Abstract

The design of torrefaction processes for biomass conversion are examined in this research, with a focus on the potential of this process as a sustainable energy source in Botswana. Torrefaction is a thermal treatment process that improves properties of raw biomass for use as a biofuel or for co-feeding with coal to reduce carbon emissions. The potential of biomass as an alternative energy source is has not been fully realized in Botswana as there are research gaps on the available biomass resource and its suitability for treatment processes such as torrefaction. This review identifies the gaps and gives information on reactor design, process conditions, and economic feasibility specific to torrefaction. This gives a foundation for the research to be done specific to Botswana for implementation of a torrefaction plant. The review shows ways in which the government of Botswana is promoting the development of the clean energy sector.
