CONVERSION OF ALGAL BIOMASS VIA PYROLYSIS PROCESS INTO PYRO-CHAR PRODUCTION AT WASTEWATER TREATMENT NRC BAIJI

Herein, the algal biomass (AB) was crushed for converted into sustainable, renewable as alternative fuel (pyro-char) by pyrolysis processes during effect of reaction temperatures and contact times. The pyrolysis processes accord by drying AB at 105°C for 24 h to ensure the dried status. In this experiment the range of temperatures by 5g of OS-AB, 5 L h-1 flow rate of N2 pressure, with a fixed residence time of 60 min, and a range of temperatures of 300, 500, and 700°C, were called (AB@60min-300°C, AB@60min-500°C, and AB@60min-700°C) respectively. Optimum pyro-char was produced at 60min, 500°C. At the range of duration times with fixed temperature at 500°C optimum temperature was found in the previous run, and the range of the residence time of 30, 60, and 90 min, were called (AB@500°C-30min, AB@500°C-60min, and AB@500°C-90min) respectively. Optimal pyro-char created at 500°C for 90 min. The energy characteristics of AB and pyro-chars comprised high heating value (HHV), proximal and ultimate analysis, energy recovery (ER), energy yield (EY), atomic ratio, and fuel ratio (FR). The findings revealed that AB had the highest carbon content and HHV. Despite the presence of contaminating components, AB pyrolysis might provide pyro-char (solid carbon fuel) for electricity generation at NRC Baiji.
