22. Batch Sorption Studies of Aqueous Cadmium and Lead from Contaminated Water onto Selected Biosorbents
Abstract : Groundwater, wastewater, surface runoff and surface water samples from Lake Victoria basin, Uganda was assessed for trace metals contamination. Untreated, base-treated and peroxide-treated biosorbents from Albizia coriaria, Coffea canephora, Cyperus papyrus, Erythrina abyssinica and Musa spp were investigated for removal of selected trace metals from contaminated water in batch studies.

23. Investigation of CO2 interactions with cellulose dissolved in the NaOH(aq) system
Abstract : Cellulose derived from wood can be used as raw material for production of textile fibres, making it a renewable alternative to fossil oil. One of the key steps in this process is dissolution of the cellulose. READ MORE

24. Selective Catalytic Reduction of NOx: Deactivation and Regeneration Studies and Kinetic Modelling of Deactivation
Abstract : Selective catalytic reduction of NOx (SCR) has been recognised as an effective post-combustion method for reducing nitrogen oxides from stationary sources. The cost of replacing the catalyst is a major part of the maintenance of the SCR system, hence it is desirable to advance methods to prolong the catalyst life. READ MORE

25. Hydrodeoxygenation (HDO) catalysts Characterization, reaction and deactivation studies
Abstract : Production of biomass derived fuels such as renewable diesel, are primarily intended to reduce the reliance of the conventional engines on petroleum fuels as well as the emission of CO2 from fossil hydrocarbons. Hydrodeoxygenation (HDO) is a powerful technique that has been regularly used in the fuel upgrading processes. READ MORE
