  "description": "<p>The aim of this study was to convert HDPE and PET waste plastics into valuable hydrocarbon<br>\nliquid fuel via catalytic pyrolysis technique using silica-alumina as a low-cost catalyst<br>\nsynthesized from rice husk and aluminum oxide. HDPE and PET waste plastics were<br>\ncatalytically degraded in a muffle furnace at a temperature of up to 450 &deg;C using silica-alumina<br>\ncatalyst in catalytic pyrolysis of the same feedstock for optimum catalyst-to-plastic ratio of 1:3<br>\naccording to literatures. Optimum yield was obtained at this catalyst-to-plastic ratio with a yield<br>\nof 50.90, 6.10%, 43.00 wt% for liquid, solid and gaseous products, respectively for HDPE waste<br>\nplastics whereas for PET only solid residue was obtained. The catalyst was characterized by<br>\nXRD, FTIR and GC-MS. The ultimate and proximate analysis of the HDPE feed carried out<br>\ngave combustible moisture content of 5.70 %, fixed carbon of 11.56%, Ash content of 10.05%,<br>\nVolatile matter content of 72.69%, fixed carbon content of 11.56%, calorifc value of<br>\n46.70 MJ/kg and elemental composition with carbon (83.65%), hydrogen (12.72%), oxygen<br>\n(1.50%), sulphur (0.70%), chlorine (2.25%), and nitrogen (1.37%). The properties determined<br>\nwere density, viscosity, flash point, fire point, pour point, and calorific value for HDPE feed<br>\nstock. Whereas, the ultimate and proximate analysis of PET feed gave moisture content of<br>\n4.74%, ash content of 11.67%, volatile matter content of 73.53% and fixed carbon content of<br>\n9.06%. The results suggest that catalytic pyrolysis produced liquid products for HDPE feed stock<br>\nonly, whose properties are comparable to conventional fuels (gasoline and diesel oil).</p>",
