Optimization of Calorific Value of Densified Bush Mango Shell and Palm Pressed Fibre Briquettes

Energy value of biomass materials can be enhanced through composition, densification and process parameter manipulation. In this study, briquettes bush mango shell (BMS) palm pressed fibre (PPF) compositions were evaluated its calorific values optimized. The effects concentration, dwelling/compaction time compression pressure on investigated for briquette samples in the BMS: PPF ratios 100:0, 75:25, 50:50, 25:75, 0:100) as sample A, B, C, D E respectively. An empirical prediction model combustion property was developed optimized using response surface methodology. It observed across that composition increased, improved significantly from 12.4kJ/kg to 18.65kJ/kg. Increase dwelling also showed slight increase samples. optimum 19.03 kJ/kg B (75:25 ratio) realized at 40 minutes 25MPa adequately predicted by a reduced second order model. accuracy over 98% (Pred. R2 0.9858) with Coefficient Variance 0.64% Adeq. Precision 63.936. Thus, Sample possess properties burning rate 0.472g/min conditions hence suitable adoption investors renewable energy sector.
