Characteristics of rotating arc for CF4 removal
Characteristics of CF4 treatment process with a rotating arc are investigated under different thermal and non-thermal plasma conditions. To generate high temperature or non-thermal plasma conditions, a rotating arc reactor is operated with various operating conditions, which are species of carrier gases, flow rates, and input power. Test results reveal that that high temperature conditions caused ...

Pyrolysis processing of used old tyres by thermal plasma technology
Thermal plasma pyrolysis of used old tyres was studied in a nitrogen plasma reactor in order to evaluate the material and energy recycling potential. The main gaseous products from thermal plasma pyrolysis of used old tyres were identified by chromatography as H2, CO, CH4, C2H2, C2H4. In the presence of water steam injection into the plasma reactor, the yield of H2 and CO can reach up to 38.3% of ...

Large-scale synthesis of nanopowders by transferred arc thermal plasma
The present work describes the preliminary results on large-scale synthesis and characterisation of copper (Cu) and aluminium nitride (AlN) nano powders by transferred arc thermal plasma technique. The transferred arc was used to vaporise the precursor materials (Cu, Al metal 99.9% pure). Nano particles are formed in the gas phase as a result of homogeneous nucleation. The vapours of Al were ...

Decomposition of benzene by non-thermal plasma processing: Photocatalyst and ozone effect
Plasma technology has some shortcomings, such as higher energy consumption and byproducts produced in the reaction process. However non-thermal plasma associated with catalyst can resolve these problems. Therefore this kind of technology was paied more and more attention to treat waste gas. A hybrid system comprising a non-thermal plasma reactor and nanometer titanium dioxide catalyst was used ...

Waste Advantage Magazine- The use of Thermal Plasma Technology for treating APC Residues
The growth in Energy from Waste plant capacity is leading a corresponding increase in the generation of Air Pollution Control (APC) Residues, making it one of the fasted growing waste sectors in the UK. In this article published in Waste Advantage Magazine, Dr Tim Johnson from Tetronics discusses how plasma technology is one solution to this issue. ...

Catalytic decomposition of NO2 over a copper-decorated metal-organic framework by non-thermal plasma
Nitrogen oxide (NOx) causes significant impacts on the environment and human health, and nitrogen dioxide (NO2) is the most toxic and prevalent form of NOx in the atmosphere. Its removal and catalytic degradation into non-harmful species (i.e., N2) are thus important challenges. A great deal of effort has been devoted to developing catalysts for deNOx processes with a focus on NO reduction from ...

Recovery of Ruthenium and Other PGMs from Spent Petrochemical Catalysts - Case Study
The recovery of platinum group metals from spent petrochemical catalysts has economic benefits by the protection of the supply chain of these valuable and rare metals, thereby helping to create a sustainable value chain in the petrochemical industry for catalysts. Introduction The platinum group metals (PGMs) are used extensively in catalysts for the petrochemical industry owing to their ...
