“…Thus, a higher bio‐oil yield can be obtained in biomasses having higher amounts of volatile matter and a lower amount of ash. The percentage of the lighter components was found to be lower in the case of the twin‐screw reactor in comparison to a fixed bed reactor as also being observed by other workers 19 . The pyrolysis experiments were performed at the temperature of 500°C, at a nitrogen flow rate of 526 mL/min, the residence time of 2 min.…”

Summary Fast pyrolysis of six biomasses mustard, camellia, pinewood, sawdust, bamboo, and bagasse was completed at a temperature of 500°C in a fixed bed reactor and a twin‐screw reactor. It was found that the yield of bio‐oil varied from 48 to 30 wt% in fixed bed reactor and 52 to 39 wt% in a twin‐screw reactor, whereas pyrolysis gases yield ranged from 34 to 20 wt% in a fixed bed reactor and 32 to 16 wt% in twin‐screw reactor and biochar yield ranged from 36 to 24 wt% in fixed bed reactor and 32 to 16 wt% in a twin‐screw reactor. High heating value (HHV) of bio‐oil was found to be maximum for bamboo (24.45 MJ/kg) biomass, whereas in the case of biochar, the maximum HHV was obtained for pinewood (27 MJ/kg) and sawdust (28 MJ/kg) biomass. On the characterization of the pyrolysis products, it is found that char obtained comprises mainly carbon while the liquid product, that is, bio‐oil, is a mixture of hydrocarbons. The pyrolysis gases consist of a mixture of carbon monoxide, hydrogen, carbon dioxide, and nitrogen. Novelty Statement Biofuel production uses various biomasses via two different reactors that is, a fixed bed reactor and a twin‐screw reactor. The yield of oil in the range from 48 to 30 wt% in fixed bed reactor and 52 to 39 wt% in a twin‐screw reactor and biochar yield ranged from 36 to 24 wt% in fixed bed reactor and 32 to 16 wt% in a twin‐screw reactor. The high heating value (HHV) was optimum for bio‐oil produced via bamboo biomass (24.45 MJ/kg) whereas HHV for biochar produced via pyrolysis was found to be optimum for pinewood and sawdust biomass (27 MJ/kg and 28 MJ/kg).
