Energetic valorization of waste tires

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...

Vacuum 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...

Valorization of biomass: deriving more value from waste.

Most of the carbon-based compounds currently manufactured by the chemical industry are derived from petroleum. The rising cost and dwindling supply of oil have been focusing attention on possible routes to making chemicals, fuels, and solvents from biomass instead. In this context, many recent studies have assessed the relative merits of applying different dedicated crops to chemical production...

Removal of No2 on Active Carbons Obtained from Waste Tires

Introduction The production of scrap tires only in the EU, USA and Japan is around 6 million tones per year. As the associated automotive industries grow the huge quantity of waste tires presently produced in the world will certainly increase in the future [1]. Thus the disposal of scrap tires becomes a serious environmental problem. The production of activated carbons from solid wastes is one ...
