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