Nitrogen-doped biochar catalyst was used to pyrolyze bamboo to produce valuable 4-vinyl phenol (2500 yuan\/kg) under NH<sub>3<\/sub> atmosphere, and in-situ regeneration of the catalyst was realized. NH3 and nitrogen-doped biochar catalyst could significantly increase bio-oil yield (up to 68 wt.%) and phenols content (80%). The selectivity and absolute yield of 4-vinyl phenol were up to 28% and 5.85 wt.%, respectively. N\/O-containing groups in the catalyst and free radicals from NH<sub>3<\/sub> promoted the break of ester bonds and \u03b2-O-4 bonds, and converted phenols intermediates to 4-vinyl phenol. Meanwhile, NH3 also acted as activator and nitrogen dopant, which realized the in-situ regeneration of the catalyst. The regeneration rate of nitrogen content and SBET of the catalyst was up to 84.5%-150% and 72.9%-85.4%, respectively. In addition, the nitrogen-doped biochar catalyst also showed good stability and reusability, and the yield of 4-vinyl phenol was still as high as 5.85-6.05 wt.% after repeated use of BC10 catalyst for 3 times. This was also the first time to explore the formation path of 4-vinyl phenol and the in-situ regeneration mechanism of the catalyst, based on the synergistic effect of NH<sub>3<\/sub> and the nitrogen-doped biochar catalyst. It proposed a new direction for the high value utilization of biomass resources.<\/p>\n<p>Related results were accepted in Industrial Crops and Products\uff1a<\/p>\n<p style=\"text-align: justify;\">W Guo, Y Wang, W Chen*, GX\u00a0 Xu, G Zhu, GXie, LXu, <strong>Zhen Fang<\/strong>, Q Zhang, H Yang.
