  • Application of stage condensation of tar during pyrolysis of high ash semi-bituminous-Morupule mine coal 
    Akofang, Leonard; Agachi, Paul Serban (Genesis Sustainable Future Ltd, 2021-05-05)
    Botswana high-ash semi-bituminous coal produced by Morupule mine is under-utilized due to a lack of knowledge in possible applications of derivative products such as tar, syngas, and charcoal. This study is aimed to determine ...
  • Effects of biomass/coal copyrolysis parameters on the product yield: a review 
    Thibanyane, Ntebogang; Agachi, Paul Serban; Danha, Gwiranai (Elsevier B.V., 2019)
    Pyrolysis is one of the prospective processes that can be utilized to obtain high value chemicals and energy from coal and biomass. Coal-biomass co-pyrolysis presents a green, low-risk, cheap, sustainable, renewable energy ...
  • Enhancement of the pyrolysis process using ultrasound 
    Botha, Daniel Erich; Agachi, Paul Serban; Muzenda, Edison (Botswana International University of Science and Technology, 2017-06)
    It has been estimated that Botswana has more than 200 billion tons of coal locked up in its underground reserves. The logistics for export purposes simply do not exist to get these vast resources to the markets. There ...
  • Methanol synthesis chemistry and process engineering aspects: a review with consequence to Botswana chemical industries 
    Balopi, Babusi; Agachi, Paul Serban; Danha, Gwiranai (Elsevier B.V., 2019)
    In a highly competitive world of commercial production of methanol, it is critical to understand and get methanol (CH3OH) synthesis chemistry and process engineering aspects of methanol production correctly. Methanol ...
  • Pyrolysis of coal dust for the production of tar and useful products 
    Rapoo, Mpho Thabang; Muzenda, Edison; Agachi, Paul Serban (Botswana International University of Science and Technology (BIUST), 2017-06)
    Coal mining for electricity production at Morupule coal mine in Palapye generates a considerable amount of fines or dust. The fines are generated through coal disintegration during various processes such as drilling, ...
  • Quantitative devolatilization of Botswana coal in a pilot scale plant 
    Makoba, Mmoloki; Agachi, Paul Serban; Muzenda, Edison (Botswana International University of Science and Technology (BIUST), 2017-06)
    Coal gasification is a new and clean coal conversion technology that converts coal to liquids and synthetic gas to be used in power generation and chemical products. Botswana coal was studied in a pilot plant to produce ...
  • A review on Botswana coal potential from a pyrolysis and gasification perspective 
    Makoba, Mmoloki; Botha, Daniel Erich; Rapoo, Mpho Thabang; Szabó, László Zsolt; Shomana, Thapelo; Agachi, Paul Serban; Muzenda, Edison (Faculty of Chemical Technology and Biotechnology of the Budapest University of Technology and Economics., 2021)
    Coal pyrolysis and gasification are promising options for the future of Botswana as the country has large coal reserves with severe limitations in terms of export options. Coal characterization facilities will be required ...
  • The water retention properties of biochar derived from broiler poultry litter as applied to the Botswana soil 
    Shomana, Thapelo; Botha, Daniel Erich; Agachi, Paul Serban (Dama Research Center limited, 2020-05-14)
    Crop farming in Botswana is very modest and of high risk compared to its neighboring countries because of significant dependency on reduced and unreliable rainfall and as a result of soils with poor water holding capacity ...
