheet refinery Raffineria di Milazzo (RAM). The approach consists integration topping section with a concentrating solar power (CSP) plant to decrease carbon dioxide emissions and consumed fossil fuels furnaces columns. Three hypothetical scenarios applicative interest considered. In most economically sustainable, use heat...
The dehydrogenation of ethylbenzene to styrene was used as a model an energy intensive endothermic process assess the economic sustainability utilization solar heat from concentrating power (CSP) plant decarbonize industrial chemical processes. To this purpose configuration compatible with hybridization CSP using binary mixture NaNO3/KNO3, 60/40 w/w transfer fluid (HTF) selected. adopted reactor is shell and tube bundle converter 30000 tubes 6 meter length 0.025 m inside diameter that...
We studied the hydrothermal liquefaction (HTL) of digested sewage sludge (DSS) as model waste biomass in batch and continuous reactors. HCOOH KOH were used to improve slurry pumpability. HTL experiments conducted at same kinetic severity factor a reactor 25 mL volume continuously operated tubular with 350 volume. The observed outcomes suggested that it was not possible achieve pumpability native DSS when high concentrated stream suspended solid particles has been fed plant. Using acidic or...
Hydrothermal liquefaction (HTL) can be considered a promising route for the energy valorisation of waste sewage sludge (SS). However, not much information is available on continuous flow processing. In this study, mixed SS was subjected to HTL at 350°C 8 min in reactor with loadings 10 wt% feed flow. The results show that mass recovery reached 88%, biocrude yield 30.8 (3.9 N content). recovered yields are highly dependent selection solvent extraction, and dichloromethane contribute an...
Abstract Recently, the electrochemical treatment of wastewater polluted by recalcitrant organics and containing chlorides was shown to be significantly improved adopting proper operative conditions such as suitable anodes cathodes low current density. In particular, use carbon felt or silver could increase removal TOC reduce formation chlorinated by‐products. this study, attention focused on utilization with main aim evaluate effect air pressure process using phenol model organic pollutant....
Abstract In the last few years increasing attention has been devoted to utilization of electroFenton (EF) and EF based technologies for treatment wastewater polluted by recalcitrant organics. It shown that performances can be strongly improved using ultraviolet (UV) irradiation, e. g., photo‐electroFenton (PEF) method, or pressurized air oxygen, pressurized‐electroFenton (PrEF) one. Although several studies were carried out on degradation many organic pollutants EF, PEF PrEF, a systematic...
Abstract In the last years, an increasing attention has been devoted to utilization of anodic oxidation (AO) technologies for treatment wastewater polluted by recalcitrant organics. Recently, Ti 4 O 7 was proposed as a promising anode AO various Here potential commercial anodes evaluated considering electrochemical synthetic contaminated three very different organic molecules (namely, oxalic acid, phenol and Acid Orange 7), all characterized high resistance AO. The performances were compared...
The key step for both the electrochemical H2O2 production and electro-Fenton (EF) process is cathodic reduction of O2 which adversely affected by low oxygen solubility in water contacted at atmospheric pressure air. In this work, we studied effect current density air on EF using a divided an undivided cell. It was shown that use pressures between 5 15 bar allows to enhance drastically cells best results were achieved presence separator. Moreover, coupled pressurized made it possible...
To date, the management of polluted soils and sediments is challenging because they can be characterized by heterogeneous conditions, miscellaneous contaminants (organic inorganic ones), fine grains low-hydraulic permeability. In these cases, current treatment methods are poorly effective. ElectroChemical Remediation Technologies (ECRTs) considered some main appealing strategies for remediation such complex sites. The ECRTs based on application a relatively low cell potential value, between...
Hydrothermal liquefaction (HTL) of sewage sludge (SS) was performed in the presence metallic Zn, Fe and Ni to investigate their effect on performances process terms product yields quality. Experiments were subcritical water at 350°C for 10 min using each metal individually homogenous hydrogen producers like formic acid (FA) KOH. Interesting results obtained with Zn that when used alone or KOH increased cumulative biocrude (BC) resulted energy recoveries (ER) higher than 100% respect initial...
Hydrothermal liquefaction (HTL) can be considered a promising route for the energy valorisation of waste sewage sludge (SS). However, not much information is available on continuous flow processing. In this study, blended SS was subjected to HTL at 350 °C 8 min in reactor with loadings 10 wt.% feed flow. The results show that mass recovery reached 80 %, biocrude yield 30.8 (N content 3.9 wt.%). recovered yields are highly dependent selection solvent extraction, and dichloromethane contribute...
