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　bio-mass　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%.　(C)　2022　SAAB.　Published　by　Elsevier　B.V.　All　rights　reserved.
