Chlorine behavior study in the process of torrefaction and pelletizing of woody biomass for power generation

Abstract

In the face of all insecurity of fossil fuels, its negative impacts and their prediction end, global society has been seeking alternative energy sources to replace the non-renewable energy. Biomass energy - a renewable energy - could be a good candidate for complementation and optimization of fossil fuels. Among the thermochemical processes, torrefaction is emerging as the method of heat pretreatment eliminates many of the limitations associated with raw biomass - in nature. The wood biomass may be used in various forms such as firewood, wood chips, briquettes and pellets. It is known that wood pellets market is the most common product in the international market biomass. Wood pellets not torrefied produced in tropical countries, are not accepted in the European market due to the high chlorine content in hardwoods. However, there is insufficient data on chlorine behavior during the roasting process. The low chlorine content is required to prevent corrosion in boilers and formation of dioxins, which are a risk to human health to be persistent, bioaccumulative toxic and. This adaptation to international standards would strengthen the export of pellets produced in the tropics to the cold climate countries. Thus, this paper aims to study the chlorine behavior during the roasting process and pelletization of woody biomass, in order to meet the required concentration in European standards (> 0.02% m / m) for use as fuel power generation.
