Numerical study of gasification pelletized municipal solid waste using multi-stage air inlet downdraft gasifier

Formation of Dioxins and Furans during Municipal Solid Waste Gasification

Thermal treatment is an interesting strategy to dispose of municipal solid waste: it reduces the volume and weight of the material dumped in landfills and generates alternative energy. However, the process emits pollutants, such as dioxins and furans. The present study evaluated MSW gasification-combustion integrated technologies in terms of dioxin and furan emission; and compared the obtained ...

Thermal Plasma Gasification of Municipal Solid Waste (MSW)

Rapid economic development has led to an annual increase in municipal solid waste (MSW) production. According to the US Environmental Protection Agency (US EPA), MSW generation has increased by a factor of 2.6 since 1960 [1]. The US EPA endorsed the concept of integrated waste management that could be tailored to fit particular community’s needs. Sustainable and successful treatment of MSW shou...

Tar Analysis in Syngas Derived from Pelletized Biomass in a Commercial Stratified Downdraft Gasifier

A study was conducted to quantify tar formation in a stratified downdraft gasifier using wood pellets. The effect of biomass flow rate on tar concentration was also analyzed, and more than thirty compounds in tar were quantified. Among the different compounds in tar, tertiary condensed products such as toluene, o/p-xylene, naphthalene, phenol, styrene, and indene were observed in significant am...
