Gasification of Waste Tires
Gasification is a thermochemical pathways used to convert carbonaceous feedstock into syngas (CO and H2) in deprived oxygen environment. The process can accommodate conventional feedstock such as coal as well as discarded waste including plastics, rubber, and even MSW due to the high reactor temperature of 1000 to 1600oC. Pyrolysis is another conversion pathway yet it is more selective to the c...
متن کاملUsing Scrap Tires in EAFs as a Substitute for Carbon
EAF plants normally consume coal and coke as reactants, alloying elements, or fuel. The price of these materials varies from € 0.20-0.35/kg. This is while nearly 10 million pieces of tires are annually discarded in Iran. The present study shows that scrap tires can be used as a substitute for coal and coke in EAF plants. Thirteen grades of steel including low, medium, and high carbon steels as ...
متن کاملVacuum pyrolysis of waste tires with basic additives.
Granules of waste tires were pyrolyzed under vacuum (3.5-10 kPa) conditions, and the effects of temperature and basic additives (Na2CO3, NaOH) on the properties of pyrolysis were thoroughly investigated. It was obvious that with or without basic additives, pyrolysis oil yield increased gradually to a maximum and subsequently decreased with a temperature increase from 450 degrees C to 600 degree...
متن کاملSurface Area Determination of Activated Carbons Produced from Waste Tires Using Adsorption from Solution
The following study demonstrates the possibility of producing different activated carbons from a mixture of waste tires and tubes. The mixture was pyrolyzed at different temperatures namely (400,450 and 500 о C) for two hours for the determination of best condition of heating. It was found through the study that semi carbonized marital produced via pyrolyis at 500 о C was the best; thus it was ...
متن کاملStrategic Behaviour in International Metallurgical Coal Markets
This paper analyses whether prices and trade-flows in the international market for metallurgical coals were subject to non-competitive conduct in the period 2008 to 2010. To do so, I develop mathematical programming models – a Stackelberg model, two varieties of a Cournot model, and a perfect competition model – for computing spatial equilibria in international resource markets. Results are ana...
