- HZSM-5 has a strongest deoxygenating effect.
- NaY has a special performance in promoting the formation of phenol.
- The influence of HSAPO-34 is weakest to all components.
- Different catalytic behaviors related to their acidities and textural structures.
The lignin-rich biomass materials can widely be obtained from the resources of black liquor and lignocellulose fermentation residue. The reutilization of the waste lignin-rich biomass material relates to environment, energy, and materials, and thus worth for investigation with great enthusiasm. In this paper, the pyrolysis of corn straw fermentation residue (CSFR) under catalysis of three zeolites of HSAPO-34, HZSM-5, and NaY zeolite were investigated via the instrument of Py-GC/MS. The results showed that the main pyrolytic products were alkoxy phenols, alkoxy aromatics, 2,3-dihydro-benzofuran, alkyl phenols, and alkyl aromatics. Additionally, some acids, long-chain hydrocarbons, and saccharides were also identified. Comparatively alkyl aromatics could be more generated under the catalysis of HZSM-5, while NaY zeolite promoted the formation of phenol more distinctly. HSAPO-34 exerted a weakest influence to all product components with close similarities to the non-catalytic curves. The different catalytic behaviors of the three zeolites could be attributed to their different acidities and textural structures.
