ENHANCING THE PYROLYTIC GAS PRODUCTION GENERATED BY SLOW PYROLYSIS USING A FIXED-BED PROLYZER

The biomass slow pyrolysis using the fixed-bed pyrolyzer is a simple and inexpensive technique that can be used in small farms comparing to complex expensive technology of fast pyrolysis. However, primary produces bio-char lower yields bio-oil pyrolytic gas. Thus, there urgent need enhance gas production under conditions on account due advantage wide applications farm. Hence, this work aims fabricate operate small-scale fixed bed productivity from ground pieces Mango trees Pruning Logs (MPLs) (heating rate 0.01-1 oC/s, vapor residence time 4 min.) full absence oxygen. was investigated different final temperatures 300,350 400°C, particle length ranges 1-5, 10-15 20-25 mm. obtained results revealed that, increase temperature 300-400°C decrease MPL 1-5 mm accompained with explicit increment concentration, yield, higher heating value (HHVg) energy conversion efficiency by about 34.28%, 61.15%, 12.68% 66.10%, respectively along high concentrations combustible gases )e.i. H2, CH4). Additionally, optimal cost per unit (0.085 EGP/MJ or 0.005 $/MJ) than natural LPG 11.45% 75.07%, respectively.
