Abstract

In the present work, the pyrolysis of para grass (PG) and phumdi (PH) biomass samples was conducted in the temperature range of 300-500 °C to obtain the optimum temperature for obtaining the maximum yield of bio-oil. Further, co-pyrolysis experiments of PH and PG were also conducted at the same optimized temperature and varied compositions to investigate the synergistic effect. It was observed during the co-pyrolysis, that the maximum bio-oil yield of 37.80 wt% was obtained at the mass ratio of 1:1. The GC-MS, FT-IR and ¹H NMR analysis revealed that the bio-oils produced from all the processes were rich in functionalities. Phenolic compounds such as 2-methoxy-4-vinyl phenol, phenol, 2-methoxy, phenol 4-ethyl constituted a significant portion of bio-oils. The biochars obtained at the optimum pyrolytic conditions were analyzed by FT-IR and TOC analyzer.
