Abstract
- Graphical abstract for the production of value add biomass sources. [Display omitted] • Herein, we used dual catalyst by generating maximum yield of 44.058 wt.% of bio-oil and gas yield of 28.942 wt.% along with 27.00 wt.% of bio-char. While in thermal pyrolysis of lignin the bio-oil yield of 40.79 wt.% and gas yield of 29.7 wt.% along with 29.51 wt.% of bio-char is achieved. • The biomass product (gas and Bio-oil) was characterized using GC-FID and GC–MS. The dual catalyst bed showed a considerable effect on the bio-oil composition and oxygenates were reduced. • The bio-oil exhibit a high quantity of phenols and aromatic. In the gas product, the H 2 yield has been enhanced from 28.97 mL/g to 42.68 mL/g and CH 4 yield enhanced from 32.07 mL/g to 40.44 mL/g. In this study, we developed an effective method for converting lignin into useful compounds to replace fossil-based products. The dual catalyst bed was used to catalyze the resulting pyrolysis vapors over it. A maximum bio-oil yield of 44.058 wt.% and gas yield of 28.9 wt.% along with 26.52 wt.% of bio-char is achieved. The biomass product (gas and Bio-oil) was characterized using GC-FID and GC–MS. The dual catalyst bed showed a considerable effect on the bio-oil composition and oxygenates were reduced. The bio-oil exhibit a high quantity of phenols and aromatic. In the gas product, the hydrogen yield has been enhanced from 14.6% to 21.4% and methane yield was enhanced from 20.8% to 23.1%.
