Wood waste is employed as the feedstock for production of high-quality pyrolysis products such as bio-oil, bio-gas and biochar by microwave pyrolysis using ZnCl₂ and Fe(NO₃)₃ as additive at 400–800 °C. Pyrolysis temperature influences the yield of the pyrolysis products, which indicates that the yield of bio-gas increases and the yield of biochar decreases as pyrolysis temperature increases. The yield of the bio-oil is little influenced by pyrolysis temperature, which is restrained in the existence of ZnCl₂ and Fe(NO₃)₃. ZnCl₂ increases the furfural content in bio-oil. While Fe(NO₃)₃ promotes H₂ production during pyrolysis process. The maximum heating value of bio-gas produced at 800 °C is 12.26 MJ/Nm³. The added ZnCl₂ and Fe(NO₃)₃ increase the yield of the biochar, which also promote the formation of pore structure of biochar. The ZnCl₂ and Fe(NO₃)₃ are converted into ZnO and Fe₃O₄ onto biochar after pyrolysis, which could be used as the absorbent and photocatalyst for methyl orange removal.

_{以木材废料为原料，采用ZnCl 2}和Fe(NO ₃ ) ₃作为添加剂，在400-800℃下微波热解生产生物油、生物气和生物炭等优质热解产品。热解温度影响热解产物的产率，这表明随着热解温度的升高，生物气的产率增加，生物炭的产率降低。生物油的产率受热解温度影响很小，受ZnCl ₂和Fe(NO ₃ ) ₃存在的限制。ZnCl ₂增加生物油中的糠醛含量。而Fe(NO ₃ ) ₃促进H₂在热解过程中产生。800℃时产生的沼气最大热值为12.26 MJ/Nm ³。添加的ZnCl ₂和Fe(NO ₃ ) ₃提高了生物炭的产率，同时也促进了生物炭孔隙结构的形成。ZnCl ₂和Fe(NO ₃ ) ₃热解后转化为ZnO和Fe ₃ O ₄到生物炭上，可用作甲基橙去除的吸收剂和光催化剂。
