- Description: This paper reviews the potential of using waste tyre pyrolitic fuel as an alternative energy taking into account its environmental impact and national regulations. The properties of tyre derived oil and its derivatives were evaluated as a potential alternative low cost fuel for various industrial applications. The benefit of pyrolysis versus landfill disposal of waste tyres while producing low cost fuel and other value add products remains a driving force for this initiative. The downstream challenges associated with combustion of high sulphur bearing fuels such as tyre pyrolitic fuels calls for more research to into purification and refining of these fuels. Environmental Legislations on permitting the fuel production facilities, blending of the fuel derivatives with existing commercial diesel need to be clearly defined and facilitated accordingly.

- Description: This research reports the experimental investigation of single pass filtration of tyre derived fuel and low sulphur diesel blend using a bench scale two stage micro-molecular filtration set-up. Crude tyre pyrolitic oil obtained from slow pyrolysis of waste tyres was distillated at 250ºC to recover the light to medium fraction from the oil. The distillate was characterized and blended with low sulphur diesel at a volume ratio of 1.5:1 for bench scale filtration tests. Optimum packing densities for both micro and molecular filter media were determined followed by single pass filtration to evaluate the contaminants removal efficiencies. It was observed that the selected packing density of 168kg/m3 and pattern for micro filter medium can remove up to 2.5μm particle size in the fuel. The 18% reduction in total sulphur in the fuel after filtration was an indication of liquid phase mass transfer (molecular filtration) on the active surface of the molecular sieves.
