Analysis of Different Techniques for Improving Performance of Flat Plate Solar Collectors for Fruits Drying
Bakari, Ramadhani; Minja, Rwaichi; Njau, Karoli (Tanzania Journal of Engineering and Technology (TJET), 2014-06)Fruits drying had become a broader technology in fruits and vegetables value addition. The technology is reported to be a promising way of dying without incurring higher cost but its adaptation has not been feasible in ... -
Catalytic supercritical water gasification of biomass waste using iron-doped alkaline earth catalysts
Bakari, Ramadhani; Kivevele, Thomas; Huang, Xiao; Jande, Yusufu (Springer Nature Switzerland AG., 2022-05-18)The objective of this study is to optimise the process of supercritical water gasification of rice husk biomass utilising a low-cost catalyst made from alkaline-earth materials. The interactions between catalyst loading ... -

Ripanda, Asha; Rwiza, Mwemezi; Nyanza, Elias; Bakari, Ramadhani; Miraji, Hossein; Njau, Karoli; Vuai, Said; Machunda, Revocatus (Elsevier, 2023-02)This dataset expresses the experimental data on the batch adsorption of ciprofloxacin and lamivudine from synthetic solution using jamun seed (JS) (Syzygium cumini) biochar. Independent variables including concentration ... -
Effect of Glass Thickness on Performance of Flat Plate Solar Collectors for Fruits Drying
Bakari, Ramadhani; Minja, Rwaichi; Njau, Karoli (Hindawi Publishing Corporation, 2014)This study aimed at investigating the effect of thickness of glazing material on the performance of flat plate solar collectors. Performance of solar collector is affected by glaze transmittance, absorptance, and reflectance ... -
Experimental analysis of air flow patterns in perfomance of flat plate solar collectors
Bakari, Ramadhani; Minja, Rwaichi; Njau, Karoli (African Journal of Agricultural Research, 2015-02-05)Solar drying is one of the promising methods of reducing post-harvest losses in rural areas. Studies have shown that, heat transfer mechanisms in a solar collector influences the performance of solar dryers. This study ... -
Optimization of sub- and supercritical water gasification of rice husk enhanced with iron-doped alkaline-earth catalysts
Bakari, Ramadhani (NM-AIST, 2022-05)Biomass is a promising renewable energy source widely available worldwide, particularly in developing countries where clean and affordable energy is a major problem. Biomass gasification is an attractive technology ... -
Removal of lamivudine from synthetic solution using jamun seed (Syzygium cumini) biochar adsorbent
Ripanda, Asha; Rwiza, Mwemezi; Nyanza, Elias; Bakari, Ramadhani; Bakari, Ramadhani; Miraji, Hossein; Njau, Karoli; Vuai, Said; Machunda, Revocatus (Emerging Contaminants, 2023-09-01)Antiviral drugs such as lamivudine have been globally identified in the environment and marked as emerging pollutants of concern due to their bioactive extremity. Following therapeutic uses, approximately 70% of the oral ... -
Simulation and optimisation of the pyrolysis of rice husk: Preliminary assessment for gasification applications
Bakari, Ramadhani; Kivevele, Thomas; Huang, Xiao; Jande, Yusufu (Elsevier B.V., 2020-09)Thermochemical conversion of biomass into useful products is a promising route to harness biofuels. This process is clean, renewable and can reduce the use of fossil fuel. In this study, SuperPro Designer (SPD) software ... -
Sub- and Supercritical Water Gasification of Rice Husk: Parametric Optimization Using the I-Optimality Criterion.
Bakari, Ramadhani; Kivevele, Thomas; Huang, Xiao; Jande, Yusufu (ACS Publications, 2021-05-18)In this study, rice husk biomass was gasified under sub- and supercritical water conditions in an autoclave reactor. The effect of temperature (350-500 °C), residence time (30-120 min), and feed concentration (3-10 wt %) ...
